Organic hydroponics is possible. Growers can implement organic practices for hydroponic systems by using nutrient solutions derived from organic plant and animal material or naturally mined compounds. In order to certify the organic origin for a product you must look for OMRI-listed products. The Organic Materials Review Institute (OMRI) is a private, nonprofit organization that determines whether or not a product qualifies as organic under the USDA’s National Organic Program.
Pre-Empt is an OMRI-listed product that can completely replace conventional hydroponic fertilizer programs. Pre-Empt was developed for recirculating hydroponic systems growing crops such as lettuce, leafy greens, basil, and other herbs. This fertilizer is created through five stages of fermentation processes that incorporate molasses with other natural plant extracts. This process packs Pre-Empt with essential macro- and micro-nutrients, amino acids like humic and fulvic acid, as well as an array of vitamins that build a full spectrum of nutrients.
Research by Hort Americas has shown that Pre-Empt does not need to have any pH adjusters added to the product in order for the plants to receive optimum nutrient absorption, although some wells may vary in alkalinity and may require adjustment. Citric acid is a commonly used product to lower the pH if needed. PreEmpt organic hydroponic nutrients can be used in conjunction with other products including other fertilizers, insecticides and fungicides. This product can be used in conjunction with a solution-grade organic gypsum (calcium sulfate) and magnesium sulfate.
