Advanced Nutrients pH Up 0-0-38 | 57 L Hydroponic pH Adjuster

Advanced Nutrients pH Up 0-0-38 for Reservoir pH Control

When reservoir pH slides below the uptake range, roots stop pulling the feed a grower already paid for. Advanced Nutrients pH Up 0-0-38 pulls that number back up before a lockout sets in, using a potassium hydroxide concentrate. The potassium base lifts pH without adding nitrogen or phosphate that would skew the mix. It works the same in soilless, hydro, and soil systems, so one drum covers every bench. This is the 57 L commercial size, meant for rooms that correct pH day in and day out.

Dosing a Hydroponic pH Up Adjuster into the Reservoir

Growers add it in small steps, around 1 mL per gallon, then stir and recheck with a pH meter within the hour. Target roughly 5.5 to 5.8 in soilless and hydro, or 6.2 to 6.5 in soil, where plants feed best. Because the concentrate is caustic, wear gloves and add it to water, never water to it. Dialing pH a few milliliters at a time keeps a big reservoir from overshooting past the window. For a commercial room, the 57 L drum turns a daily correction into a quick, repeatable step.

Key Features

• 0-0-38 potassium base: Raises pH without adding nitrogen or phosphate.
• Potassium hydroxide concentrate: A strong, pharmaceutical-grade pH raiser.
• Works across systems: Soilless, hydro, and soil reservoirs.
• Small-dose control: About 1 mL per gallon nudges pH into the uptake window.
• 57 L commercial size: Enough to correct large reservoirs over a full cycle.
