Description

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.

PH Down, second best thing other than the real thing - 85% Food Grade Phosphoric Acid

I got this gallon of PH Down because i'm living in a new spot that has terribly high ph source water. Id normally shell out the 200$ for a gallon of 85% food grade phosphoric acid as its the same thing without any buffer in it. Its extremely concentrated and that size of bottle would hold most growers off for two lifetimes, only ever needing a drop at a time. However. I needed something fast and didn't want to shell out 200$ for pH down. IndoorFarmer has been a blessing, with extremely fast delivery and is expertly packed and shipped out at warp speeds even during the height of the busy times during holiday sales. What else can I say. IndoorFarmer is one of a kind. Fair with pricing. Fair with shipping (this order was super heavy and they hooked it up free shipping. Thanks and heres to many more years of business.

Just Okay

The product works but I don't find it as potent as other forms of pH down (particularly compared to solid forms) and I have to use a lot to achieve what I'm looking for.

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!
