It's raising the ph of my water in my hydro system uncontrollably. This is the same issue I had with it before and was the original reason I switched to higromite rocks. At the time I used it before however, I was not using RO water which I thought would make a difference when I switched back but it hasn't.....at all.

I rinsed the rocks and let them soak thoroughly before use.....there was very little dust on them afterwards. I ran the system for two days to disinfect it and have had seedlings in it for a week. The ph is rising several points a day and it's getting to be a really huge problem. There are no nutes in the system....strictly ph'd water....and if I'm having to adjust ph 4 times a day to keep the plants stable....if I miss one they start wilting immediately. I've changed the rez on the plants three times but nothing I've done has made any difference.

I was trying to "wait' out the newness of the rocks but see no changes at all. Unless it stablizes I guess I'll have to toss these and start over with some higromite....I have no intention of standing by these seedlings with ph down for a few months hoping to squeeze them through and having to play defense.

I haven't heard of anyone else having this issue with hydroton but I'm certain it is the problem since it is absolutely the only thing that is different in my setup from before and it's exactly the same problem I had before when using it. Anyone else?
