Cannabis, a Hyper-Accumulator


Edited: Sep 6, 2018

Hyper-accumulation is the massive accumulation of certain minerals that occurs in certain plants when compared to other plants. Marijuana hyper-accumulates certain heavy metals including lead, cadmium, magnesium, copper, chromium, and cobalt. Considering that marijuana is most often grown for medicinal/food purposes, what do you all think about creating a soil mixture list that contains the least amount of these heavy metals that are potentially a health hazard? Here is a study for reference: Also, here is a link to an interesting video about garlic's capability to cure mild to moderate lead poisoning and chelate other heavy metals out of our systems (or more specifically, rats systems in the studies mentioned): Supposedly eating just about anything reduces lead absorption by 90%, so perhaps none of these precautions are necessary. There are many ways to lower lead levels in the blood in general. What do you all think? Should growers be taking this into mind and avoiding amendments/products with excessively high levels of heavy metals in order to avoid growing plants with hyper-accumulations of metals like lead and cadmium?

If you feel your soil or amendments are contaminated with heavy metals, you can grow a cover crop like hemp to clean up the soil before you grow food or medicine.

@Chef thank you for your response. That's great advice and just about covers this post. My only question left would be about additions to soil like amendments and compost etc, continuing the soil cycle for organic no-till. Here's what I currently do for amending soil for the plants in my garden: -organic compost (probably 1-1-1) -kelp (1-0-2) -rock phosphate (0-3-0) -Black insect frass (4-2-2) -Add teas during waterings. Always add powdered soluble yucca and amino acids, the two best bio-stimulants for high brix I personally think!!! I avoid amendments with excessive heavy metals and sus contents, such as bone meal, blood meal, anything with sewage or human or an unclear animal product source, or any of that Monsanto GMO stuff etc... Don't get me wrong tho, I used bone meal for my other plants, up until the stuff got stolen from my outside garden. Fortunately the indoor garden is locked up. Got plants with off the scale brix with bone meal for Ca and P. I just worry about cannabis since it has the particular capacity to hyper-accumulate and it's medicine you know and we are always adding stuff and organics in soil is kind of a new territory, a newer developing science. I donno. I'm all about getting the highest quality while benefiting the environment. Just seeking out the premo info in attempt to grow such for myself and others :D

  • I created a social site that focuses on marijuana... Pot Swap Club, were people are able to trade marijuana and more. I created it last year, however I had some health problems and other issues and had to put the site on hold, but now i'm back in action. I just added forums and could use knowledgeable people , if interested, please watch the short video and visit the site... To our success in life "What we tell ourselves, our brain believes"
  • Hi all. This is a message to Chef's family who I assume might have control over this website now. Please inform everyone of the status of the website. I would appreciate being able to come back and post, but perhaps it is time to share my research with another knowledge data base. I currently have my research saved from this website but would recommend everyone save any posts that are of particular interest to them as well in case the site is suddenly shut down.
  • Hi all. Below is a recipe for a homemade organic pro-mix taken from SF Gate. I know Chef has passed but I think this is still an excellent forum to gather on and spread research with. I do think someone should comment on if this web page will exist for long though as well just in case so this valuable research is not deleted! I have back ups just in case but I'll make a seperate post for that. Onto the pro-mix recipe: 1/3 peat moss 1/3 perlite 1/3 organic gardening soil 1/4 cup garden lime per gallon of mix I have tried it and it works. Be careful if you have hard water, you will need to add intermediate chelators (AKA L-Amino Acids) to chelate the calcium, magnesium, etc in your water to prevent transpiration issues etc general salt issues that occur with mixing hard water and this fairly sweet and calcium and magnesium rich soil mix. I recommend going easy on the dolomite lime in general and also go easy on the peat moss, peaty soil is known to compact. If you are gonna be moving plants in pots add more perlite than peat moss because this will help with transpiration issues that come from compaction when moving potted plants around. You'll notice how good this mix smells and works for plants! You'll get very fast growing plants because this mix is focused on high porosity for a very high rate of transpiration and therefore plant mass production! Also note that this mix only feeds plants for a couple weeks and then you will need to add some salts for the plant and soil health. Adding a bit of organic matter to the soil eventually will be a good idea as well to continue feeding your organic base in the soil. I personally have a food web with springtails being consumed by a certain antonymous fungi in my soil I try to keep going. The springtails don't leave the pot and the fungi and springtails provide a ton of nitrogen to the plant, potentially CO2 as well! This cycle has successfully infected all the pots in my house interestingly. Sources: SF Gate Guide for peat moss pH balancing: Peat moss to perlite ratio (Also SF Gate): SF Gate's article on the disadvantages of soil-less media (similar to this growing medium (pro-mix) minus the organic gardening soil): SF Gate article on composition of potting soil (good place to start to understand potting soils which are often replaced by soil-less pro-mixes). Also ratios of stuff: On the springtail and fungi note, that is harder to source. The certain springtail eating and red hued mushroom producing fungi comes from Host Defence's Myco-Blend all purpose microbial and biostimulant inoculant and I think the springtails followed me via transporting the same compost over a long period of time. On the transpiration topic: Dr. B.C. Wolverton's book "How to Grow Fresh Air" explains that there is an equation that dictates how much air a plant is filtering dependent upon how much mass the plant produces. This has a lot to do w/ the soil medium. High porosity soil makes for the fastest mass production in plants. PS. If you have your own high porosity pro-mix or something similar please post it here. Of particular interest are environmentally friendly mixes, which the above mentioned mix is not due to the unsustainable peat moss component. Coco coir can be used to replace it (and is more environmentally friendly) but then potassium salts should be added at some point although I am less experienced with that mix so I don't know how soon potassium would be essential. I imagine co co coir may cause issues w/ pH because it may not be super acidic and so dolomite lime may need to be adjusted to lesser quantity per gallon. Also this mix may have too much calcium and magnesium due to coco coir and dolomite lime having so much of these elements. Maybe it'd be fine though. A good pH, texture, and an organic base, and magical things can happen with any soil mix basically.
