General Hydroponics PRO pH Down - Professional Non-Mineral pH Adjuster (Acid) - 6 Gallon - Pickup in Store Only
General Hydroponics PRO pH Down is a professional-strength, non-mineral pH adjuster that lowers the pH of irrigation water and nutrient solutions. It is nearly 3x as concentrated as GH's retail pH Down and, unlike phosphoric acid products, adds no phosphorus, nitrogen or sulfate to your reservoir. Supplied in a 6 gallon (22.7 L) commercial jug.
Key Features
- Does not contribute fertilizer, so it will not interfere with your nutrient balances
- Non-corrosive formula (label: HMIS 0-0-0, triple zero)
- Concentrated formula: nearly 3x the strength of GH's retail pH Down
- Alternative to harsh mineral acids with no added phosphorus, nitrogen or sulfate
- 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 decrease 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.
