HGV Condition - PH Up, 55 Gallon Powder Feeding by Green House Seed Co. It reads the room through17% Potassium Hydroxide pH Adjuster for Commercial Reservoirs Built around 17% potassium hydroxide and matched to the HGV Nutrients three part chemistry, this pH up shifts reservoir pH on a few mL per gallon.

The 55 gallon drum sizes it for central dosing systems, room scale fertigation skids, and cycled batch tanks where a hobby volume bottle would empty inside a week. Run it diluted.
