I posted an article regarding Cannabis Hyperemesis Syndrome recently that suggested that pesticides used in the growing of our cannabis could potentially be the cause of CHS. Pesticides, specifically NEEM, are often used to combat spider mites during growing. Considered 'organic' this product was made for fruits and vegetables and is considered 'safe' for consumption. But no testing has been done regarding inhalation of this product. More on pesticide use in our product....

Ignorance in bloom: Cannabis cultivation and the casual use of illegal poison
Two-spotted spider mites are the arch enemy of cannabis growers everywhere. Cannabis growers are not generally a hateful bunch, but that changes when these minuscule pests come up in conversation.

Pests will harm your plants, effecting your yield and quality. If left unchecked, many can lower the quality of the final product beyond the point of use. Spider mites are one of the few common pests that can result in complete crop failure.

Spider mites are all over the place. They are common pests on a surprisingly wide range of plants, including tomatoes, squash, blackberries, strawberries, hollies, roses, azaleas, and chrysanthemums.

As a result, they are carried into grow rooms on clothing, pets, and supplies. They also tend to find their way in to indoor gardens and greenhouses from outside when the weather cools in the fall.

One big reason that growers despise these tiny plant killers is the fact that they are very resilient. It requires multiple treatments to get rid of them once you have them, and they become resistant to pesticides quickly.

These are not the only pests that a grower has to contend with either. Powdery mildew, root aphids, thrips, russet mites, and broad mites can all target cannabis. The path that is chosen in finding a long-term pest control solution depends on the grower’s philosophical views on how to garden.

It can be handled in two ways. One is to use a variety of preventative measures, and treatment only when absolutely necessary, which is known in horticulture as integrated pest management, or IPM.

The other, which is much more common among large illicit commercial producers, is to use more poisonous pesticides, and more of them, even when it is not evident you have pests.

Readily Available: Easy Access to Highly Toxic Pesticides
I was very young when I killed my first cannabis plant.

I was a teenager, and figured I could just stick a plant in my closet, and I would magically have a big bag of top-notch smoke in a couple of months.

As you might expect, I was mistaken. After over-watering, then under-watering, then messing up the light cycle, the plant finally got infested with bugs and died.

Of course, I was dismayed. I did not give up, though, and I kept trying. Eventually I would have a measure of success. Over time, I would also have many run-ins with my old nemesis, the spider mite.

When I was a bit older, I had graduated to a small four light basement grow, and I got mites again. This time, I had learned to identify them early, so strolled down to my friendly neighbourhood hydroponics store. They had recommended strange-coloured GH three-part feed, so I asked them to recommend something to kill mites.

Instead of pointing to a product on one of the shelves, the proprietor stepped into the back, and emerged with an un-labelled brown glass eye dropper bottle. He pulled out a sheet of sticker labels, wrote the dilution rate on it, told me that this stuff would kill anything, and asked me for $200.

At the time, I knew no better, so I paid him, and asked him if there was anything I should know. He said that I should probably wear a mask and gloves. I didn’t bother.

The product he sold me, while still in my teens, is known as Avid, and it is the most common pesticide used in the commercial cultivation of cannabis. It is made by Syngenta, one of the biggest poison manufacturers in the world, and the active ingredient is abamectin. It has been approved for a bunch of different food crops, despite that fact that human side effects identified in peer reviewed studies include low sperm maturity.

Avid is very toxic, but it is just one of many options. Meltatox, Floramite, Forbid, Eagle 20, Nova 40, and TetraSan are easily accessible at either brick and mortar shops or online. If you have bought and smoked cannabis, the chances are that you have inhaled the residues of more than one item on this list.

While some of these are approved for certain food crops, there are not that many smoked crops being farmed. There is tobacco, but it is practically dripping in pesticides, being the sixth most heavily sprayed crop in North America. Studies on the inhalation of smoked pesticides in cannabis are starting to be seen, with the expected result that pesticides can efficiently transfer from bud to lungs through smoke.

The fact that these highly regulated and restricted toxins are so readily available comes as a surprise to many outside the cannabis community.

The fact that a segment of the industry feels entitled to poison patients for profit is offensive to many inside the cannabis community.

Greed and Ignorance: Unethical Disobedience
“That is what everyone uses. Who cares if it is illegal? This is all illegal.”

These are words that I have heard many times over the years as I tried to find other solutions for pest control. Sometimes, these same people would later spout off about civil disobedience, and how they were part of the positive change that was coming.

Those who are truly civilly disobedient do care that it is illegal. Is it unjust to punish people for growing and using a plant? If the answer is yes, then I will intentionally break that law.

Is it unjust to prohibit growers from making more money at the expense of the consumers’ health?

Anyone who answers yes to that question, and knowingly acts this way, is not acting civilly.

There is nothing civil about poison.

Outdoor growers are kind of in a pickle.

Inside, clean rooms are the first defense.

Their natural predator the common house centipede? Most effective spider mite killers I've ever seen.

Most tents have small openings no matter what you do, and require a dark room or blackout curtain around them anyway. If you have even one centipede in the same ROOM as the tent?

Spider mite apocalypse.

The research on neem assumes neem is sprayed on buds, something a knowledgable grower would not do. Like a lot of organic growers I use it on plants up to flowering. Once flowering starts the neem stops. And neem itself is used in toothpaste, (safe to eat) so the assumption is we are smoking or vaping neem oil.

I think my best pesticide is my worms. The castings are teaming with life. Lots of shredder type mites and preditor mites. Some you can see by eye and some you can't. Spider mites really don't have a chance around here.

As long as I'm at it I keep my worm farm in my flower room, and a side benefit is the process of them doing what they do and decomposing organic materials gives off co2. So they give me pest control, fertilizer, and co2. What's not to love, lol.

I feed the worms mj leaves, and bed them in compost I make outdoors of leaves and garden/table scraps. The mj leaves I pre digest, or ferment in water. So the water becomes a plant extract used as a fertilizer, and the fermented leaves are worm food.

I wasn't quite sure where to put this, so I broadened the scope of this thread to include contaminants as well as pesticides. This article sort of opened my eyes to something I hadn't thought of prior; contaminated soil. It probably doesn't effect indoor grown cannabis, but could potentially be a factor in any cannabis grown outdoors.

How to Test for Heavy Metals in Cannabis

Cannabis collects heavy metals. It “absorbs heavy metals from the soil, water and air,” says Bob Clifford, general manager at Shimadzu Scientific Instruments. These elements—arsenic, cadmium, lead, mercury and others—can trigger a range of health problems, including cancer and heart disease. Although cannabis for human consumption or smoking should be as free from heavy metal contamination as possible, that’s not always the case. When Sammy Hagar wrote “sparks fly in the middle of the night,” little did he know that this line could describe not just heavy-metal music, but the concerns of testing of cannabis for these elements.

Today’s ‘sparks’ fly around the need and necessary extent of testing cannabis for heavy metals. “Heavy-metal contamination will vary from farm to farm and different strains will have different uptake rates of metals, thus the importance of testing,” Clifford explains.

Regardless of where cannabis comes from, it can include heavy metals. “All agricultural products, including cannabis, contain some amount of heavy metals,” says GenTech Scientific. “The use of things such as fertilizers and pesticides in agricultural applications increase the abundance of these metals in soils and water.”

Beyond coming from natural sources and agricultural methods, heavy metals can infiltrate cannabis-based products in other ways. As an example, GenTech Scientific notes: “Contamination can also occur during the processing of cannabis.”

Despite the wide range of potential sources of heavy metals, it is not inevitable that every cannabis sample includes these elements—at least not at high levels. “With the correct atmosphere, clean soil and water, and limited use of pesticides and fertilizers, you can keep your levels below the acceptable safe limit,” according to GenTech Scientific. Nonetheless, this company adds, “It is important for growers to monitor the levels to ensure their products are in compliance with their state’s regulatory guidelines.” And those can vary considerably.


Where regulators do require testing cannabis for heavy metals, the list usually includes arsenic, cadmium, lead and mercury. “Other states, like Maryland, include additional elements to be tested for such as barium, chromium, selenium and silver,” Clifford says.

Testing tools

Cannabis can be tested for heavy metals in many ways, such as various forms of atomic spectrometry, including atomic absorption (AA), inductively coupled plasma optical emission spectroscopy (ICP-OES) and inductively coupled plasma mass spectrometry (ICP-MS). “For AA, the method used would have to be the more sensitive graphite furnace atomic absorption—GFAA—since the flame AA method would not be sensitive enough for most elements,” Clifford explains. “Also, mercury must be measured by a method called cold vapor atomic absorption spectroscopy—CVAAS—due to poor sensitivity by AA.”

In general, flame techniques can measure elements at low parts per million, and GFAA goes down to low parts per billion. “Also, the AA method usually measures one element at a time,” Clifford says. “ICP and ICP-MS are techniques capable of measuring multiple elements simultaneously.” Nonetheless, using ICP to test cannabis for heavy metals, often requires a way to enhance its sensitivity, such as introducing the sample with an ultrasonic nebulizer (USN). “The USN can increase sensitivity up to a factor of 10,” Clifford says.

From Aeos Labs, analytical chemist Anya Engen says, “ICP-MS offers the best sensitivity and is the method used in our lab.” She adds, “The FDA and United States Pharmacopeia have standardized methods for heavy-metals analysis, which are very useful resources in the fledgling cannabis-testing industry, where regulation is slow to catch up.”

To test for arsenic, scientists often need special sample preparation, such as liquid chromatography (LC), because arsenic can be in inorganic or organic forms. The inorganic form is more toxic. “If one wants to test for the different forms, LC-ICP-MS is utilized to separate and detect the different compounds,” Clifford says. “States currently only require total arsenic, so speciation of this compound is not required.”

Tomorrow’s testing

Not all regulators even require heavy-metals testing for cannabis at the moment. “We test for heavy metals in the USA’s food supply system, enforced by FDA and USDA, so why would we not test for other consumed products like cannabis, especially when involving immune-compromised patients?” Clifford asks. “There needs to be federal oversight of testing for heavy metals, as well as pesticides, residual solvents, mycotoxins and other contaminates so testing is harmonized throughout the United States.”

When asked if any testing improvements would be useful, Engen says, “Measuring heavy-metal levels in the soil and water where cannabis is grown and correlating the data to cannabis-generated data would be helpful in illustrating an overview of possible contamination sources.” She adds, “Being in Hawaii with an active volcano, the heavy metals produced and dispersed by the volcano is a possible source of contamination in Hawaii-grown cannabis.”

Without testing cannabis for heavy metals, sparks could fly from more than guitars as customers insist increasingly on safe, tested products.

So 'bugs in the grow' are one of my biggest concerns with growing. I've heard horror stories about spider mites ruining a crop. We've discussed NEEM as an option for control and it's safety. But it would be nice to find an option that doesn't use any form of sprayed on substance.

Tooling around the net I stumbled on this.... has anyone tried this method of control? And how about ladybugs?

The satchel releases preditors mites, something that occurs naturally in high end compost. Nothing wrong using them, but a balanced Eco system is your best bet. Ladybugs rarely stay long enough to help much.

Marijuana growing covers 3 stages. Seedlings/cuttings/clones, vegging plants, flowering plants. If you take care during the first two stages the flowering period will be fine. First carefully inspect shorties, especially those not from your own garden. Until theyre rooted spraying can be problematic, (cuts breath and feed through the leaves until roots get started) but you can gently use soapy water on mites. Second is a regular neem oil spraying program of weekly sprays in normal conditions and every 3 days during an active infestation. That program has never let me down. Sooner or later everyone gets mites, but not everyone deals with them properly. Mentally just assume you have them, if that helps.

Once flowering has started your options are more limited. Whatever you spray on flowers will end up on your buds. There are safe things that you can do, but nothing beats a regular program earlier. And you really should be anal about your program. And yes loosing an entire garden is disheartening.

Way cool!

As an old hippy I've used Dr B products for many years.

A small container was my all in one backpacking soap for me and for clothes. Great for turning sweat soaked clothes into minty fresh clothes. You can even brush your teeth with it.

And I use Dr b's peppermint soap as an emulsifier with neem oil as a pre flower bug deterrent.

I buy it by the gallon.
I love Dr. Bronner's soap, @Shredder. Is peppermint best for the garden? I've always used peppermint, but my bottle was dumped into my dishwasher and needs to be replaced. I wasn't sure if I should buy peppermint or lavender, or if it mattered. That is, is it just the soap we want, or is peppermint part of the repellant properties we are after? I figure the only way to get over losing four large bottles of the stuff is to buy more.
I'm excited that they have joined up with Flow Kana, and will keep an eye out to see how long it takes to show up at my local dispensary.

Peppermint and lavender both work by themselves for a bug deterrent or better yet as an emulsifier for neem oil. After spraying my room smells great for hours. I use neem oil, dr B's soap, and a little liquid silica in my sprays. Sometimes I might add a 1/4 tsp per gallon of 200x aloe vera powder, as a growth/health stimulator.

I spray at lights out, and when they come back on, it's like the plants are all smiling at me.

Btw lavender,and peppermint are both part of the mint family. And bugs don't like mint.

Using neem in pre flower works great on mites. I havnt had mites in flower in years. But if I did, my go to's are mint teas. I soak lavender flowers in water, strain and spray the plants. Another mint family plant that might be easier to get is cylantro. I put in a blender with water, then strain and use the water to spray with. I wouldn't use any soap in a spray in flower. Even if you could take the smell and taste soap melts oil glands. The mint teas while gentle won't stop every mite in a heavy infestation, but they will get you to a harvest in all but the very worst infestations. And they don't leave any harmful chemicals behind.

Thank you @Shredder. I grow mint ( in pots- we learned the hard way about mint taking over the yard) lavender and cilantro, so it's easy to come by. White cabbage moths are my nemesis. You never know what new blight is next in a garden, but I'm banking on cabbage moths. That's more for Bt, and is more of a problem in flower. Your method using herbs and a blender will be my preflower method. Thank you for your help. I'm wanting to do this clean and healthy. I should start An Idiots Outdoor Grow thread so I can get through this crop. We did fine last year, but we had to keep reminding ourselves it was a salvage crop so we didn't despair. I'm excited about this new start.

A couple of years ago, on my first grow, something was chewing on leaves. Not wanting to include toxins I did a bunch of goole-fu and found cinnamon water - a tablespoon of cinnamon, boiled in a gallon of water, strained, then sprayed on plants. Bugs would land and immediately take off again, and chewing stopped. Will try some lavender next as we have quite a bit growing in the yard...

Did you guys ever read the ingredients on Dr Bonners soaps? Right in the middle of the ingredients (at least here in Canadia) some of their scented varieties include Cannabis Sativa (Hemp/Chanvre) Seed Oil (chanvre is french for hemp, apparently)...

For my ornamentals (Hostas, roses, rudbeckia, Russian sage, etc,... ) and vegetables I also use DR. B's soap mixed with cayenne. I add two table spoons of cayenne, one cup of Dr.B's to a two gallon sprayer and fill with water. Actually, I do that reversed. Add the water first, then the soap. And I have had little trouble with insects.
Companion planting also helps Marigolds, lavender, catnip and mints planted around other plants will help with some insects.

A little off topic, but I add cayenne to my birdseed and it helps with squirrels but doesn't hurt or stop the birds from eating the seed.

More off topic, vinegar is a great non toxic weed killer. Keep in mind vinegar is total kill, so spot treating might be more useful in some instances.

I'm not sure if this product is only available (and used) in Canada... but thought it would be useful info. Do any of our U.S. growers use fungi to fight mold?


CANNABIS SPRAYS EXPLORED: RESPONSE PLAN FOR ALLERGENS


We previously discussed some benefits and problems surrounding the use of Predatory Fungi like Prestop when growing cannabis– a ‘fight fire with fire’ form of defence against moulds and mildew in the agriculture industry.

If they are sprayed during flowering, the beneficial mould can stick to stems that a bud will eventually grow around – trapping the pesticide deep inside your nugs. Only light will destroy these microorganisms. Once trapped inside a flower no amount of time or flushing will help. You cannot push out or dilute fungus. Producers can dramatically raise the colony-forming units (CFUs) without ever failing any of Health Canada‘s testing, as long as the mould they trap in your cannabis has been “approved.” Despite an obscure allowance, producers simply should not resort to these damaging means simply to increase crop yield, or else it would be the epitome of quantity over quality.

What does residual mould mean for your health?
Several types of moulds are available to Canadian Cannabis growers, some Genetically Modified while others are natural.

Here, we discuss the certified organic spray Prestop.

Its active ingredient, Gliocladium Catenulatum J1446, has been deemed safe for your food in a normal residual quantity. Like all moulds, however, this strain can lead to respiratory, skin, and eye irritation in acute amounts. In sensitive individuals, it can bring on allergic reactions and symptoms such as wheezing and coughing.

Comparatively though, the impact is far more benign than an attack from some unwarranted, carcinogenic fungi that could be invading all sorts of organic material. The amount of Prestop used in normal conditions should not cause adverse symptoms, but that conclusion was made before its approval for Cannabis. Unlike your skin and stomach, our lungs are sensitive and burning the mould has never been studied.

Most fungi will attack plants, reducing their photosynthesis which can damage crop yield. Using a beneficial mould that is known to feed on plants without damaging them can dominate that territory without negative recourse. Other mildew will not survive when forced to compete with this introduced organism. Prestop ultimately allows you to control the plants’ myco-environment.

Unfortunately for those that enjoy black coffee, Prestop is more of a cappuccino.

A blend of additives carry the fungi as it’s applied over the vegetating or even budding plants. This pesticide can contain several mixtures which will always be 40% Gliocadium cells and 20% sucrose. The other 40% can be starch, Kaolin Clay, lignin, and carboxymethylcellulose (CMC); or possibly, 40% skim milk powder.

I do not mean to put a strong moral under a shadow, but intentionally using milk for cannabis has a bigger concern than manipulating the sentient beings in the dairy industry for medicine and recreation.

Unlike lactic acid, milk allergies may be a cause for concern when any quantity of powdered milk is lathered onto our food or herbs.

These reactions are rare and typically affect children- however, they can occur. Especially considering sensitive medical patients are using those medicinal herbs.

If you demand immediate medical attention, in any case, Health Canada does not have an emergency line. Please contact and use the appropriate emergency services.

In the event of an adverse reaction to legal Canadian cannabis please do follow up with Health Canada.

I do not mean to put a strong moral under a shadow, but intentionally using milk for cannabis has a bigger concern than manipulating the sentient beings in the dairy industry for medicine and recreation.

Unlike lactic acid, milk allergies may be a cause for concern when any quantity of powdered milk is lathered onto our food or herbs.

These reactions are rare and typically affect children- however, they can occur. Especially considering sensitive medical patients are using those medicinal herbs.

If you demand immediate medical attention, in any case, Health Canada does not have an emergency line. Please contact and use the appropriate emergency services.

In the event of an adverse reaction to legal Canadian cannabis please do follow up with Health Canada.

Things to keep in mind
For all other general complaints use cannabis@canada.ca, as well as the contact line to the Licensed Producer and the provincial cannabis distributor the cannabis originated from.

In the event of a serious adverse reaction, carefully keep all contents of the container. Do not follow through with a recall, do not receive your refund. Collect receipts and record the events and data. Finally, contact a professional legal assistant, such as a reputable pro-cannabis lawyer if the incident is within reason.

You can make a beneficial bacteria (lactobacillus) or lacto B fairly easily at home using rice water and milk. It's the most common bacteria and can out compete most fungi or other bacterias. Its actually in and on us. It's also easy to use as a spray. Google it if interested.

But most horticulturists consider mold an environmental problem. Mold spores are everywhere, but if you don't give them an opening they won't thrive. air movement and humidity are the biggies.

Both neem oil and liquid silica can help with mold as well. But I wouldn't use either in flower, but if used earlier, it can have lasting effects. A ten percent milk spray can help too, by raising the ph. Mold wont grow in a ph higher than 7. Baking powder is in popular commercial sprays for this reason.

And don't overlook organic compost to help with harmful molds. Good compost has bacterial and fungal armies that can out compete harmfully fungi as well.
