What is the best LED light recipe?

As a result of his postdoctoral research tenure at NASA Kennedy Space Center, Mickens has published two manuscripts on the effect of light quality on ‘Outredgeous’ red romaine lettuce and “Rubi F1’ red pak choi, a Chinese cabbage. It was found that various combination of colors, or “light recipes” could be used to manipulate plant […]

Pythium root rot on hydroponically grown basil and spinach

by Neil Mattson for eGro (https://e-gro.org/pdf/E301.pdf) Waterborne diseases that infect roots are a common production issue in hydroponic production. Several species of the water mold, Pythium, attack greenhouse crops. Basil and spinach are susceptible to economically devastating levels of Pythium root infection in hydroponics. In this article we will present symptoms of Pythium infection and management strategies. […]
