I grow in soil and my house water is well above 7. I collect rainwater for plant water which helps get the soil ph down in the high 6's
Vinegar works great also as a PH down! (Baking soda is a natural PH up also)
Rain water has EXTREME low alkalinity. Although this is what cannabis plants naturally drink, it Isn't optimal for them for vigor growth. Unless you have a great super soil. Dolomite lime in your medium really helps regulate your PH at the soil level. Therefore not needing to be so cautious about PH'in your water.
