how do u lower ph

how do u lower the ph level of water? i couldnt find it in the growfaq so i thought i would ask here.

You can buy "Ph up" & "Ph down". Use either a PH meter or a ph kit to measure your current Ph level. Then add either the up or down solution to the water, re-measure it again & repeat until you have the Ph level you want.

ya i have a ph meter but the ph is too high so ill probably buy the ph down, thanks alot

buy both up, and down.

vinegar if your desperate that will give you more acidic value; baking soda will give yo more alkaline value dilute first with good distiled water
