i have two plants in a small growroom i got two CFLS and one 75watt fluro tube vertically, one cfl is 68watt but is a 300watt equavilent, 2700k and 4200 lumens other is a 40watt but 150watt equavilent is that good enuff?
They will work just fine, they are in the spectrum for veggin a crop, when it comes time for budding you need a lower spectrum cfl 2700 K.
Just get some more cfl's that are more yellow, called warm daylight 'round 'ere. Your current lights are 6700k, get a couple more (that add up to atleast 100 actual watts) that are 2700k for flowering; just take the 6700's out and put-in the 2700's and switch to 12/12. Easy.
