it would be fine for the 3-4 weeks, but in flowering your gunna want alot more lumens to fatten the bud up

I think i'll just buy 2 of these bulbs to produce more and stronger buds.

no, 1 of those a plant and a few 26w blue spectrums would though, but they wont be very big.

try getting some "daylight" cfls too i wanna say they burn at 5700k. i dont have a complete understainding of the kelvin scale and all but im sure that adding some of these with kinda broaden the spectrum and provide your plants with a wider range of light

stay high
