All 6 plants have started putting out new, healthy growth at the top, and they're showing some root growth in the reservoir too. Looks like they survived the abuse and transplanting
I lowered the lights about 18 inches this morning and increased the TDS to ~700ppm. pH was at 6.0 when I checked, and the nutes will lower it just a touch. Temps are already a problem so I changed the lighting to 18/6 to give the hut a bit of a cooling off period. I'll have to hook up the water chiller this weekend, since it looks like I'll need it.
