yep, i am just using CFL's, i decided to put most my money into good ferts and nutes rather than expensive lighting, i do have a LOT of bulbs in each tub though, 10 per tub. Im running 6 100w general puprose CFL's and 4 60w soft blue CFL's (26w and 15w actual). Im thinking about getting an HPS for my next grow since this one is going so well but if i get decent yields why fix something thats not broken?
