Thanks for the advice.
Ya I was thinking about T-5's. Supposedly they're slightly more efficient than the new CFLs.
The thing is they're $40 a tube @ my hydro store, and they are really skinny tubes, meant for seedlings.

I would need to find somewhere online to get a T-5 system. Also the minimum 24' length might now fit the best in my current setup, although I do enjoy setting it up differently sometimes.
I live in Canada so i'll have to see if I can find fairly priced T-5's somewhere. I don't like shipping over the boarder from the USA because you get slaughtered on shipping, and you lose perks like free shipping.
