I couldn't keep the water temps below 81 comfortably so I'm not going to bother with the RDWC right now - I bought more autopots and transplanted the rooters to solo cups in coco + perlite. I'll break the RDWC back out when it's cooler.
@BigDaddyK, It's all good - I'm hanging it up with this RDWC, though. I'm growing in a garage in the desert and to keep the water temp low I'll have blast the A/C. I'm buying more autopots and packing this system up until December!
