pH Down 30%
For plants to be able to grow best it is important that the nutrient pH be slightly acidic - the range of 5.5 to 6.5 is considered ideal for most crops. Even when using quality hydroponic nutrients, the pH may fall out of range when poor quality water is used to mix nutrient solution, when pH unstable media is used such as many rockwool and gravel products and when plant growth rates are so high that the nutrient mix is thrown off due to rapid nutrient absorption by the crop.
Sizes Available: Quart, Gallon, 2.5 Gallon, 6 Gallon
