1 week under 600 watt mh then I changed it to hps and she took off....im not saying i didn't mess up the stats with the mh but comparing the 2 I will go hps straight threw on the next run. I was going to clone her and make 9 and take them straight to flower for one cola each but then I realized i don't have the room for a flood table...now i have 8 off shoots and the main which should yield about the same if not more in less time...
