Managing a non-recirculation hydroponic unit for commercial lettuce production


Hydroponics is the most common method of soil-less culture (growing agricultural plants without the use of soil), which includes growing plants either on a substrate or in an aqueous medium with bare roots. Non-circulating hydroponic methods, importantly, do not require electricity or a pump. With the method presented in this document, the entire crop can be grown with only an initial application of water and nutrients. No additional water or fertilizer are needed. The crop is normally terminated when most of the nutrient solution is consumed. This document provides a detailed description of how to fill and manage the non-circulating hydroponic unit for commercial lettuce production including the application of fertilizers, the seeding, transplanting, growing and harvesting.
