This episode is part of our “What Plants Crave” series, where Dr. Sabeh speaks with growers, researchers, and other experts in other engineers, growers, and manufacturers who work in controlled environment agriculture, to get their insights about the direction of the industry, and of course, what exactly it is that plants crave. This week’s guest is Joe Swartz, Vice President for AmHydro and co-host of the Polygreens podcast with Nick Greens.
