Pure and concentrated Green Planet Nutrients pH UP/DOWN are used in your reservoir to maintain the optimum pH levels in your nutrient mixture. pH levels affect the availability and absorption of essential elements needed for plant growth. Plants growing outside of the optimal pH range will see slower growth and nutrient deficiencies. Maintaining stable and safe levels of pH will result in better growth.
Hydroponically grown plants will do best when the pH of the nutrient mixture is maintained between 5.8 and 6.3. When working with soilless mediums, keep pH between 6.0-6.5.
Add a few drops of pH Down to your nutrient solution to lower the pH levels. Test pH every few drops until the desired pH level is reached. The pH level should be checked daily. Do not mix with pH Up.
