Presentation description:

There are a number of technologies on the market today that enable greenhouse and vertical farm producers to enrich water with different gases. These technologies can be used to supplement oxygen levels that drop in recirculated water systems, reduce build-up of pathogens in the water system, and improve plant health. This webinar will host experts on this topic to inform and educate producers on some of the uses and benefits of these technologies. You will hear from Dr. Thomas Graham, assistant professor at the University of Guelph, on the differences between microbubble and nanobubble technology, and Warren Russell, chief commercial officer of Moleaer, will discuss the science behind Moleaer’s products and services.
