I'm a little confused as to what you are using.I've got several one inch sprouts under a 40 watt CFL bulb. It's a nice bulb, but it's under the 2700K spectrum of light and apparently I did 6500k for vegging. Will the one I have now work?
Also say I have 3 plants, should I buy a 250 watt hps or a bunch of CFL's?
