what is recommended for flowering?
so far, i've only used 2700k cfl's
that seems to work very nice, though i did get carried away with using the same set of cfl's for 2 years
they had begun to run out of gas, hard to tell from the eye but yields began to suffer
i'm not really up on the t5's if that's what you're planning on flowering with
there may be some quirks with t5's for flower, they look to be very good for veg
