pH Up 1 Gal

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. Base is formulated using Potassium Hydroxide and Potassium Carbonate - pure plant nutrient. Add a little at a time if your nutrient pH is too low and this will raise the pH to within range.
