yes he had excellent results . i had a link to the grow diary but unfortunately the canadian police have that server now! i wish i could remember his name. i was interested in t5's instead of the t12's i now have. t5's put out alot more light than ordinary flouros without a great deal more heat. it is still a great idea if you have the right space. i love my 4fter's i get a great footprint from 8 of them. 2ftx4ft exactly with all plants getting equal amount of light. that's why i haven't switched to a 400mh.
