I am about to start a new grow but this time is going to be indoor. I have read that for the VEG stage the CFL lights should have 6500K and during FLOWERING the lights should have 2700K. My question is I have some 11 watt CFL's in my house and they have 2700K, Can I use them? or are the watts to low? Since the watts are so low i was planning on having 4-6 lights. How much do the watts matter? Help greatly appreciated.
