Root zone cooling technology provides often 40% more cannabis yield in high-tech greenhouse

There are many benefits associated with controlling the temperature of the root zone. A healthy plant with a consistently optimal root zone temperature will be indeed more resistant to extreme temperature fluctuations in the canopy area, pest attacks, nutrient deficiency and fertilizer deficiency. If the root zone temperature goes off the optimal range, the plant would experience a reduction in micro-organism and micro-element activity, and would suffer from a lack of nutrients such as nitrogen, phosphorus, as well as micro elements such as iron. Additionally, the growth might be slower or could stop completely, causing poorer yields and quality.

That’s why it is of the utmost importance to give the root zone the optimal temperature that allows the plant to express its full genetic potential. “When there is a hot environment, and you cool the root zone, the nutrient uptake rate is semi optimal or optimal,” Mark Fishman an Agronomist with Roots explains. “On top of that, cooling substrates under hot air temperature ensures oxygen availability, which impacts the plants growth and productivity. On the other hand, if you heat the root zone when the environment is cold, the plant growth is not stunned by the cold air or soil temperature, which can make you lose 2-3 hours per day in plant growth and photosynthesis.” That’s where the Roots’ Root Zone Temperature Optimization system comes into play.
