Many small farms are implementing greenhouse hydroponic systems. Perhaps the most challenging aspect of crop management for smaller growers is the control of water and nutrient delivery in a soilless media system. This six-page fact sheet focuses on relatively inexpensive strategies to help small growers know both when to start irrigation events and how long to run a single event when growing in soilless media. Written by Robert C. Hochmuth, Natalie B. Parkell, Wanda L. Laughlin, and Sean C. Rider, and published by the Horticultural Sciences Department.
