General Hydroponics pH UP (1 qt)
To maximize plant growth, the pH level of your nutrients should be slightly acidic. The ideal pH for most crops falls between 5.5 and 6.5. Typically, hydroponic systems will become slightly more basic over time, however, under some instances pH will drop and become far too acidic, causing nutrient lockout which is the perfect time to start supplementing with a basic solution to maintain optimal growing conditions.
General Hydroponics pH up is the premium solution for maintaining and raising pH levels. Base formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level for your crops.
