well...they're a good way through veg and looking really healthy like they're not far off from flowering, lots of new very healthy growths and the "nodes" i believe they're called where a branch grows from the stem and another branch and i keep a small fan in there all day not directly on them but right beside and also i use a big box fan everyday to recirculate the air but all i have at this moment is a 4' fixture with bulbs that i picked up at the local menards/home depot w/e it's called around ur area but thanx for the input wish i would have known some of that when i started but everything is looking good 'as of right now' and i'm currently working on another fixture with 2 more bulbs the only problem i ran into was the top leaves spread out towards the light and hog it all so i have some more tube bulbs on the wall trying to help out the fan leaves and lower brances, all in all it's not doing bad for a less than 50$ setup =\
