A cooling system developed by Roots Sustainable Agricultural Technologies (ASX: ROO) has increased the yield of dry cannabis flowers by up to 118% at a premium production facility in Southern California.
The Israeli company installed its Root Zone Temperature Optimisation system into a climate-controlled greenhouse owned by luxury cannabis cultivator Canndescent to stabilise the roots of its cannabis plants at an optimal temperature of 21° C.
The recreational and medicinal cannabis producer customises its plant-growing environment by stage and strain, with flowers picked and trimmed by hand. Ambient air temperatures within its greenhouse can reach up to 30° C, with outside temperatures topping 43° C.
In May, Canndescent paid Roots $28,000 to supply and install the RZTO system and achieved increases of between 30% and 118% during the US summer on cannabis strains of 400 and 200 cooled plants respectively utilising wet mattresses and fans within the greenhouse.
The system has helped the producer battle Southern California’s dry desert climate, where temperatures can fluctuate during the summer months between 20° C and 40° C. Extreme heat can have detrimental impacts on cannabis production and crop quality.
