  • How much pH Down is needed per gallon?

    Created by Mark on July 5, 2018 at 6:52 pm

    Hi –

    Do you have a table or recommendations I can use to adjust pH in my hydroponics setup? Something like desired ph =’s X mg per gallon or ten gallons?

    Hi Mark –

    The ideal pH range for most hydroponic crops is between 5.5 and 6.5. However, we do not have a recommended table for adjusting pH. According to General Hydroponics you should start out with one milliliter pH Down per gallon. Wait 15 To 30 minutes, and test your water again. Frequently you will only need 1 to 2 ml per gallon of water. You may need additional pH Up/Down if you have hard water.

    Hope it helps!
