Light and How Cannabis Consumes It

In the eons before dinosaurs, plants dined on light.

During the early formation of our planet, there was no oxygen to breath, only water and light. This paradise of water and photons gave rise to the first plants. Not like the orchids and redwoods we are accustomed to today, early plants were mostly algae in the early oceans. These early plants developed a way to transform light into food.
By using sunlight to convert light energy into chemical energy, plants were able to store it for later use. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll pigments.
In plants like cannabis, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells. In the light-dependent reactions, one molecule of the pigment chlorophyll absorbs one photon and loses one electron. This electron is passed to a modified form of chlorophyll called pheophytin and the process propels a chain reaction of life.
cannabis lights

Plants can use light from across the visible spectrum for photosynthesis.

Yet some wavelengths of light are more useful to a plant than others. Wavelengths that the plant uses a lot of get absorbed into its leaves and stem while wavelengths they don’t use get reflected back. We only see plants as green because they don’t use green light energy. They reflect the one color they don’t photosynthesize so we perceive them as green.
Because of how plants evolved their ability to photosynthesize, different wavelengths are needed in greater amounts at certain stages of a plant’s growth, such as the blue and red. Light high in the blue range enhances vegetative growth, while red light strongly influences flowering and fruiting.
What we perceive as visible light is comprised of seven main colors. All the odd colors we see like pinks, browns, and beiges are just mixtures of other colors. Our eyes can only register wavelengths of light are within the 400 to 700nm range. Below 400nm, we move towards ultra violet, x-ray and finally gamma rays. Above 700nm is infra red, then microwave and finally radio waves.

Let’s start with some measurements.

Nanometres (nm) are a measurement of light waves. Each degree in Kelvin (°K) rates the ‘temperature’ of a light and offers an indication to the peak nanometers (nm) or color within the spectrum. The lower the nm, the more blue the light appears while higher numbers look red.
Marijuana uses light from approximately 420nm through to 750nm. But what does that mean? To understand the unique diet of cannabis (and make those real yield gains) we need to create the ideal environment for the plants.
Giving them just any light simply won’t do if the goal is heavy crops (and who doesn’t want that?). Normal incandescent bulbs produce more high energy wavelengths like infra red (heat) and midrange light (550-650nm) than anything else. Anyone who has tried to grow a plant in a room lit only by incandescent bulbs can attest to their poor performance so avoid trying to grow with them.

Even light in the right wavelength may not have the right amount of lumens.

Cannabis need light from the right part of the spectrum with the right amount of intensity to encourage proper yet fast growth. Marijuana evolved to grow under sunlight which changes intensity over the seasons. Young weed plants can be easily burned if put under the same intensity of light as a mature ones.
For this reason, many cultivators use different lighting techniques for the different stages of plant growth. Fluorescent lights produce the right wavelengths for growth but lack the intensity of other lighting options making them the standard for use with seedlings and young clones. HPS (High Pressure Sodium) and MH(Metal Halide) are industry standard lighting options that are used during vegetative and flowering stages although LED (Light Emitting Diode) are quickly establishing themselves as premium lights in the market.
HPS light

There are a few different types of light.

HPS lights offer light from approximately 540 through to 700 nm, typically yellow, amber and red light so they are great for flowering/budding marijuana. These lights tend to burn hot and need to be ventilated as well as hung from a decent distance from the plants. This makes having a tall area to grow in a priority. Luckily, the light produced by HPS lights penetrates deeply into thick canopies which is perfect for the flowering stage when buds and leaves are competing for room.
MH lights offer light from approximately 350 to 550 nm in the blue, green to yellow range.  However exact levels depend on what lamp your purchase as some lamps are ‘cooler’ and others a bit ‘warmer’ than average. MH lights are good for the vegetative stage but not as much for the flowering/bud stage.

Lighting is going high tech.

LED grow lights can have a mix of LED diodes in a single ballast or specialized ones. This gives cultivators one more variable to work with but it also opens up a whole world of adjustment. With the increased lifespan of diodes over bulbs, reduced energy consumption and lower heat production, it is easy to see why cultivators are switching to LED.
While LEDs are far more efficient then HPS or MH lights (with almost 30% savings reported on average) they come with a significantly higher initial price tag. Small projects and weekend cultivators may not want to shell out the cash needed to obtain a quality growing LED but commercial outfits normally opt to go with the reduced energy consumption and quickly make back the difference in initial price.
LEDs also have the benefit of not needing specialized heat venting as they produce almost no heat.  While HPS and MH lights require ducting, fans and additional controllers, LED lights don’t need any of that while providing a dynamic mix of color temperatures. The best LEDs are full spectrum and use some blues, some reds and a very stable white to create broad (full) spectrum LED grow light. These are the new breed of grow light and cover the full light range from around 420 through 750 nm.

Concentrates and Extraction Techniques

Concentrates are becoming a major player in the cannabis industry.

The word “Concentrates” often refers to the wax you vaporize, the tincture under your tongue, and your orally administered CBD oil. The potency of these cannabis products is steering consumers toward the more concentrated forms of weed. This is especially true as the therapeutic potential of non-smoking consumption is becoming better known.
People around the industry are taking notice of the meteoric rise in popularity of concentrates. OpenVape CEO Ralph Morgan believes cannabis concentrates will be more popular than smoking buds in the coming years. “I see concentrates becoming a part of folk’s daily regimen,” Morgan said in an interview.
The Cannabist’s concentrates expert Ry Prichard agreed with Morgan’s statement and his timeline. “Most of the clients that I work with have seen their sales go from 20 percent to 30 percent to 40 percent and now they’re about even,” Prichard said, “and a lot of shops, especially on the boutique end of the spectrum, are 70 percent concentrates.”

Concentrates make up a large segment of the current market.

Under the rubric of cannabis concentrates falls anything created through an extraction process. Solvents like butane, propane and CO2 strip the active compounds from the cannabis plant. Solventless processes also exist that can produce increadibly high concentrations as well.
Some types of extracts test in the 70-80% THC, while others are instead rich in non-psychoactive compounds like CBD. There are a lot of intricacies to cannabis and new methods of extraction are being developed regularly as the market expands. Here is a quick rundown of the most popular products the average consumer can buy that fall under the rubric of “concentrates”.

Solventless Extracts

Many solventless extractions are offered in less stable, sappy forms. Their color can vary from a golden opacity to a darker amber depending on production factors. Cure time and starting material play a big role in dialing in these nuances.
Heat, pressure, and exposure can impact the consistency of these products. Higher temperatures tend to create stable products that more resemble shatter, whereas lower temperatures often produce sappier, less stable products. Both high and low temp products appear on dispensary shelves these days and have begun to form respective niche markets.

Kief


Also known as dry sift or pollen, kief is made up of the resin glands called trichomes on cannabis flowers. These glands produce the terpenes and cannabinoids that bring the diversity of flavors and effects to cannabis. Kief is often used to make hash and is commonly collected in a grinder. It is normally sprinkled onto flower cannabis or vaped directly for a more potent high than smoking flower alone.

Rosin


Rosin opened the door for several different new products. Solventless shatter, a type of rosin that maintains a glass-like consistency, may resemble butane hash oil in appearance but is manufactured with nothing more than heat and pressure. Hash oil of this consistency is obtained through the acquisition of key genetics and the right combination of heat, pressure, and exposure to heat.

Hash


One of the oldest products in the cannabis industry is has. This concentrate is made by compressing the plant’s resin. Where kief preserves the structure of the trichomes, hash tries to merge them into a single superstructure. The powdery kief normally that coats your cannabis flowers can be collected and pressed together to form hash.
Solvents like ice water or ethanol may be used to more effectively strip the plant of their cannabinoid-loaded crystals but are not required. This method produces less potent results than BHO and other cannabis concentrates but remains a staple of cannabis culture around the world.

Budder

Another variation of hash is budder. Also called cake batter or “whipped” rosin, these products are created by incorporating light heat and agitation to rosin. The result is a whipped consistency that looks very similar to a salve of some sort. This technique has been known to significantly increase the aromatic properties of the hash oil it uses.
This method provides a new creamier texture that can be much easier to work with than shatter or sappy consistencies. While many retailers are beginning to sell whipped hash oils, the process can be achieved easily at home with preexisting rosin by simply stirring it with a warm dabber tool.

Solvent Based Extracts

Butane and propane are popular solvents used to extract cannabinoids like THC and CBD from cannabis plants. They are some of the more dangerous methods as well due to the explosive nature of the two solvents.
Extraction can be done at home using simple equipment and is also done on large scales, but the process is almost the same. To start, fill a tube (metal or plastic) with plant material. The quality of the material used directly affects the quality and yield.

C02 Oil

CO2 Concentrates
Supercritical fluid extraction is another method commonly used to extract cannabinoids. While it is possible to use other gasses, C02 is the most commonly used gas for this method. CO2 has the benefit of not causing harm if not fully purged from a product like butane.
C02 has become the connoisseur’s extraction choice because it goes past “critical” at around 90 °F, a temperature well below the deactivation temperature for cannabinoids. This means more flavor is preserved and a clearer high is produced than with other methods.
This extraction method relies on pressure and temperature to extract the terpenes, cannabinoids, and waxes from the cannabis material. Extractors use this knowledge of which temperature and pressure each terpene, cannabinoid, and wax separate them from the homogenous solution of marijuana material. This way they are able to target certain flavors and “types of high” produced by the genetics they are using or add additional flavorings.

Butane Hash Oil (BHO)

BHO, or butane hash oil, is an extremely potent concentrate used in dabbing and other vaporization methods. Cannabinoids are drawn out of the plant with butane which leaves behind a wax. The wax will either remain sticky or harden up, resulting in a crumbly “honeycomb” or a glasslike “shatter.” Because its THC content can reach into the 70-80% range, BHO is a popular remedy for people who need the highest concentrations available.
BHO is relatively easy to produce at home or in an industrial setting. After covering one end of a tube with a filter or mesh screen (with holes small enough to prevent plant material from seeping through), butane is sprayed into the tube. Refiners then allow the resulting cannabis-butane solution to drip into a glass dish below the filter end of the tube.
The butane must be purged from the solution for safety by heating the solution in a hot-water bath. The solution is slowly heated until the escaping gas produces bubbles.The water-bath quickly becomes cold, so it frequently changed or a heating plate is used until the solution is fully purged of solvent. The remaining “goo” is cooled and then used as the concentrate known as shatter.

Rick Simpson Oil (RSO)


In 2003 a man named Rick Simpson treated his skin cancer using a homemade cannabis remedy. By soaking the cannabis in pure naphtha or isopropyl alcohol and allowing the solvent to fully evaporate, a thick tar-like goo is created. Also known as Phoenix Tears, Rick Simpson Oil (RSO) can be ingested or applied directly to the skin. Many businesses sell their own renditions of the Rick Simpson Oil these days. Some are high in THC while others contain only non-psychoactive compounds like CBD.

Tinctures


Up until prohibition of cannabis in 1937, tinctures were the most common form of cannabis medicine in the United States. A tincture is a liquid concentrate using alcohol for extraction. Alcohol pulls out many of the plant’s beneficial cannabinoids and is stable to work with. A few drops under the tongue is a normal dose, but patients can safely use more as needed. Tinctures are a great way for patients to medicate without having to smoke and come in a variety of flavors.

Treating Common Cannabis Pests

Spider mites, thrips, fungus gnats…

If you are a cannabis grower you’ve likely been warned about these insects more than once. There are many pests that can endanger your crops. But some turn up a lot more often than others. Knowing how to identify and deal with the most common offenders can  be the difference between doing some extra work and losing a whole crop.
To start off, the best way to prevent a garden infestation is through prevention. Being aware of the symptoms and, above all, knowing how to eradicate them efficiently can save hundreds or even thousands of dollars. Not to mention months of caring for them. The main goal is to not give any potential pests or diseases a place to hide/nest/grow. This is best accomplished with some soap.
Wash the walls, floors and all surfaces with soap and water. Using diluted chlorine, bleach (although never together) or other disinfectant works too. Do the same with pots, buckets, utensils and any other equipment you plan to use. Make sure that nothing comes into the garden that might be able to carry stowaways.

It’s important to make sure everything is clean inside and out.

When changing reservoirs, make sure to wash and disinfect them as well. You never know what might be growing in there, even if the previous plant didn’t show signs of problems, eventually something will go wrong.
You may also want to cover the floor with plastic sheeting. The kind available at most home improvement stores but thick enough that you won’t tear through it. Carpets and similar flooring types make great homes for both pests and molds/fungi. Covering them with plastic ensures that they remain in good condition and won’t offer sanctuary to pests.
Keeping your air and water temperatures along with room humidity at the ideal levels while using adequate air circulation will prevent most pests/infections from ever getting started in a marijuana grow. As will filtering the air intake to block the path many marijuana pests use to gain access to the plants.

Soil-borne pests

One of the many advantages to using hydroponic/aeroponic systems to grow cannabis is that they prevent many insect and other infestations. There is no place for many types of larvae to incubate or hatch. When choosing soil, look for sterilized or composted soil. If using native soil, make sure to sterilize or compost it as well to prevent hitchhikers.
Covering soil in diatomaceous earth will prevent flying and crawling insects from laying eggs in your corp. This is because the sharp edges damage their tiny bodies like rubbing them across sand-paper. A less effective alternative uses a 1/2” or so of fine perlite on top of the soil as a barrier. Insect eggs generally don’t grow in perlite and most insects wont burrow deep enough to hit soil.

 Spider mites

garden pestsBest Prevention:
Keep the room clean throughout the grow. Fully disinfect and sterilize everything before attempting to start the grow. Also make sure to keep the room tidy and free of excess soil.

How to Identify:

Spider mites live underneath the leaves plants and are invisible to the naked or untrained eye. The mites drink the chlorophyll for sustenance. They also have eight legs which classifies them as a tiny spider instead of as an insect.
Spider mites are visible under a magnifying power of 15x or more. The magnified mites are whitish, red, or (most commonly) brown with two spots. These mites spin webs which makes them easier to spot. Once seen, it unfortunately means the mites are already a generation or two in.
Misting the undersides of leaves reveals the webs easily to the naked eye. Once fertilized, females remain so for life. After mating they can lay about 100 eggs every 5 days. With 75% of all spider mite eggs being female, their numbers can grow rapidly.

Repression Measures:

Spider mites ideal temperatures range between 70 and 80F or 21-27C. They also need average to high humidity to stay happy. Cooling a grow room to 60F/16C and dropping the relative humidity slows the reproduction rate of the spider mite.
Cooling the room reduces the damage an infestation can do. At 50% humidity and below the mites start getting uncomfortable. By spraying jets of water across undersides of leaves, growers can blast larger colonies loose and slow the spread of these pests considerably.

Best Predators:

Neoseiulus (Amblyseius) californicus and Mesoseiulus (phytoseiulus) longipes are the two most common and effective options out there. They can eat up to 20 eggs or 5 adult mites every day. And once their food supply runs out, they die off.

Sprays:

Neem oil is the most effective spray available. Other effective methods include pyrethrum, horticultural oil, and insecticidal soap. Spraying three times at 5 to 10 days apart should destroy a mite population if the room remains clean. Spider mite eggs hatch after 5-10 days which makes a second application necessary.
The first spray kills the adults while the second destroys newly hatched mites. A third application will kill any stragglers left behind. Make sure to also cycle to another chemical if using pyrethrum to spay frequently. This ensures mites don’t develop a resistance to the synthetic chemical. Several miticides have DDT or fungal relatives that are toxic if inhaled by humans so choose your miticide carefully.

Thrips

Best Prevention:

Keeping a clean grow area is the only defense against a thrip infestation. These miniscule insects avoid detection by even by the most cautious grower until they reach damaging levels. Best to make sure they don’t feel welcome in the garden in the first place.

how to Identify:

The thrip hits greenhouse more than any other garden. It’s difficult for the thrip to reproduce in large quantities outdoors and they must hitchhike into indoor gardens. Their small size helps them fit through all but the finest screens and finters.
Thrips can be almost any color, move very quickly and can fly which can make it hard to get a good look at them. Thrips tend to move in herds though, grazing tiny strips off the top of leaves like tiny lawnmowers. This can strip plants of chlorophyll so thoroughly that the leaves become brittle, dark, and begin to crumble. Tiny black lines across leaf surface are fecal trails left after gorging themselves.
The flying thrip easily infests gardens if protected from outdoor conditions. The female bores a hole into the plant and leaves her eggs in a hole. The opening is so small a magnifying glass is needed to even see it. In marijuana, the thrip colonies primarily infest and reproduce inside buds. A good shake of a cola infested with thrips produces a cloud as the tiny pests fall, jump and fly  out of the buds.

Repression Measures:

Using powerful fans to move air throughout a greenhouse or growroom can prevent the thrip from latching on to plants or taking flight. Regularly misting plants with water will flood the thrips and slow their travel, reproduction, and minimize their ability to damage the plant. Sticky traps do help, however the thip doesn’t migrate much. Which reduces the effectiveness of sticky traps.

Best Predators:

Nearly any predatory mite can effectively battle thrips. Parasitic wasps work but the size of thrip populations limit their ability to be effective. You might be able to see herds skittering across your plant. And while crushing them will reduce their numbers, it is of course not effective overall.

Spray:

Pyrethrum or insecticidal soap sprayed 2-4 times at 5-10 day intervals is the recommended treatment.

Fungus Gnat

Best Prevention:

Keep the relative humidity of your garden low, and don’t over water. Make sure the surface of your grow medium doesn’t stay soggy. Covering hydroponic medium surfaces also prevents growth of green algae which can entice these pests.

How to Identify:

Fungus gnats attack plants during their adult and larval stages. The maggots are almost invisible to the human eye. This is compounded by their see-through bodies and a black heads. The maggots infest the upper roots of plants and will spread throughout an entire hydroponic root system.
Fungus gnat maggots love dark, dank, and water soaked environments. Checking the medium at the base of a plant reveals these pests. The gnat larvae are also perfectly happy going through their life in rockwool. They infest root systems, damage larger roots and consume root hairs. This results in the plant weakening, slowing its growth, and visible fading of foliage.
Adult gnats are normally grey to black, so small they are hard to see and have disproportionately long legs. Females are prolifically breeders, laying an average of 200 eggs weekly. They can also usually be found at the base of your plant along with their maggots. They basically have a Hulk-like grip and are basically impossible to remove by force.

Repression Measures:

Damaged roots make marijuana insanely vulnerable to several types of fungus and prevents nutrient uptake. Maggots will consume decaying plant matter. This means that infestations reproduce faster the more damaged your plant becomes. Reducing surface moisture in your plants medium will slow fungus gnats reproduction dramatically. basically, the drier the better. Applying an anti-algae product to the base of plants kills any green algae currently growing. It also reduces the number of food sources of maggots. Yellow sticky traps placed 2 inches away from the growing medium will catch most adults looking to spread.

Best Predators:

There are no predators proven to be effective at controlling gnat populations themselves. Although the predatory soil mite Hypoaspis and the nematode Steinemema feltiae severely impact the insect population in soil grows. Unfortunately, they are not effective countermeasures for hydroponic applications. It is also impossible to force them out. Swatting a few adults doesn’t kill the eggs they lay underground.

Spray:

Neem or insecticidal soap applied as a soil drench kills eggs and larvae in 1-3 applications. Spray containing the fungal culture Bacillus thuringiensis var. israelensis (Bt-i) successfully eradicates adult gnats. The soil drenches and spray should be applied simultaneously every 5-10 days.

Do you agree?

There are way more ways to fight off these pests than I could possibly list on my own. Let us know in the comments below what pests you have come across and what you have found to be effective. I’d love to hear what else you think should have been included. Thanks for reading.

Cancer Treatments: Now With Marijuana

Marijuana is an old remedy.

Modern cancer patients aren’t the only people to understand the healing power of marijuana. Marijuana is the name given to the cannabis plant during 20th century prohibition. Cannabis grows wild in warm and tropical climates throughout the world and has been cultivated commercially for eons. Prohibition has given cannabis many other aliases as people developed code. Names like pot, grass, cannabis, weed, hemp, hash, hydro, ganja, and dozens of others all describe the same plant.
Records show marijuana has been used in herbal remedies dating back to the Chin Dynasty in China. Ancient doctors could see the effects of using cannabis as well as today and prescribed it for many maladies. The herb was so powerful that even the Romans put it in their medical texts.
Scientists have identified many biologically active components in marijuana that are the main reason it is so useful medically. These compounds are called cannabinoids. The two most studied of the hundred or so cannabinoids are delta-9-tetrahydrocannabinol (THC), and cannabidiol (CBD). Other cannabinoids are being studied but haven’t had the same amount of press or research put into them.

Is marijuana a legal treatment?

cancer treatmentAt this time, the US Drug Enforcement Administration (DEA) lists marijuana and cannabinoids as Schedule I controlled substances that cannot legally be prescribed, possessed, or sold under federal law. Whole or crude marijuana (including marijuana oil or hemp oil) are also not approved by the US Food and Drug Administration (FDA) for medical use whatsoever.
State laws have a little bit more play in them and diverge from the federal stance to different degrees. The use of marijuana to treat some medical conditions is legal in many states even though it remains federally banned. Each state has individual rules about how they deal with marijuana so it is important to research the specific rules for your state.
Dronabinol (pharmaceutical THC) and some synthetic cannabinoid drugs like Marinol are approved by the FDA. Marinol is used to relieve nausea and vomiting for chemotherapy patients in addition to being prescribed to AIDS patients for appetite stimulation.

Marijuana is more than THC.

Different compounds found in marijuana have affect the human body in different ways. For example, delta-9-tetrahydrocannabinol (THC) causes the mental high and can also relieve pain and nausea. At the same time it can reduce inflammation and act as an antioxidant. Cannabidiol (CBD) can help treat seizures, can reduce anxiety and paranoia, and can counteract the “high” caused by THC according to the American Cancer Society.
Different cultivars (strains or types) of marijuana can have varying amounts of the different cannabinoids. The specific ratio of cannabinoids produced by a plant is known as it’s strain profile and can be used to better judge what effects to expect from a specific strain.
The effects of marijuana also change depending on how it enters the body:

  • When inactivated or raw cannabis is eaten, the THC is absorbed poorly by the body. Once absorbed, it’s processed by the liver into a second psychoactive compound. The second substance acts on the brain to change mood and/or consciousness differently than THC.
  • When marijuana is smoked or vaporized, THC enters the bloodstream quickly, bypassing the liver at first. It is transported to the brain before the liver can convert a large amount of it into the second chemical. Because there is so much less of the second chemical, the high is stronger but fades quicker.

What can marijuana treat?

A number of studies using small groups of marijuana users found that cannabis can be helpful for treating nausea and vomiting from cancer chemotherapy. A few studies have found that smoked or vaped cannabis can be helpful in the treatment of neuropathic pain as well.
Smoked marijuana has also helped improve food intake in certain HIV patients during some studies. Clinical trials have also been shown marijuana extract users tended to need less pain medication than others. The pain relieving effects seem to be even better in the non-psychoactive cannabinoid CBD than with THC.

How does marijuana affect cancer?

According to the American Cancer Society, “…THC and other cannabinoids such as CBD slow growth and/or cause death in certain types of cancer cells growing in lab dishes. Some animal studies also suggest certain cannabinoids may slow growth and reduce spread of some forms of cancer.” While there have been some early clinical trials of cannabinoids in treating cancer, future studies are inevitable.
Most studies show cannabinoids can be safe in treating cancer. They do not however seem to help control or cure the disease. Relying on marijuana alone as treatment while avoiding or delaying conventional medical care for any issue (including cancer) may have serious health consequences.

What are the possible harms of marijuana?

While many insist marijuana can pose no harm to users, it is not true. The most common effect of marijuana is a feeling of euphoria. Yet the complex chemistry of the brain and cannabinoids indicates that there is a lot going on under the hood. Cannabis can lower the user’s control over movement, cause disorientation, and sometimes cause unpleasant thoughts or feelings of anxiety and paranoia. While the majority of users do not experience these negative effects, they are more common in new users who don’t understand their dosing requirements.
Smoked marijuana delivers THC and other cannabinoids to the body along with harmful substances. Tar is one of the substances found in both tobacco and cannabis smoke. Heavy users (more than one gram a day) of smoked cannabis also commonly report chronic bronchitis.

Make sure to do research.

Because marijuana plants come in different strains with different levels of active compounds, it can make each experience different. Even with good data from a state certified lab, the effects of a specific strain on a specific user can be very hard to predict. It can take time and experimentation to find the best treatment plan or strain for a specific issue.
Even though cannabis is not chemically addictive (like caffeine or an opioid) people can still become psychologically dependant. Users will not receive the life threatening withdraws like they do from cocaine but they may still feel the conditioned desire to use.  Treatments and attitudes toward addiction vary widely across countries and the globe. If you struggle with addiction or are interested in treating any malady, it is best to seek a spectrum of qualified professional help before committing to any treatment plan. Make sure to get more than your own opinion before you make potentially life altering decisions. Thanks for reading.

Weed Grinder: The Ultimate Buyers Guide

In the course of every cannabis consumers journey, the question of what grinder to use comes up. Are they even needed? Is it worth it to buy a high end model? Which one is best? There seems to be an infinite supply of identical products on the internet that come in a wild range of prices making the choice even more overwhelming.
The explosion of the legal cannabis industry has created room for a new generation of paraphernalia peddlers to rise and claim that their grinder is the best ever. Space Case, Medtainer, Phoenician, and Santa Cruz Shredder are just a few of the names that come up regularly in the conversation about quality. These companies have built a reputation for excellent products but cost a pretty penny.
Finding the right weed grinder can be a frustrating and expensive process. Nobody wants to spend $100 on a grinder only to find that a $5 one works better for them. Yet if a high end grinder is so expensive, shouldn’t it be that much better than a cheap one? But what it really comes down to is how it affects the smoking experience. Grinding is not required for most methods of cannabis consumption but it does a few really great things for it.

What does grinding actually do?

By breaking up the bud, more of the weeds surface area is exposed. Surface area is important for consuming cannabis flower. The higher the surface area, the more efficiently THC is vaporized so grinding will produce a stronger hit than otherwise.
Burning (or vaping) ground product also produces a more flavorful hit. Terpenes (the chemicals that make up smells) exposed by grinding increase the aroma before, the flavor during and the taste after a hit. It can be slightly harsher from the increased smoke density but the overall experience is of a higher caliber.
It’s not just the flavor that gets a boost either. Because of the consistent and small size of particles after grinding, it is easier to make every bowl the same size. Grinding simply produces a more consistent product to smoke or vape. People interested in monitoring the amount of cannabis they consume or trying not to overload a vape pen will find that grinding the product makes a big difference.
grinder

What is the difference between them?

There are a lot of options when it comes to getting an herb grinder. Most differences can be boiled down into variations of materials, styles and features. A $100 grinder may perform worse than a $5 version in many situations if it is significantly smaller/larger or produces a course grind.
When comparing grinders, it is important to think about how you intend to use it. If most sessions require less than a gram of product, a grinder that can hold an ounce of product will be less effective than one that can hold an eighth. People with arthritis or carpel tunnel may find a larger grinder with a crank handle easier to use than a small one with threads.
Cheap grinders also have a tendency to stick or jam up over time. Occasional users may not experience a perceivable difference between two models. If grinding cannabis is part of a daily routine, the smooth action of higher end models can make a big difference. Most of the difference between high and low end grinders is due to quality of materials and finishes.

What kind of materials and finishes are safe?

Grinders come in every material possible. From wood to titanium, as long as the material is stable enough, it can be used to make a grinder. That doesn’t mean that all materials are made equally though. Glass makes a great pipe but a very bad grinder. The brittle nature of glass makes chipping and breaking under normal use almost guaranteed so people don’t normally produce glass grinders.
Materials like aluminum and acrylic are cheap, stable and are unlikely to shatter under normal use so many manufacturers rely on them. Over time, grinders made from these materials will wear out and wear off. Small pieces of plastic or metal can work their way into the product you are grinding.
Materials like titanium, food grade polyethylene and ceramic are strong enough to resist wearing out and are significantly safer to use. Since titanium and ceramic are expensive to produce, many manufacturers will use an aluminum base and coat it with a thin film of the more expensive material. As long as the finish remains intact, there is little risk of contamination to the user and it then becomes a matter of style.

What are the main styles of grinder?

The most popular styles of grinder are manual and range from two to four pieces. Electric grinders are becoming more popular but have yet to dominate the market. They mainly serve the subsection of the community that loves gadgets or has motor-control difficulty.
Each style has a specialized use and will function better in situations it is designed for than the other styles. Manufacturers classify their grinders by the number of pieces and the diameter of the assembly.
Two piece grinders are best when used indoors and with a tray to dump the ground material. Three piece grinders remove the need for an extra tray while four piece add a screened off area at the bottom. The screen separates the trichomes that break off during the grinding process and collects them for later use.
Since trichomes are the plants chemical factories, this fine powder is very high in cannabinoids like THC and CBD. Vaporizers work best when using finely ground product so 4 piece models are very popular. Any style will produce vaporizable product as long as the teeth grind the cannabis evenly.

What about the teeth?

The parts of the grinder that actually do the work are called the teeth. They can come in a few shapes and configurations in any style or material of grinder. Their whole purpose is to break up the cannabis evenly but they go about it in different ways.
Pin shaped teeth are found on wood grinders pretty often and are better for grinding sage or thyme than cannabis.Diamond shaped teeth tear through dense nugs and can break up stems that are dry. They act like scissors, shearing the bud apart. They have straight sides and are the most common type of teeth on aluminum grinders.
Pyramid shaped teeth are able to produce a more consistent grind than diamond teeth but also produce smaller chunks. These are common on higher end grinders but can still be found on low end models. If these teeth are cheaply produced, the tips can sheer off and contaminate the cannabis. Inhaling burning acrylic or aluminum is dangerous and can have long term health consequences so they are best to avoid.

What size is right?

Most stores will stock a few different sizes of the same grinder. The manufacturers classify their sizes based on diameter. So a 2.5″ grinder is about two and a half inches from side to side. Each size generally corresponds to a different product amount. 1.5″ models are great if grinding less than 2 grams of cannabis while a 3.5″ model will chew through an ounce in no time. In the end, it comes down to personal preference and need. Does it feel good in the hand? Does it have the right number of pieces? Is it made of high quality materials? If so, it should serve you well in the years to come. Thanks for reading.

Grow Lights: How to Choose the Right One

It is tempting to believe that there is such thing as the perfect grow light. A single radiant source that simply out performs everything else out there. Such a light does not exist at the moment but we have a few options. Even sunlight (the full spectrum, nuclear powered, plasma-based grow light in the sky) can damage plants if the rest of their environment is not well suited to them. Cultivators have to choose the right grow light for the right situation.
There are a few key considerations when debating between the most common lighting methods available. Using good old sunlight should work if you live anywhere near the equator but for those in the north or south need to rely on artificial means if they want to produce all year. Different growing techniques lend themselves to different setups as well.
Plasma, Induction, Ceramic Metal Halide, there are a lot of variations when it comes to lighting but for todays discussion we will be limiting the conversation to the three most popular methods. The lights we will discuss are easily obtainable, proven effective and utilized across the industry as the benchmarks that all others must compare to. There is a bit of variation within each category but they all function similarly (although you may need more than a wall socket for some).

Cultivators must consider the size of their garden.

Using a 1000-watt grow light in a two-foot by four-foot closet is generally wasteful and can lead to a lot of unnecessary problems like overheating. On the other hand, trying to cover a commercial garden with a 40,000 sq. ft. canopy in Compact Florescent Lights (CFL) won’t produce the same level of production as other lighting methods.
Growers working with small spaces need to prioritize heat dissipation over light penetration. While higher wattage lights provide more energy for your plants to work with, if the heat they produce is too much, it can stunt the plants growth. Using Compact Florescent (CFL) ballasts over High Pressure Sodium (HPS) or Metal Halide (MH) options can reduce heat buildup in small spaces while Light Emitting Diode (LED) ballasts provide a balanced mix of heat and light at a higher price point.
If you are growing more than 2-3 plants and have enough space for dedicated heat exhaust ducting, an HPS or MH light might be the right solution. The extra space needed to process the heat given off by these lights is made up for in high production levels. There are several sizes ranging from 150 up to around 1000 watts and each is designed to cover a different sized area.

Complexity is also a major consideration with grow lights.

There is a lot more to growing dank herb than sticking a seed in the ground and waiting for mother nature to work her magic. Top producers monitor every element of their operation with grow logs and performance metrics. Most growers can get away with going by eye and only measuring when they must but that won’t produce those head-sized colas that win competitions or get featured on the cover of High Times.
Adjusting CO2 generators, maintaining air conditioners and dehumidifiers, setting timers, calibrating sensors and monitoring schedules are all part of a commercial operation and can quickly add layers of complexity to a seemingly simply project. Getting the most advanced or largest lights possible may add extra layers of complexity like running exhaust ports, vent fans and electrical lines.
Having to install an extra circuit breaker is pretty frustrating but having to get the power company to upgrade the lines and transformers heading to your place in order to put in extra HPS lights can run into the tens of thousands of dollars. Using LED lights may have a higher initial investment cost (making quality versions expensive) but the energy savings add up over time.grow light

Budget is always important with grow lights.

Sometimes bigger isn’t better. If all you are doing is looking to offset the cost of buying cannabis, getting a massive light and converting the garage into a clean room worthy of NASA may not be the best route. A low cost (albeit moderate output) closet operation may work better, especially if you don’t consume only the freshest of rosin.
There are tons of options on the market for a small space grow operation with everything in a single kit. The kits normally come with a light, maybe a few pots or hydroponic bays, and they actually work pretty well (in general). They are more expensive than building it yourself but offer significantly higher quality than most people can cobble together on their own. If your goal is to make money, customization is the name of the game.
Installing LED lighting in an industrial in-door grow operation is almost a must. The initial cost is more than offset by the increased operational life of the ballasts along with the drastic (up to 30%) savings on energy. Industrial and commercial operations may still utilize CFL lights for seedling growth given the low overall cost of operating fluorescents.

When it all comes down to performance, a leader emerges.

In the end, we all want the best bang for our buck. CFL’s are great for seedlings/clones but not great for vibrant vegetative/flowering growth. Their low operating temperature also makes using them fairly basic. A low-cost alternative to LED’s for small-scale growers, CFL’s offer a solid base of performance to work up from.
HPS and MH lights offer greater output than CFL’s and are best for medium to large operations. They are specialized to vegetative and flowering and scale well for larger operations. The excess heat HPS and MH light produce compared to other options needs to be dealt with through specialized ducting or increased air conditioning but many ballasts offer specialized ports to make this easier for large strings of grow lights.
LED grow lights offer the highest performance of any grow light option but also come with the highest cost. While they don’t require the ducting of the HPS and MH lights, LED’s provide as intense of a light as any other option.  In addition to being the right intensity, LED’s require far less maintenance with a projected operating life measured in years, not months.

What is your end goal?

We have only toughed on the surface of grow lights and how to choose between them. If you want to get started quickly and easily, look into an assembled unit. It makes all the difference to have a station ready for you and not have to make all the little decisions yourself. Once you get the feel of things, you will likely be able to work with the prebuilt to fit your preferred style of growing until you are ready to do things a little bigger.
If your goal is to make money and you are just getting started, investing in HPS and MH lighting for vegetative growth and flowering along with some CFL may be the right call. Their overall cost is doable and they provide a great end product with a few extra considerations.  This is the most common setup for small to medium indoor growers looking to turn a profit.
If money is no object or you are working on a massive scale, LED lights provide the best returns over time. With minimal energy drain compared to other lights and the low operating temperature makes the energy savings a real consideration. Many units can also provide full spectrum light or specialized wavelengths for different plant cycles making them more versatile than the HPS and MH which must be switched between cycles.

THC vs. CBD: What Do They Do?

Have you ever wondered what THC and CBD are?

For those who don’t know, tetrahydrocannabinol (THC) and cannabidiol (CBD) are potent chemical compounds produced in the trichomes on cannabis flowers. Trichomes are the small mushroom looking structures that sparkle like crystals in the light. Cannabis with a high concentration of THC or CBD is prized over just about anything else.
The states that allow cannabis sales require licensed retailers to prominently display the THC, CBD and possibly several other three letter words for everything with cannabis in it. People are always talking about how potent cannabis has become compared to times past and equating it with the THC and CBD content. This all points to THC and CBD being important, but why?
To start, cannabinoids are a group of compounds that our bodies and plants produce naturally. There are over 85 different cannabinoids identified so far with more just waiting to be catalogued. They are called cannabinoids because when Raphael Mechoulam  first identified them back in 1964, they were in the cannabis plants the Israeli doctor was studying.
Science has shown that our own bodies produce and process cannabinoids in immune and nerve cells. Humans are not unique in this ability to process cannabinoids either. The systems needed can be found in many mammals including dogs and cats.
Some animals simply can’t process THC and CBD. Insects like bees and ladybugs don’t have the right systems to be affected by the cannabinoids produced in cannabis. So even if insects or reptiles get covered in cannabinoids, it can’t get them high.
Science is discovering that the connection humans have to cannabis goes down to the molecular level. Continued research into the structure of THC and CBD has revealed that they are structural isomers. Essentially, they have the same basic parts but get arranged in a different way.

How do THC and CBD Work?

Cannabinoids like THC and CBD are able to bond with a special network or system of receptors in our cells. This system is present in most mammals, that is why cats and dogs will respond to cannabis in similar ways as you and I.
The specific receptors responsible for how weed makes us feel are called the CB1 and CB2 receptors. They were named after the different cannabinoids they are specialized to work with. I agree it’s not a very interesting name but being as simple as possible makes for easier science.
This system is called the endo-cannabinoid system. Endo for inside and cannabinoid for the type of chemical they work with. Cannabinoids like THC and CBD activate the receptors by mimicking the  neurotransmitters our bodies naturally produce called anandamides. Our bodies can’t tell the difference and accept the imposters without question. Yet each cannabinoid has a unique effect.

  • CB1 receptors respond to THC and are responsible for the psychoactive effects of cannabis. They are present in most of the brain and play a role in vital functions like; memory, mood, sleep, appetite and pain sensation. Cancer, insomnia, PSTD, MS, and many more disorders respond positively to CB1 stimulation.
  • CB2 receptors respond to CBD and are responsible for the anti-inflammatory effects of cannabis. They are found in immune cells and help reduce inflammation. Since inflammation is an immune response that is believed to be a factor in many diseases and conditions, controlling it can have life altering effects for people.

How are THC and CBD different?

THC is psychoactive, meaning it affects consciousness. Things like irritability, hunger and pain are all tied to brain function. THC reduces activity in the hippocampus, the part of the brain where memories are formed/stored). It also inhibits the amygdale, the part where the fight or flight instinct is stored/triggered.
If enough THC is added to the hippocampus, it can lead to a build-up of anxiety. Feelings of paranoia often accompany this negative reaction as the brain tries to deal with the elevated levels of cannabinoids. While no deaths have ever been recorded from weed alone, consuming cannabis does lead to reduced activity in certain parts of the brain.
While reducing brain activity is normally a bad thing, trauma and chemical imbalances can lead to hyperactivity in these brain areas. Conditions like PTSD and anxiety are examples where THC is one of the best treatments available. In fact, the VA recently made strides toward incorporating treatments into the framework of our military.
CBD is a totally different beast. It’s non-psychoactive, meaning it doesn’t affect consciousness directly. Yet it has been shown to have many beneficial properties. Things like swelling, decreased blood flow and seizures are all treatable by CBD.
Besides calming muscle spasms, CBD is able to counteract the psychoactive elements of THC. They have a balancing duality and because of their chemical similarities, it only takes a little acid to transition from THC to CBD and back again. Several companies have successfully synthesized cannabinoids already but it appears that the best effects come from natural plant sources.

How do we use THC and CBD?

Given that our bodies are hard-wired to benefit from cannabinoids, how do we get more? The oldest and most reliable way is to smoke some of the cannabinoid-rich trichomes that cover the cannabis flower. Vaporizing, eating and creating topical creams are also common ways to consume cannabinoids.
Modern extraction techniques exist that can produce almost 100% pure THC from raw plant matter. While this is the most potent/efficient way to consume THC, most commercial products range from 60-80%. Part of the reason lower percentage extracts are more common is the high cost of extremely pure THC or CBD comparatively.
Most people today consume cannabis in the form of food or concentrate to treat a malady or illness. Research has shown THC from smoking weed to be a neural-protector and helps slow/prevent Alzheimer’s. Cannabis can also provide relief to people suffering from neural conditions like Parkinson’s and Cerebral palsy. Patients often find more relief from their tremors, seizures and chronic pain than through other treatments.
Cannabinoids also play a part in the success of traditional cancer treatments like chemo therapy by stimulating appetite, relieving depression and reducing pain. While these benefits may seem minor, the increase in quality of life to these patients is measurable. Over time, the body will adapt to elevated cannabinoid levels so monitoring dosing is important.
Higher concentrations of THC and CBD are often needed for treatment of life threatening illness than can be found in raw cannabis. Over the centuries, this problem has been solved by refining the raw flower into concentrates. Products like BHO, PHO, RSO and CO2 extracts are excellent sources of concentrated THC to modern consumers.

3 Ways to Enhance Your High

Here’s three simple, cheap (mostly free!), and sensible ways to enhance your weed experience.

1. HEMP WICK

Consider this: when you spark up, you’re inhaling everything in the immediate vicinity, including the gas from the lighter. I notice the taste right away, and it can cause a stomachache or a headache if you inhale too much. A Zippo lighter may help cut down on fumes, but if you want to be burning only what’s in the bowl, pick up a bundle of hemp wick. RAW ™ hemp wick seems to be popular and well-reputed.

Immediately, you should taste the difference, and how purely you can experience the unique flavors and aromas of your bud. To use the wick, ignite one end with a flame, then use the burning wick to light your joint/blunt/bowl (like a matchstick, but with no sulphur). Hemp wick is usually made with 100% cotton hemp and a coating of beeswax. The burn is slow, so the rope goes a long way. It’s a very worthwhile and cheap (around $2 a bundle) investment if you want to bring new dimensions to your cannabis experience.

2. HOT WATER

You may think you’re doing your lungs a better favor by using a water pipe over a spoon, but not necessarily. The idea is, the water filters and cools the smoke to be less harsh in the lungs and throat. Partly true! The smoke is cooled to some degree, and I certainly enjoy putting ice cubes in a water pipe to cool it further. However, I recently learned that using hot water pulls out more tar and gunk from your weed than cold water. The effects are a bit like a steam shower–though the smoke is hot, it’s moist, soothing, and better-tasting (if it tastes really rank, clean your bong, dude). Maybe even hot water and a squeeze of lemon juice would be delightful.

One thing I notice with using hot water, less coughing. It’s so much easier to breathe deeply, really feel the parts of my lungs expanding and where I’m not pushing to sit straight enough. The hit ends up being bigger, and the exhale is so much smoother. Speaking of breathing…

3. BREATHE DEEPER

Increase the amount of breaths you take before and after you toke. Cannabis, used properly, opens your lungs, airways, and strengthens the bronchi. Your cough should be deep, with intent, and they’ll pull up anything that shouldn’t be there. Don’t force yourself to cough, though. Your whole experience should be fluid.

Empty and fill your lungs a few times before a hit, trying to take in even more oxygen than the breath before it. Expand your chest, alternate breathing through the nose and mouth. Find a good rhythm for yourself, then at the bottom of an exhale, light your cannabis and inhale (at the same time, if you can manage). Breathe slowly, allowing your lungs to fill with smoke. You’ll be surprised to hear–holding the hit doesn’t actually get you higher. You might, from oxygen deprivation, feel more light-headed. The truth is, the first few seconds are the best, and all you need. After that, the smoke cools, changes flavor, loses the magic.

After you inhale, “hold” for a few seconds (better yet, keep inhaling oxygen after you pull), then breathe out every last bit as evenly as you can. If done with patience and awareness, you should feel high with no adverse affects; no coughing, spluttering, accidental throat burn. With this method, you allow your lungs to be better filters, and you’ll get some deep cleaning done while you chill out.

Ben & Jerry's Releases New Snack for Stoners

Rumors have been swirling that Ben & Jerry’s ice cream is working on a new cannabis-infused product, and they have just announced that they are indeed releasing a new frozen treat… sans cannabis.
The new BRRR-ito is obviously marketed to pot smokers, however. The product is being rolled out on April 20th, sort of the unofficial “National Day of Weed.” The commercial plays upon some (rather degrading) marijuana stereotypes, depicting a crowd of droopy-eyed, brain dead stoners staring at a screen. But I must say that the BRRR-ito itself (which as you might guess is basically ice cream and chocolate wrapped up like a burrito in a waffle cone shell) does look delicious. Check it out here:
 

In an interview with Huff Post Live, founders Ben Cohen and Jerry Greenfield addressed the rumors of a THC-infused treat. They definitely spoke out in favor of legalization, and even seemed keen on the idea of cannabis edibles. But the decision is not up to them. The company has to answer to a board of directors, and prove that the potential profit of a weed-laced ice cream would be greater than the risks – especially when major banks and financial institutions are refusing to do business with cannabis companies.
Still, the new BRRR-ito, and the ad campaign surrounding it, shows that big name companies have their eye on the cannabis market. They can read the writing on the wall: legalization is here to stay, and there is nowhere to go but up.
Who knows what mega brand will jump on the bandwagon next, or what new pot oriented products are yet to be unveiled? But please, no more dumb stoner stereotypes! Cannabis users are more sophisticated than that, and smart companies would do well to recognize that.
