Ph pen is in the post so I'm in the dark at the moment with actual readings etc. I was just curious about whether you was using tap water for your plants or something else. Reason being cant help much up to date info on London tap water ph levels ec levels etc. any help would be highly appreciated. Hoping I can just sit the tap water out for 24hrs and just ph it off after adding nutes. Peace
