I'm not a pro by any stretch of the imagination, but I am a couple steps ahead of you as far as a first grow goes, so I'm encountering some of the same issues you will very soon.

One thing I noticed is you mentioned a 'lil fan'. If you look at just about any pic of a small grow-op, you almost always see that flexible duct pipe in the pic. As someone who is dealing with a heat issue now, I'll tell you that keeping the temperature down in grow area isn't as easy as one might imagine.

I have a 2' x 2' x 4'H grow box that I'm vegging some clones in. I have 411 (true) watts of cfls. With the door wide open, two fans blowing into the box and an ambient temperature of 75 F, the temps will barely stay below 80 F.

Once I get a couple of intake and exhaust fans, I should be able to more easily control the temp and keep it in the 70's. ... at least I hope anyway.

Be sure to save a some room in your budget for a good ventilation system. It is an absolute necessity.
