So this is a citric acid ph down as opposed to a phosphoric acid one (like GH phdown for instance). The idea behind this is that citric acid won't kill beneficial microorganisms whereas phosphoric acid is harmful to living organics. Personally, I'm not sure how true any of this is. I've always used organic nutes and have used normal ph down without a problem. I decided to use this to be on the safe side.

Be wary, though, using this. This is not a fault of Earth Juice, but from using citric acid in general. You have to stabilize this stuff in solution for a while before use or the ph will drift. As an experiment, I would check pH as a function of time. This products tends to really lower your ph at first, and will slowly creep up until it stabilizes. I'd say it takes about an hour to stabilize and is completely necessary to have a consistent ph

Not good for hydroponic systems. Lots of build up and film, could not keep pH stable at all. Mine would start at 8.0 I would adjust it to 5.8 and within hours it would be over 9.0. Had to buy GH and haven't had a single problem since. This product may be better suited for soil. All my vegetables to a very hard hit trying this product.

Probably the best natural pH down product out there according to everyone I know myself included. It does the job well and it does so naturally.
