I have a few cfl bulbs at home however I do not know which ones are daylight bulbs and which are cool white bulbs. Can anyone tell me which one is the yellow looking one and if thats the one for veg?? I'm assuming the yellow light is the daylight and the white is the soft white?

the redish ones are roughly 2700k color temp (flower), the blues are in the 6500k (vegg) range. dont worry about switching them around for vegg n flower, toss em all in there. keep a multitude of spectrums going. your plants will thank you.

For better spectrum coverage... I would use both bulbs in vegging, alternate them instead of together or use 3 daylight and 1 yellow/orange. It is actually proven fact plants use many spectrums during vegging & flowering. When its time to change to flowering just reverse, 3 yellow/orange and 1 daylight.

What about a 4100k? Can I throw that in there as well?
Thanks for the help.

this is what i do in a pc case with 4 26w bulbs, 3 6500k, 1 2700k for vegg, switch for flower.


and yes, 4100k is fine. the only light that you wouldnt need to put in there is like a green party bulb.
