General Hydroponics PRO pH Up
PRO pH Up is a professional-grade pH adjuster built specifically for commercial facilities, using a non-mineral formulation so it does not add unwanted nutrients such as potassium hydroxide to a carefully constructed recipe. It carries nearly three times the concentration of the retail adjuster, so less volume is needed per correction. The formula is non-caustic and non-corrosive with a zero rating across all HMIS categories, and it is not HAZMAT listed like many competitive products, which reduces shipping costs. It is intended for operators managing nutrient solution and irrigation water at scale.
PRO pH Up is dosed in small amounts into the solution being corrected, mixed well, and then re-read once the value stabilizes, repeating until the target is reached. Most crops are managed to a pH of roughly 5.5 to 6.5 depending on crop type and growth stage, and recirculating systems should be monitored daily. Because it contributes no fertilizer, it can be used without disturbing nutrient ratios in the tank. It suits vegetables, herbs, fruits, blooms, plant material and other high-value crops grown indoors or outdoors in rockwool, coco or potting mix.
