HGV Condition - PH Up, 55 Gallon

17% 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 salt profile stays predictable across the feeding window. 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. Straight 17% KOH concentrate hitting calcium-rich solution undiluted is the fastest way to drop calcium phosphate flakes into your lines. Mixing Order and Dose Practice for HGV Condition pH Up Add the adjuster last, after silica, base nutrients, cal-mag, and any supplements have circulated and homogenized in the reservoir. Pre-dilute a working stock — a 1:10 cut of concentrate gives more controllable bumps. The diluted form won't spike pH in localized pockets when it meets calcium nitrate. Most growers find 0.25–0.5 mL of the diluted stock per gallon gets the solution into the 5.5–6.5 target range. pH response is non-linear, so start small and let the reservoir mix between additions. Key Features 17% Potassium Hydroxide: Strong enough KOH concentration to shift reservoir pH on small dose volumes, keeping drum-to-tank consumption predictable for commercial schedules. HGV Nutrient Compatibility: Formulated against HGV Condition, Growth, and Bloom chemistry so the K addition stays inside the line's intended ionic balance. 55-Gallon Drum Format: Sized for central dosing systems, multi-room fertigation, and large recirculating reservoirs where hobby pints don't last a feed cycle. Single-Active Formula: KOH is the only active — no phosphate or sulfate carryover that complicates EC tracking in tight feed programs. Dilution-Ready Workflow: Built to be diluted before use, so small mL increments give finer pH control than a drop of full-strength concentrate.
