Yea doing a cfl grow can be very cheap , you just gotta know where to get suppply's at and you cant get much cheaper then walmart for cheap grows lol.You will need cheap extension cords (1.50each) and y-adapter's for lights (they let you plug to bulbs in 1 socket) (1.50 each) and a socket plug (basically it lets you plug a light bulb into a electrical outlet there $1) so with each exension cord/1 socket plug/2 y-adapters/ you can have 4 cfl bulb's. (and it dosent require any wiring! just plug and play , lol) all those things can be had near the lighting section in walmart.
