you can get those Y adapters at home depot for under 3 bucks a pop and I just hang an extenstion cord down the middle of the grow box with multiple female sockets at the end and start with just a male plug-in that fits a bulb and stick a Y adapter in that then another 2 Y adapters in that one so essentially you can fit 4 bulbs and I do the same on the other side of the extension cord so I have 4 cfl's hanging on one side and 4 hanging on the other for a total of 8. then I hang 2 cfls on their own on each side of the extension cord where theres a gap between cfl's. 10 cfl's at 23-26w each. this is enough for a few flowers, especially if your growing in a 2.5 sq. foot box like me. add mylar or some other reflective material around the lighting area. I use miracle grow and seems to work fine. just be easy on nutes and water and you'll be fine. good luck:thumbsup:
