Im my current micro grow i use two 24W T4 fluoro fixtures for side lighting:

ATM the bulbs are 6400K but i also have the 4000K ones that came with the fixtures.

I am reluctant to swap out the blue ones for these "daylight" ones as i know the CRI part of the spectrum is wrong for plants.

Since im in flower and these run of the mill fluoros probably have very low CRI, would it be better to swap out blue (which the plant may not need so much of in flower) for the ~30% red i would probably get from the 4000K bulbs?
 
Rats - every damn grow seems to be an experiment :P

I think im going to change them based on the non CRI light being redder.
