wut up cardo, firstly it wouldn't do you too bad unless you wanted the temp to be out of your control. lights get really hot in chambers, especially when closed off so having a vent hole up top since heat rises is a practical solution. look at the tents they have online on many grow sites, and if you hook that up with a inline fan + carbon control system it will handle all of your needs in terms of stealth and smell while keeping them babies in a good environment. +rep if you get a chance and ask away if you got questions.
