Horticultural science researchers published their weed growing study in HortScience. A history in the making event, it is too. Because it’s the first such research paper ever published in North America. Naturally, this study took place in Canada where they’ve made more progress in ending cannabis prohibition than in the US.


Still, scientists at Ontario’s University of Guelph aren’t the only ones to dive into removing more of the taint and shadows surrounding the herb. It seems this is a fall of firsts. While accredited Canadian scientists work on perfecting weed growing, across Lake Superior, Northern Michigan University launched their Medicinal Plant Chemistry program in September. It’s a marijuana-focused degree dealing with the medicinal compounds in such plants and their extracts. However, it’s  a seriously in-depth and rigorous Bachelor of Science, not a fluff class.

NMU students will not actually do any weed growing. Even so, this is the first degree offered in the United States that studies marijuana and its complex beneficial compounds. With medical marijuana legalized in 29 states and a growing demand for specialists, other schools will likely follow suit.

As one of the top schools for horticultural research, it’s no big surprise that Professors Youbin Zheng and Mike Dixon enjoyed the honor of breaking the ice. They’ve already been studying medical cannabis for several years. Plus U of G has state of the art facilities with cutting-edge technology in place. Suspecting the big pharmaceutical firms paid for this? Nope. Funding for their weed growing work came from established Canadian medical marijuana production companies and the Natural Sciences and Engineering Research Council of Canada. The quest: find the secrets to perfecting weed growing for the biggest user benefits.


Not for recreational users. This study focused on identifying the organic nutrient level and growth media needed to perfect vegetative stage medical marijuana production. Specifically, weed growing practices for optimizing THC and cannabidiol at harvest stage. And the paper published in HortScience in mid-October gives those specifics in detail. Unlike many journal papers, this one has affordable access. Just $10 gives you access to “Optimal Rate of Organic Fertilizer during the Vegetative-stage for Cannabis Grown in Two Coir-based Substrates” for a day.

This journal paper is the first in a series. And they have a second paper scheduled for publishing in HortScience soon. It deals with the specifics for lighting and irrigation practices that deliver the highest yielding plants, rich in CBD and THC.

Proposed changes in Canadian legislation will only increase the number of licensed growers looking for the same level of control. And with the ever-increasing number of Americans in favor of legalization, weed growing businesses for medical and recreational use will grow there too. Science journals publishing accredited scientific studies, and Bachelor of Science degrees in weed growing and herbal compounds changes everything.
