Ok so iv worked out i want to veg with red and flower with blue.
How do i find out what cfl/fluros give out what spectrum, is it possibly 6200-6400k (kelvin) is blue and 2400-2800k is red or is it that cool and warm bulbs are blue and daylight are more to the red end.

Can someone please correct me as in Australia fluro/cfl lights either have kelvin or cool/warm/day never both so im a little confused. If someone could just tell me what sort of bulbs i need for flower/veg and how to distinguish between red and blue that would be great.

Thankyou in advanced
