The spiral CFLs you use in house fixtures? If so, no, that would be perfect for a low tech tank. Just make sure the spectrum is between 5000K and 6500K for best results. I use shop lights with those types of bulbs as well.

I'd stick with 10-13w lights unless you are very heavily planted. I used 3x13w CFLs in 10.25" shop lights over my 75g until my vals completely took over. I then upgraded to 23w CFLs. But if you have less plants than this:
I'd stick with 13w for now. You'll just end up with algae if you put too much light on a tank without enough plant mass. Side note, if they are vertical vs. horizontally mounted makes a HUGE difference in the light output of CFLs.

p.s. i want my plants to grow lightning fast, if that makes any difference. I don' know about you guys, but I like fast growth, the faster the better.

Freemanana, (not get off topic, but)this is a beautiful tank, don't know if I had mentioned it before. Is that right 75G? Do you use CO2 and if so, are you just diffusing it into the tank from one location?I'd stick with 10-13w lights unless you are very heavily planted.
