Ok, here's the deal. I plan on growing three plants in a small CFL cab. Right now I have eight 42 watt CFL's at the 2700k spectrum (20800 lumens total). I was planning on using these for my entire grow, but I have been reading that the red spectrum is no good for vegging, and that I should use the blue spectrum. My only problem is that the stores in my area don't carry 42 watt CFLs in the higher spectrums, so I would have to resort to lower wattage to get the blue spectrum. We're talking about 20 something watts putting out like 1700 lumens each. Would it be more benificial for vegging to go out and get 8 of the lower wattage blue lights, sacrificing more lumens for better spectrum, or keep the 42 watters and trade off spectrum for lumens? Maybe a mix of both?


Cliffs:

20800 lumens at 2700k or 13600 lumens at 6500k for vegging?
