Yeah, I'm just gonna nail the ply wood down over the window... I am going to be fixing plenty of holes either way when I move out (some as large as six inches) A little cillicon would fix the holes from the ply wood being put on in a matter of minutes. Kudos for the help bro.

Also really liking your idea about taking an inch off my door frame at the bottom, unfortunately... unless someone knows a way to install some sort of screen or what not (and not have it look obvious there's a grow room inside) I'm afraid the pests would jump off the cats and end up in the room. Already having a mite problem, so naturally I'm constantly trying to figure out ways to prevent those fuckers... one of which is not touching the cats as much and washing my hands.
