Roots Sustainable Agricultural Technologies Limited advised that it has successfully registered a design patent for the Company's revolutionary heat exchange stub in Australia. The heat exchange stub is designed to be inserted into the tops of plant's pots and grow bags to significantly simplify working procedures and lower the installation cost associated with Roots' Root Zone Temperature Optimization (RTZO) technology. RTZO technology optimizes plant physiology for increased growth, productivity and quality by stabilizing the plant's root zone temperature year around. Optimal Root zone temperatures is known to be the most influential parameter in plant's physiology besides water. The Company's heat exchange stub enables the mobility of pots and grow bags during the growing cycle. Chains of stubs with insulated pipes in-between can be used for row installations. The solution caters primarily to the nursery, greenhouse and cannabis markets and has been successfully tested to Roots' research hub and among Cannabis growers in Israel. Roots completed the registration on 10 January 2020 and were awarded the patent shortly afterwards. The patent was approved by IP Australia. IP Australia is an agency of the Department of Industry, Innovation and Science. It administers intellectual property rights and legislation relating to patents, trademarks registered designs and plant breeder's rights in Australia. The design patent will protect intellectual property developed and owned by Roots, while it sells the solution internationally.
