I have been growing for about 2 years now and have been growing in a shed with flourescents and cfls. I moved and now must grow in my closet.

setup:

400w switchable mh/hps with spider reflector (not sure brand of ballast)
closet dim. 9'hx4'wx3'd
growing one cat piss now and soon to be purple buddha (pretty stoked about the purple buddha)
a 3' tall x 8" wide floor fan on medium and osculating to really move the air around.
walls are covered in mylar
temp stays around 75-85

right now i have the the metal halide running at 24hrs for the first two weeks.
My questions are:

Is it ok to run metal halide as early as seedling stage?
How can i tell which light spectrum my lamp is operating in?
I am going to use foxfarm nutes for the first time as well for some food, when do i start feeding and how much?
Any other feed tips?
Lastly, if i tape a dryer sheet to the front of the fan would that help to control odor? not that odor is a bad thing but i live in an apt.

Thanks guys ill try to get up some pics shortly and maybe even turn this shit to my first journal.
