THANKS. There getting stonger now....put a bbq grill to add co2...oh, dont worry, theres a gas detector in the next room. Gas grill, only for about 15 mins every couple of days. There deeper green now. And stems are turning purple and stiffer. I think they where about 3 in, but I buried them a little and they are def going to make it now. new leaves darker green, stiffer stems. I put a bunch of CFL and a 2 tube 4 footer next to them (like almost touching them) and there inside a HPS dome. Like about 1 inch away, but its ONLY 70 watts so dont have to worry. very cool. I think its going to work.
