Often times on this last grow when I didn't have Poland springs on hand I would just use my tap water which has one of those PUR water filters you hook right to the faucet. They claim it removes 97% of contaminants, sediments and chlorine. So I gave it a try only thing is The ph of the filtered tap water would always be around 8.8-9 and that's a little high for my liking. I would use earth juice crystals from there to bring it to 6.5ph. Now I'm not to sure if that much of a gap could fuck with the soils ph over time and cause other issues. Anyone know anything about that? It didn't seem to cause any issues this last run but I wouldn't really know it was my second grow lol.
So next grow I'm gonna just stick to using just the store bought spring water that has a steady 7.8ph off the gate and bring that to the desired 6.5. Plus Im pretty sure innoculants like mammoth p won't work as well unless the ph stays at a steady neutral. Any thoughts or comments would be much appreciated guys. That airpot I used made her a really thirsty bitch, once she was established she was burning through 1.5 gallons a day which is 10.5 gallons a week. No thanks I'll go back to smart pots which usually it's every 2 or 3 days a watering depending on growth stage.
Yes, that far off will screw up your soil's pH over the long run. I ran a test with it on one of my males on the previous grow and it started showing up in the plant. I changed back to pH'd water to the 6.5-7.0 range and the plant looked healthy within a few days. Now my water is even worse than yours at 9.2 or 9.3. I think if you had tap water around 7.5 or lower you would probably be ok.
