Thanks for the replies. I started to connect the dots and ill see how that goes. Im going to put velcro on the outline on the part of the wall that comes out and cut a piece of wood to fit it for easy access for waterings, etc. Ill have a hole cut in that piece of wood(watever it is i find to use) and a vent on that. For the intake i have some holes drilled, and im gonna wire a comp fan for the intake and I already have a fan for exhaust.
Since my space is limited can i have that fan on the other side of the vent? Sucking the air from inside the cabinet. My beans are still on the way so ill have some pics of the completed project in a week or so, that way i can get the proper expertise to make sure everything goes smoothly.
