Dr. Russell Sharp explores lamb's lettuce (Valerianella locusta) as an underrated hydroponic crop, highlighting its unique botanical lineage, high nutrient content, and suitability for cold or unheated systems where traditional lettuce and other warm crops struggle.
The episode covers practical benefits—reduced soil contamination, potential premium market value, and successful DWC trials—as well as challenges like delicate leaves, fungal susceptibility, bolting in heat, and the need for optimized nutrition and handling.
