General Hydroponics PRO pH Up - Professional Non-Mineral pH Adjuster (Base) - 2.5 Gallon and 6 Gallon - Pickup in Store Only
General Hydroponics PRO pH Up is a professional-strength, non-mineral pH adjuster used to raise the pH of irrigation water and nutrient solutions. It is roughly 3x as concentrated as GH's retail pH Up and, unlike potassium hydroxide adjusters, it does not add potassium or any other fertilizer nutrient to the reservoir. Sold in commercial 2.5 and 6 gallon jugs.
Key Features
- Does not contribute fertilizer, so it will not interfere with your nutrient balances
- Non-corrosive, non-caustic formula (label: HMIS 0-0-0, triple zero)
- Concentrated formula: nearly 3x the strength of GH's retail pH Up
- Alternative to harsh mineral hydroxides (potassium hydroxide) with no extra potassium added
- Not HAZMAT listed, per the manufacturer
- Works in rockwool, coco, peat/lite mixes, in-ground soil and water culture, indoors or out
How to Use
Directions on label: the volume needed to achieve your desired pH will vary depending on your source water and the products you use in it to make up your solution. Apply very small amounts to the solution you wish to increase the pH of and mix well to allow the pH reading to stabilize before adding more. Repeat until your target value is reached. For recirculating systems, check the pH daily. Recommended pH for most plants is 5.5-6.5. Keep out of reach of children; store in a cool, dark place.
