Well, CFLs are the flourescents...

They consume X number of Watts... but they are 'comparable' to Y number of Watts. I'm guessing your 150W CFL is something like 45W or something...

Anyway, yes... CFLs will grow your seed. There are a couple of people here that grow using CFLs... I would suggest (plus a couple of other people) that you use a MH (metal halide) bulb for vegetative growth of your little plant... and then HPS when you place it into floweing.
