I use drip and bubblers. Leaning more to the bubblers now. When you do a rez change it seems you might chase it down for a couple of days and then it mostly levels out for the rest of 2 weeks. If I start to have bad ups or downs I look for a problem. We were just fighting root rot and the PH was all over the place and you could not hold it.

Had to leave and came back to read some interesting stuff CFL. Thanks.

I use R/O maybe more stable.
