ok brief decription of setup.... oh btw light was raised just for picture purposes, anyway...
got a light fitting which holds 5 bulbs, right now theres 5 x 26 watt 6500k cfl's, & 4 x 225 bulb led's, mixed red & blue, (2700k bulbs ready for flower), ebb & flow tray for flower, but still using same tray have another line run from res & setup for drip system for veg, theres 10 gal res under shelf with airstones & pump, at top there a 135 cfm inline canfan with carbon scrubber venting through floor & intake low level, i made a monster light which was constructed from 4" solid duct, 3 pieces riveted together & it held 12 x cfl's, unfortunately this raised my temps to 105 so that light came out for now, post better pics soon.
