It's good to hear you had to try different stuff Z. I was beginning to think you were born with the knowledge.
I have friends who come over and check them for me. I can set them up for about 10-12 day's with out touching them. But that depends on the cycle they are in. Early in veg and after the first week of flower I'm good to leave them for about 10-14 day's. Those are the slower periods where Ph is the most important and the nutrients are not as strong so you don't need to watch them as closely as other times in the cycle.

My knowledge comes from many years of failure. With out failure you will not have true knowledge. "One must fall and get back up many times before he can learn to run faster." I also have a very extensive book collection, as well as the ability to learn from reading, then pushing and challenging what they said and seeing for my self. I had an opportunity in the early to mid 70â??s to spend summers in Humboldt with friends. I spent several weeks helping them plant, care fore and then harvest many, many times.

That was a very long time ago.
Zandor Reviewed by Zandor on . using CO2 to control ph I just found out this incredible thing today. Using CO2 to control ph. Mountainman talked about getting a controller to build a ph adjusting machine. Someone posting about using CO2 to control ph. Armed with my new soda club machine ($79 Edition 1) I was ready for the challenge. Today I measured tap water with CO2 and without CO2. The same with R/O water. Seltzer water is plain water injected with CO2. Here are my results. Tap water with CO2 5.4, 5.0, 5.0 5.1 Tap water Rating: 5
