I think rain water ph level is 7. I need to lower it to around 6.5. How much vinegar to how much water? Need to know ASAP please. Thank you

Make sure you are using distilled white vinegar, not apple cider or anything else.
I use 1 cap full from the Heinz bottle, per liter of water, and it brings me down about one full point.

Rain water pH will surprise you....it's typically near 6.0 or lower.

Don't guess w/ pH...get yourself a quality meter and calibrate it regularly.

Good catch........
I didn't even think to mention that, just assumed OP had already checked it, and knowing my rain water is 6.6, well..........

buy a ph meter then add vinegar until ur at the correct ph.
if you don't have a ph meter you're doing it wrong

General Hydroponics has a PH kit that is economical,and works.
Knowing the PH is very important.

Buy a nice ph meter. Get pissed at it when it fucks up. Throw it away and buy a $7 drip test kit from the hydro store.
If you are not color blind it works fine.
