If an HPS is out of the question, then BY ALL MEANS, throw some warm spectrum CFLs in there.

BY ALL MEANS.

She is light deficient to a degree although you have done a nice job with those shitty lights.

Throw in all you can for red spectrum...try and find 2700K ideally. They sell those 125W 2700K big bulbs like I use for about $100.00

But yes you can get a bunch of the warms and lower the Kelvin which will mimmick late summer light angles, or red shifting.

I would add a couple of the regular CFLs you are using now to the sides / bottoms though.

This is where it will get tricky, as you need to have them close, but the tips and small budlets will burn if the touch the lights.

Good LUCK MB
