First RDWC run. All 6 ILGM seeds sprouted in rapid rooters, kept the best 4. Top watering with RO water until the roots hit the waterline, then adding nutes to the water. 15 gallons seems about right for the whole system. The Artisun kit seems quality, though the air pump they sent was undersized and I replaced it with two additional pumps, each running 2 air stones. The pumps are outside the tent and I'm hoping water temp isn't going to be an issue. I drilled holes in the back of each bucket for the air line.
@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!
