Yes, I've got a bottle of distilled water PH'd to around 6.2 with a small airstone in it for oxygen. I'll go snap a pic of that real quick.Are you PHing your water bro? If not, I suggest you start doing that. You can get a kit from Wal-Mart of Home Depot for like 5 bucks or something. A bottle of PH down will cost about 5 bucks at the pet store.6.2-6.5 should be ok for soil.
