Clearly Superior Blends. Noticeably Better Results. Cultured Solutions liquid fertilizers were developed for precision irrigation applications such as Aeroponics, RDWC, and pressure-compensated drip. These productive methods all require an exceptionally clean nutrient formulation to operate properly. CS is blended at high temperature using pure RO water, refined mineral salts and followed by an extensive Triple Filtration Process to remove any residual impurities. This carefully executed series of events produces the world’s cleanest, most effective fertilizers for CEA & Greenhouse crop production.
