How can I lower Ph, for a soil grow? - Indoor Grows - Soil - International Cannagraphic Magazine Forums

I have liquid ph down(gh), im not sure if it will lower the ph, which is at 7-7.5. What can I place in the soil to keep the ph at the right reading before i plant the mj plant into the soil? going to use 5 gallon buckets with soilless mix (no nutes to start with).

Run your water through a brita filter first, it drops the PH appropriately most of the time

I have used white vinegar before. It lowered my soil from about 7.5 to around 6.7.

I used it at a rate of 1tsp/gal. Worked like a charm for $1.37.

What about gen hyd ph up/down acid? I have used for 5 years and it works great.
You need little of ph down and much more ph up to get results. But it does work.

when phed water is poured into the pot of soil, does the soil become of that ph?

i use ascorbic acid (organic)... I've found it a little more for giving than phosphoric acid (inorganic)
