Haven't seen a CFL grow for a while. That should be as good a mix as any.
I always liked running one 2700 for every 2 6400 for vegging smaller plants but would eventually get them under a 400W MH then a couple of 400W HPS for flowering.
How are you for drainage in those pails? I'd take a round file to the bottom rim or cut notches so water can get out from under easier and catch trays are nice too. I almost bought a bunch of those pails last time they were on sale for about $3 each. Sold without lids too at that price but you could buy them for another buck or so.
I'd check out those LED light strips to get some more light cheap for a better yield.
Plants seem to be liking it tho and look real healthy!
