I've been buying T5 High Output, 4 ft, 4 lamp fixtures with two grow tubes (blue) and two bloom tubes (red). They used to cost about $140 each but the price keeps dropping. I think I paid $86 (delivered) the last time. I like dealing with Growershouse.com.
Recently someone told me that the flouresent tubes lose a lot of spectrum very quickly. Don't know, I get spectacular results with the phals. Not so happy with the results on the cats and dends.
Planning on going with the 4 ft leds. That will cost closer to $200, and consists of
