Are two 25 watt CFL's efficient enough life for only one plant in my closet? The one plant im movin indoors is only around 18 inches, i got it started late in the season so im gonna put it indoors. It can grow up to 6-7 nft. before it has to be cut, and has about 2 ft. across to grow. will these lights be sufficient enough for the whol process or will i need something a bit stronger for flowering?
