will this setup work

this is my first grow by myself. my other grow was with the help of a friend, an i jus wanna if i should add sum mods. any advise would be helpfull, than

i don't see much ventalation going to need a small fan in there. lights ventalation and a fan the bread and butter of growing. could be a nice setup if you get it right

I would remove the foil from the door, and just paint them with flat white paint, it relects 90% of the light. The other thing would be to add two small computer fans, one for intake one for exaust.
If you dont have the fans try e-bay under muffin fans, there stong and cheap and can be wired togther to use only one plug.

hey man its gonna suck if you spend all you time on one plant and then it turns out to be male. plant a couple more. youll need more CFL lights and some air flow.
good luck

your box doesnt look that tall, your gonna have to get a taller one or more likely make sure that bitch (assuming your lonely plant will be a female) doesnt grow too tall. good luck though
