What is the best PH Down brand?

[MrMonkey420]

citric acid

[treetrunks]

I use 85% phosphoric acid whatever brands cheapest usually the hydro shops will have their own bottles

[Mark0427]

If ur doing hydro style any kind of pH pro will do good usually the professional kinds hold pH alot better with less fluctuations. Or u can do acids like the boys say. I myself been using bloom city’s pH pro and it seems to work super well for holding pH good
