sorry hanayama, still no pics but an update
all 8 look to be doing pretty good, starting their second set of leaves on the other four. They are about a finger length from leave tip to tip, and anywhere from 1" ~3" tall.
two have root systems extending out of the cups.
I gave them some nutes today. 2tsp of GH FloraMicro and 2tsp of FloraBloom. I mixed it into a gallon of ph'ed water and then poured into the rez, which had ~6 gal already in it. So thats about 1/7 the strength GH has to provide clones. I don't think it'll cause any burn. I figure to move up to 2.5tsp/gal sometime next week. I figure to keep that as the baseline and adjust from there as I don't have a ppm kit.
One of my buddies dropped off a plant, it looks pretty sickly, ~7" tall and 3leaves on it. He went to burning man and didn't take care of it. In addition to using regular tap, which around here has a ph of 7.5-8. So I flushed that with a gallon of ph water ~6 and the runnoff at the end was ~6 so hopefully it'll come back to us.
Temps are staying between 75-83 which isn't too bad. I need to get some reflective stuff for the tub top, as the lid heats up to ~90
Water temps are staying cool. I place a frozen 2L bottle in the rez every morning. I think once I collect some more I'll go with 2-2L.
Hopefully we will get a good selection of females out of these 8. I'm figuring on 4 but am prepared to deal with getting 2 or 6....

I'm pleased with how covert our setup is also. Several people have walked into the room and none could tell a thing. The fact that the larger room is being used for storage provides an excellent place to grow, highly recommend it.
Try to get pics up, im gona see if i can find some AA's for my camera
