i used 8 23 w 100w Equivelent 2700k Lumen CFL's and Two flourescent Tubes for front and back lighting but i would have to say it was better to one of the plants than the other so after this test run with the CFL's they are great!!! (and i had my doubt's going in but i was proven wrong the CFL's are capable of producing dense and sticky buds and quality smoke but i would for sure use 8 of the above mentioned CFL per plant bare minimum but to get what i got and to only have had to spend about 40 dollars i'd say thats pretty good huh? lol also just looked at your set-up and you did a much better job than me lol good job but my grow was just about as ghetto as it gets lol
