Hey everybody, I'm looking for some advise on a DIY T5HO lighting set up. I have the set up, fixtures and a Plan. What I'm looking for is the bulbs. I've had several friends tell me just to get a full spectrum 6500K bulb and not to worry about the pinkish rosette plant grow bulb.. that the full spectrum 65K is like sun light and I wont need the rosette. Does anyone know if this is true and if so what is the rosette even for?
