Directions:

Fill your reservoir with clean water before administering any nutrient or additive. Make sure that the water level in your reservoir is sufficient enough to effectively flood your desired area or table. Potential nutrient lock-out can be avoided by adding Master A to your reservoir first and thoroughly mixing it in, then add Master B. Never mix these nutrients together in their concentrated forms. After adding in each nutrient adjust the pH of your reservoir between 5.5 and 6.5. Keep the water temperature in your reservoir between 65 and 75 °F. Drain and clean your reservoir and pumps at least once a week to prevent any salt buildup. Avoid storing in direct sunlight and protect from freezing.
