the cfl i use are from the home depot...if you go through electical they sell these 150w max clamp lights for about 5 or 6 bucks and splitters for about a buck. So now your clamp light can hold 2 bulbs. for my veg i have
4-27w blue spectrum bulds and 2-42w red spectrum for flowering ill switch probable all but one to the 42watters. im using a dwc bucket that is on top of a wire rack i got at wallmart for 15$ the lights clamp on perfectly to these adjustable racks. and since you can move these clamp lights you can get them very close to the plant and raise them whenever. my plant is also in a growbox i got at homedepot, one of those little workforce garage storage things. i put two computer fans in one echaust the other to cool the plant and my cfl still heat up the box a little so i cant imagine what a hps would do to that small of a space.. if i go with hps later ill deffinately get another fan.....remember the worst thing that can happen is you start a fire....if this happens youll get busted and not have a place to live.
