University of Guelph researchers have published what is believed to be the first scientific paper in North America on improving medicinal cannabis plant production, helping move the industry into the realm of high-tech laboratories and evidence-based practices.
“Growing marijuana has been illegal for so many years that there has been hardly any scientific research up until this point on how to produce this crop,” said Youbin Zheng. “There has been no science guiding this industry.”
Zheng, along with Mike Dixon and PhD student Deron Caplan, investigated optimal fertilizer rates and soilless growing substrates required to grow cannabis plants that have higher amounts of medicinal components and greater yield.
The study, which was funded in part by Natural Sciences and Engineering Research Council of Canada, was recently published in the journal HortScience.
It is the first of a series of U of G studies investigating ideal horticultural practices for indoor cannabis production.
