This concentrated General Hydroponics pH Down solution is basic equipment for any hydroponics system. pH levels will vary greatly depending on your water source and the makeup of your nutrient solution. When pH drifts, nutrients are used differently. Improper conditions can even prevent roots from taking up nutrients at all—essentially starving your plants! Most plants require pH levels between 5.5 and 6.8. Add pH Down to your nutrient solution to lower pH levels.
