![]() The control treatment was factored into the design of a follow-on study involving ~4000 clones at PVP. It is important to note that the PVP facility has been using the control treatment for quite some time and the results from the studyshows that there is tremendous opportunity to improve PVP baseline production performance. For all parameters studied, the POR control treatment did not come out first of the six treatments applied. Of the six treatments, the company’s RMD chemistry was the fastest to “first root” and had the highest overall dry weight per plant post-harvest. ![]() The six nutrient treatment conditions used involved individual and combinations of the company’s RMD chemistry, an algae-based treatment, an ozone water-based treatment, as well as the process of record (POR) production nutrient method involving commercial chemistries. ![]() The primary goal of the study was to allow for increased time during the plant “Veg” conditions to enable increased production biomass yield at PVP post-harvest and reduce overall cultivation production cycle times. The experiment was co-designed by the principal investigators to evaluate which nutrient treatment method could potentially “first root” (first visible rooting outside of the clone media ) and “fully root” (sufficient visible roots to allow for successful transplant to the vegetative stage “Veg”) the fastest. Thirteen replica clones of each unique treatment condition and strain were processed to aid in achieving statistical significance. In a time-paired experiment six different nutrient treatment conditions were applied during the cloning process. ![]() The study was done at Pecos Valley Production (PVP, a commercial cannabis cultivation and harvesting company in southern New Mexico). In the study, approximately 500 clones were grown from five different strains of cannabis “mother” plants. Five different nutrient treatments were evaluated along with a control group. This paper provides results from a study of the effects from different nutrient treatments used during the cloning process of a cannabis plant. ![]()
