Building a half-closet grow

[Calimed]

I am planning on utilizing half of my sliding door closet (3-4feet wide, 20inches deep, and 70 inches tall) and a 400w hps for about 2-4 plants running DWC.

I am thinking of just buying a bunch of panda film, lining the walls, ghetto wrapping it around the back of the sliding doors, and then making a velcro strap somewhere for access.

The main concern, is how much fan power and what type of filter I would need. I think a 4inch fan with a can33 or the 4inch fan/filter combo at htg.

Does anyone have any suggestions?

There's a link that might help you decide on which fan/filter you want.

My demensions aren't much smaller than yours 30"x20"x72", and I went with a 193cfm fan with the Can 33.

My room is a little larger (2x6 and 7 feet tall) and I bought a 6" Soler & Palau fan TD-150 that does aprox 200cfm on low speed and 285cfm on high. I probably could have gotten away with using a 4" fan but my hood had hookups for 6" ducting so for the sake of ease I went with a 6" fan and 6" charcoal filter...I also use a speed controller and so far this combination has been working great! The fan cost about $140 including the shipping....

I checked out the fan calculator the above poster listed and it looks like I will need around 256cfm. I saw a can fan and can33 filter on htg that can fulfil these requirements. Does anyone have experience with this combo?

My other question, should I stick to 3 plants under my 400w hps, or can this light handle 4?

One other question, As I have been researching what clones I can get through the clubs, would mixing a couple purple plants with a couple sativas like trainwreck in the same cab cause any problems? I heard sativas like to stretch more than indica, but maybe I can just train them well.
