i test with a milwaukee digital ph tester. If the water was ph 7 i probably wouldn't use ph down until the domolite lime ran out in the soil unless i could see an issue. If you have been doing it that way without problems then the last thing you want to do is listen to me. I suck at growing lol.
michaelpeg Reviewed by michaelpeg on . distilled water ph I just bought some distilled water expecting the ph to be around 7 and it turned out to be ph 8.2 why is this? i searched google and the sites say that the ph should go down from 7 because co2 is added when you open the bottle. Rating: 5
