Thanks guys for the replies.

As for the heat issue, I will get an oscillating fan and keep the door open a bit, have a stand up fan in there blowing out and have a small space fan blowing in to simulate air flow and to disperse the CO2 inward, now if humidity becomes an issue which it might on some days, I will just mist it lightly in there to get the conditions right, eventually I do plan on using my bedroom as a grow room but for right now I am confined to the closet, also I will not be keeping the ballast in the closet, it will be outside as to not add anymore unwanted heat. As long as I keep the temps between 70-79 I should be alright, and humidity about 45%-50%?

I really appreciate you guys taking the time to help me here. I cannot get my hands on a 400W atm because money restrictions :/

I also ran out today and got 3 4in pots to start seedlings, 3 1 gal pots for later transplant, and 3 3 gal pots for final stage.
