Plant temperature optimisation specialist Roots Sustainable Agricultural Technologies Limited (ASX:ROO) says the latest tests of its unique technology, has seen a 40% improvement of a harvest yield of cannabis.
The testing of its Root Zone Temperature Optimisation (RZTO) technology was undertaken at growing facilities of Ivo Lopez of Mendocino Natural Farms in Northern California.
Ivo Lopez, the Head Grower at Mendocino Natural Farms, said that in addition to increased yield, the projected number of harvests per year at the facility is predicted to double through a 30% reduction in annual growth cycles.
Using Roots’ upgraded RZTO system, the roots of the cannabis crops were heated at night to remain at a stable range of approximately 23 degrees centigrade, despite air temperatures in the hoop house frequently dropping below 10 degrees centigrade.
Root Zone Temperature Optimisation (RZTO) technology increased the harvest yield of cannabis by 40% compared to previous years,” Mr Lopez said.
Roots’ CEO, Dr Sharon Devir said that following the initial sale in April 2019, the installation was completed during early spring with growing taking place throughout summer amid severe temperature fluctuations. Extreme temperatures significantly impact cannabis harvest production and crop quality.
“We are extremely satisfied with the harvest results seen on cannabis. The results have validated the multiple benefits our two-in-one heating and cooling technology can provide to high worth crops by rapidly improving growing cycles and increasing resistance to extreme weather conditions,” Dr Devir said.
“Based on increased production and quality, RZTO technology will allow cannabis growers to generate an attractive and expeditious return on investment compared to similar cooling and heating technologies. The results will allow Roots to build tangible case studies which can be leveraged to secure further sales and complement the company’s sales efforts in the North American cannabis market.”
Dr Devir said the results are consistent with similar results from other North American and Israeli cannabis growers who bought the RZTO system and reaffirm Roots’ sales approach into North America.
