General Hydroponics pH Down Professional

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!

Perfect for adjusting ph

Good buffer

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.
