right now i have two 25w compact fluorescent lights, and a 15w 18" tube. im about to harvest, yes, harvest, it looks to me like ill only get about 1/2 to 3/4 of an Ounce off of a like, 4.5' plant. I let it grow too long before flower because i didnt have a timer. but anyway, im gonna buy some more fluorescent tubes, $10 each isnt a bad deal, my grow space is about 20"x 20" x 60", i was thinking about getting probly 5 more 18" tubes and two 4 footers for the corners (upright). id get an HPS, but it would be a fire hazard, and its easier for me to run fluoros (it just IS). what do you guys think? would ~250w fluoros be enough for my space?
