closet grow. plz help!

This is my first grow. I'm growing in a closet 24 1/2 '' deep, 67 inches wide, and 98 1/2 inches high. There is a shelf seperating the closet at 67 inches high. I'm thinking of making the shelf a divider for two seperate grow spaces. the top one a veg and bottom a flowering chamber. I'm planning on putting a 2 foot 2 lamp flourescent http://www.htgsupply.com/viewproduct...roductID=51907, for seedlings, and mabye mothers and clones in the future. I'm also thinking a 400 watt metal halide http://www.htgsupply.com/viewproduct...roductID=48449 for the top chamber. I'm also getting a seed starter kit http://www.htgsupply.com/viewproduct...roductID=48449. I plan on transplanting to 1/2 gallon grow bags and then to 3 gallon grow bags into a mix of vermiculite, pearlite, dolomite lime, and peat moss. On the bottom I already have a hps/mh 400 watt lamp, and was thinking about getting another hps lamp or mabye a light mover to make the most out of the space. It gets up to 90 degrees or so during the day and the only ventilation i have so far is a hole i cut above the shelf and stuck a window fan, probablly a stupid idea. If i make the closet into two seperate chambers i was thinking of gettin a 4inch intake fan rated for 170 cfm for the bottom chamber. will the window fan be enough for the top chamber? I will have ossilating fans in both. I bought a 3-pack of advanced nutes Any advice or help would be greatly appreciated.​

-flower up top with HPS, veg down low w/ flourescents. hid heat builds up and will radiate thru grow to exceed acceptable temperatures for sure(78-82f or up to 88 w/co2 enrichment). - Not a stupid idea at all with the window fan- yer barkin up the right tree there... get yerself an exhaust fan and forget the intake fan(the same fan could be either/or). duct your new exhaust fan to the hole you cut in the top of shelf and vent away hot air from the grow area, cut another hole in the bottom of the shelf and let your exhaust passively draw cool air from the floor into your grow shelf. cut vent in the middle shelf so that cool air can enter bottom chamber -pass thru veg area (cooling it), then passing thru bloom area (cooling it), and then blown out of the picture by exhaust fan. all this with 1 fan and a few holes, gettter dun'!

filters and all kinds of stuff you'll find out you need... but think like this= you dont want bugs, mildew, or poison on your medicine so at the very least put a screen on where the air goes in or chances are you'll wish you had
 
Wow thanks alot dude alot of good info there. My only worries is about light from the veg chamber entering the flower chamber. Any ideas?

Lots of things you can use. Panda film thats white on one side and black on the other to help keep light from leaking in or out. Black tape or weather stripping will work as well to help with light leaks. As far as if you are going to have any holes with fans between the 2 cambers you can build light traps. Youtube it and it will show you how to build one pretty easy and for cheap. GL

The two chamber idea is your only option unless you have another place to veg. You're definitely going to have to lower the shelf. Vegging plants and mothers require much less space (height). Cfl's should work for the veg chamber and generate alot less heat. Light traps are easy to make. A couple of ducting elbows and a little flexduct should do the trick. Paint the insides of the duct black to help dampen the light.
You'll need at least 2-400w to light that much flower space. The most efficient cooling and filtering is to use 2 fans. One for each circuit. HTG lights can come with a 8in.cooltube, very efficient air flow. A 4-500 CFM fan should remove most of the lamp heat. About 300 CFM on a carbon filter running 24hr. should remove any residual heat as well as the stank.
Two gallon bags should do the job as the plants aren't going to get big enough to need more. Saves so coin too.
George Cervantes has a book called 5 gardens, or something like that, has a chapter on a closet garden very similar to what you want to do. Check it out.
