T5 users: is 6500K needed?
I am running one sunlight bulb out of 6 of them color temp 6500K.
It would be a good bulb for a room like reading a book but seem to cast a yellow tint on the whole tank and I think this bulb is the cultprit?
The question is does the SPS need this to grow well, or should I swap it with something more white and blue, some numbers I got says the sunlight bulb is around 340 PAR and ATI blue plus is like 310 or so. Or maybe swap this out for a red bulb ATI pro color but much weaker PAR.
