Hey RIU. This is my first post/thread on the forum, but I've been lurking a while and trying to absorb tips and tricks from the many rock stars on this site. What I'm planning would not be my first grow, but my first indoor grow in about 10+ years, so I can more or less be considered a n00b. I have a dresser/armoire(sp?) in my bedroom that measures is 35.5" wide, 19" deep, and the height is divided into a 42" top section with two removable peg shelves, and a bottom section with two 9" deep drawers. Obviously the shelves are coming out, and I'm also planning on removing the drawers and just gluing and/or nailing the front of the drawers back onto the bottom. Now, the plan is to pop a 400w HPS light in there for, ideally between 3-5 plants. So it shouldn't be much of a surprise that my primary concern is going to be heat and venting. I live in the Northeastern US, and the ambient temperature in the room the dresser is in is currently quite brisk, maybe 65ish, 70 tops even with the heat on, but with the growing schedule I have planned, I'd be harvesting my first crop in late May, early June, when the outside/room temperatures will be significantly higher. My wife has given me her blessing to grow in our room and I don't have to be super stealthy, but she has forbidden me from putting any holes in the walls or ceiling (so no venting to the attic!). I've never used an HID before, so ventilation is new and confusing to me. I would love any input would be appreciated as to whether my plan is feasible, and, if so, how do I make this work? To give ya'll an idea of what I'm working with, here are some 3d models I made on sketchup: This is the cab, with the lamp hood (air cooled) that would be housed in it. There are two doors to the front of the cabinet that I just didn't feel like including in the model. I also didn't include the back, which is cheap, thin pressboard that I am planning on taking off and replacing, if for no other reason than to have a sturdier and more lightproof backing. I was actually thinking about building an extended backing so I could probably increase the depth by up to 6". View attachment 2495526 Heres an angled view of the cab. View attachment 2495533 Here's a view with the drawers and bottom-most shelf removed. I have no issues with removing, drilling, or cutting into any part of the armoire, especially for the sake of ventilation, as long as it looks pretty much like an armoire at a passing glance into our room. Basically, this means, little or no modifications to the front or right side of the cab. Idgaf what the back or left side really looks like, but a ton of flexible ducting coming out like a robo-kraken would be less than ideal.

Thanks!
