PH PERFECT SENSI COCO GROW A Finally! A pH Perfect 2-Part Base Nutrient Designed Specifically For Coco Coir! pH Perfect® Sensi Coco Grow is a revolutionary two-part base nutrient that can be enjoyed by coco coir growers with absolutely any level of experience. This proprietary formula delivers humic acids, derived from natural leonardite, among other vital nutrients to your precious plants during the grow phase to ensure they grow to their full potential as quickly as possible. 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 coco coir growing media and 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.
