What would you guys do??? (noob)

Alright gentleman. Yet another noob going coming at you with a lot of the same questions. I've been doing my research, but in this specific instance I'd like to know how you'd personally handle it. I got a closet for a cfl grow I'm using that's 27" deep x 32" wide x 66" tall. I'm going to put a 1/2" shelf in the middle of the closet so I can do one plant on top and one on bottom at separate times and I was thinking about doing LST due to the lack of height. The inside of the closet is already painted flat white and I've decided to do soil for my first grow, I'm getting some clones. Now, with that being said, I want to know what you guys would do yourselves when it comes to these particular circumstances. I've read about mixing different spectrums with the cfl's during either the vegging or flowering stage but can't remember the formula for how many kelvins / lumens per sq ft. I also forget the formula for how many cfu's I'd need in a fan for the volume of the area. Would a computer fan work? I was also wondering how do I hook up a fan outake / intake without letting light get into the closet? Can I put some cfl's underneath the plant to help the lower branches or would that not be necessary if I do the LST. I'll get into the nutes and more later cause right now I'm just doing the set up. If you guys would be so kind as to tell me what you would do, I'd really appreciate it!

I grew two very healthy plants with 6500k cfl's. That's what you veg with the ones I bought were made by GE and can be found at any walmart. I would use as many as you can fit in for max lumens. When they flower you will switch all bulbs to 2700k for red spectrum flower. I would not mix bulbs. I used 3 cpu fans to keep temps under 80f , they worked well. You can use dryer duct for the intake/ outtake but you have to have allot of bends to keep it light tight. I had my box in a closet in a blacked out room so it had 3 fail safes, the box, the closet door, the windows blacked out and the bedroom door. If I was growing in just a closet I would buy a powerful tower fan instead of cpu fans. If you can't cut holes in your wall or your closet door , you should make a faux wall. Like just a big piece of wood or hang up blankets over your closet door and vent under the blankets. it's gonna look sloppy but fuck it.
