PH PERFECT® SENSI COCO GROW B Finally! A pH Perfect 2·Part Base Nutrient Designed Specifically For Coco Coir! pH Perfect® Sensi Coco Grow is a two-part base nutrient designed specifically for coco coir growers to help aid in the delivery of essential nutrients to your plants during the most vital period of their grow phase to ensure they reach their full potential in both size and quality without pushing back your harvest. If you follow the label directions, pH Perfect® Sensi Coco Grow Part B 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 B is an invaluable asset to your growroom.
