I've been vegging in a 60*60cm cab for a long time - and it's really a bitch to supply enough clones for a 600W cab like that. I decided to do something about it and went for 36W 6500K flourescents, as those are pretty effective (3250 lumens). Then I just built a cab from wood and panda and hung the lights. The plants are already loving their new home - can you believe that all of these plants were in half the area 1 day earlier? I've got a lot of repotting to do still - the ones you can see to the left are freshly repotted to 13cm pots. 2 days after repotting those they had already grown a lot, and roots were starting to poke out of the bottom holes in one pot. As you can see from the yellow leaves here and there it was in due time I finally got this done. Yesterday I potted some rooted clones that had been sitting in their peat pellets for tooo long - they were actually starting to veg in them and I just know they'll take off like crazy now
