1st grow - feedback/advice greatly appreciated

First time grower and I need to keep things as cheap as I can.

I'm starting a small grow (2 buddha white dwarf autoflower feminized plants) in an outdoor closet with white walls that is about 4 x 2.5 x 5.

My grow starts next week so I am still setting up my grow room now.

Here are my plans and issues, as much feedback as possible:

Since they are autoflower, I'm going to keep the cycle at 18/6 and I'm going to use CFLs. With just two plants, what type and how many CFLs would be best?

The closet is plenty big but does not have ventilation. I'm going to have a fan and a small air purifier and open the door once or twice a day. I don't think smell will be a huge issue but obviously I want to be safe as I have some close neighbors and it's an outdoor closet.

I know nothing about nutes. Any suggestions here?

I'll post pictures when I get things ready. Thanks for any advice/tips you can provide!

Your going to need better venting than opening a door a few times a day. How insulated is your closet? check out http://www.planetnatural.com/site/cf-bulbs.html for the type of CFL's I'd use if I had to.

The closet is very insulated. One side shares a wall with my place, the other has a brick outside. Door is solid and I'm renting so I can't do any permanent work on it.

I had hoped that by putting one or two small air purifiers and only growing 1 or 2 dwarves in my decent sized closet would be enough venting. If that won't work, any advice on venting?

If I'm not able to do anything besides using air purifiers, fans and opening the door, will it keep my plants from growing or would it just stunt them a little?

They'll grow just fine(a little lower yield probly) you just have to watch out for mold in that situation because of high humidity, invest in a small Eva-Dry dessicant closet dehumidifier and have good fan circulation and actually go in there a lot.

carbon filter sure wouldnt hurt either
