To maximize plant growth, the pH content of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However, some important exceptions do exist. Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or pH unstable media - such as rock wool and gravel products - are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.
pH Down: Acid formulated using food grade Phosphoric acid. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level.
Perfect for adjusting ph
Arrived in a timely manner, I’ve used it with my general hydroponic nutrients and definitely used less of it as well, as more compatible than another brand I had been using. Happy!
It's ph down
The best price and best to use in my opinion
1QT General hydroponics ph down arrived safely and fast. Love how just couple drops does what most other brands needs a few ML to achieve. Thanks Indoor farmer.
