It's a good start with that closet.

For soil I would recommend something without fertilizer in it at least to start your seedlings in. If you have Promix or Sunshine Mix #4 around, then I would definitely use that. If you don't, then use grandma's potting soil with the dirt and sand.

The ventilation is what caught my eye when reading your post. Even if you got 120mm fans that were 100 CFM each, I don't know if it would be enough for that closet size. Have you read about cool tubes? If you built one (easy-medium thing to build, costs $20 or so), it will keep your closet SOOOOOOOOo much cooler. The 400w will heat that closet up so fast unless you have a good ventilation system.

For nutrients, have you checked out the GH-3 part nutrients? General Hydroponics makes a 3 part (micro, grow, bloom, or something like that) that I have heard good things about. GH-3 with molasses and Epsom salts is all you should need.

The HPS can be used through all the plant's life but I would recommend that you buy some CFLs to start the seedlings off with. You can just get a desk lamp with a cool CFL in it to start them growing. Once they are about 4" (verification please), then put them under the HPS with about 2' (verification please) between the light and the seedlings.

Other than that, it looks ok to me. WW is a nice strain and the 1.5 ft of depth shouldn't be too bad for em. You could grow 4 plants with the 400w easily as 400w covers 3'x3'-5'x5'. I would suggest you germinate 5/10 of the seeds you get and save 5 just incase.

That is about it for now. Looks good and looks like you have read up on growing, :thumbsup:.
