12 cfl's and no hps? I use cfl's just to add insult to the 50,000 lumens of hps beaming through the closet. Not sure what u mean about the setups, but most of the stuff I've seen on here can either be purchased at home depot, lowes, wal mart. Ebay's god good stuff too if u look
as for the fixtures.. you can make on yourself.. go to home depot and buy a vanity light (the lights that hang above bathroom mirrors in front of the sink.. they are a fixture with 3 or 4 sockets) then u just get some Y splitters . (these make a single socket into 2 sockets). . if you get a 3 socket vanity fixture, and 9 y splitters, it would accomodate all 12 bulbs... then all you have to do is make a DIY reflector and your in the game..
i would seriously consider getting the 23w cfls tho.. i say this because i know for a fact that 8 of them are sufficient to grow with.. i have been using a 4 bulb vanity fixture with 4 y splitters (thus making it 8 23w cfls) for over a year now. havent even changed the bulbs... i use it in my mother chamber .. they seem to like it..
your nuts man, i have like one or two 24 watt cfl's and mainly the 40 watt ones, dont waste your time with 15 watt, update that shit, get around 200 watts and your good
