If you follow the label directions, pH Perfect® Sensi Coco Grow Part A will keep the pH of your nutrient solution stable within a range optimal for nutrient uptake for one week. For optimal results, we recommend using reverse osmosis (RO) water or water up to approximately 100 ppm (EC 160 μS/cm). This product is specially designed for use with diverse hydroponic growing media, including peat, rockwool, and expanded clay pellets, and all continuous liquid-feed growing systems such as aeroponics, drip irrigation and emitters, NFT, flood and drain, and deep water culture. And since it also contains our proprietary pH Perfect® Technology, eliminating the need for pH and ppm metering, pH Perfect Sensi Coco Grow Part A is an invaluable asset to your growroom.
