I start with the water right at netpot bottom, but I also have enough bubbles to wet the hydroton even if water level is lower.

maybe airpump is weak???
latewood Reviewed by latewood on . n00b Bubbler Question Ok, I know this is as dumb a question as they get: When I suspend the Rapid Rooters in the netpots with hydroton, how much water goes into the bubbler? I had it up to just 1/4" below the RR but they keep drying out...should they actually be sitting in the water? I guess I was thinking the bubbles would moisturize the RR but it doesn't seem to be happening. I added more water and now the RR are damp all the time. Is this right?? Rating: 5
