In Canada, certain American States, and around the globe, legal cannabis producers face many challenges: Varying government regulations, high security requirements and too little reliable information on how to cultivate their crops. Growing cannabis has been illegal for so many years that scientific research concerning how to best produce this crop is restricted. A lot of the information concerning how to grow cannabis lacks validation, is clouded in secrecy and is mostly attached to hidden and illegal production facilities of the past.
On the other hand, scientific study has been improving production practices for other crops, including medicinal plants, for years, developing a large body of scientificaly-validated information. With changing government regulations in Canada, and also the many medicinal advantages of cannabis, it is actually time to move the legal cannabis plant production industry in to the world of high-tech laboratories and scientific practices.
We must sift through cannabiscultivationconsulting, while publicly documenting and improving production practices. Evidence-based research can help growers produce more consistent, high-yielding and high-quality products and help inform policy makers as they regulate this industry.
As researchers who study how to produce high-value plants (e.g. medicinal, nutraceutical, edible and ornamental plants) under controlled environments including indoor medical cannabis we feel this will require collaborative research among cannabis growers and researchers. Our lab on the University of Guelph is one of the best on the planet for horticulture research, particularly for controlled-environment plant production. Recently, we have been applying this knowledge to our own collaborations with legal cannabis growers. With legalized recreational cannabis use on the horizon in Canada, more licensed growers are seeking this kind of expertise.
Current state of cannabis production – Growing cannabis can be a lucrative business. Shelling out for legal cannabis in North American medicinal and recreational markets is projected to achieve US$21.6 billion by 2021. In Canada, you can find currently 73 authorized licensed medical cannabis producers, many of them large-scale producers. Using the recreational use and sale of cannabis scheduled for legalization within our country the coming year, it is foreseeable that many more large-scale producers will enter the market.
Root substrates should be tested for pH and electrical conductivity (EC) at the very least every two weeks utilizing a non-destructive pour-through technique. Graph these results. Youll understand the trends that develop over your crops growth stages. Also, occasionally track this data every several hours after a fertilization. Youll be surprised how rapidly the plant requires fertilizer in just twenty four hours. Adjust fertilization accordingly to maintain your required pH and EC, based on crop stage and your knowledge of the cultivar. The fertilization schedule will be different based on sunlight and temperature in a greenhouse or outdoor setting, and can maintain more stability in controlled environments.
It is possible to determine a powerful, data-based comprehension of your crops nutrient status by building a graph that compares laboratory testing outcomes for individual nutrient levels overlaid with your routine pour-through tests. Substrate testing by an external lab is pricey, with tissue testing much more so. For cost effectiveness, track soil and tissue nutrient content regularly for your first couple of crops in a new grow system, then annually following that. Tissue and soil samples should be taken every jmvgih weeks, minimum. Your end goal is to make a hospital chart hanging nearby the crop for the team to make reference to, with actual measurements plotted with time and desired ranges clearly indicated. This can effectively facilitate consistent nutrition across crops and multiple growers, as well as in multiple facilities.
In the past, indoor cannabis production was largely confined to smaller-scale operations. Under these conditions, growers accumulated enormous levels of knowledge and experience. But much was kept as trade secrets and many still needs to be scientifically validated. Even during todays modern medicinal cannabis production facilities, growers tend to be reliant on online forums so-called grow guides and advice from salespeople for information about crop production. Without the proper training, it could be hard to tell fact from fiction.
