Electrifying! Since 1991 the #1 additive for hydroponics and soil gardeners world wide. A natural, organic, molasses-kelp based liquid nutrient that aids plant growth and production. To be used as part of a complete fertilization program through all stages of plant development. Also functions as an excellent “finishing” formula for determinate plants. May be used solely or in conjunction with all soil and hydroponic fertilizers. Highly recommended. For indoor/outdoor plants, soil and hydroponics.
