I need a quick solution for ph down in hydroponics other that ph down solution. Just in case I run out. Thanks in advance...
Well, if you want to replicate the contents of PH DOWN, add sulfuric acid to water. If you simply want an effect that is similar, dilute another acid with water. Lemon juice, vinegar, anything acidic will bring your PH down. *Household acids may be impure. My advice is to either go to the hyrdo/pet store tomorrow.
Thanks man for the info. I just went to the pet store and purchased a extra bottle. This stuff is gold for hydroponics!!!!!
