I am looking for a bit of ventilation/odor control help. I am dedicating a portion of a workshop to cultivation (it already has a wall dividing it in half). The measurements in the part Ill use are 12 X 8, with a height of 8 feet, sloping to 7. As such, the cubic area is about 720 ft3. Since this is an entire room and wholly separated from the house, I am thinking that I can use either a ceiling or wall exhaust fan (or even exhaust into the other half of the shop for added stealth) and maybe use a hole near the floor for inflow.
However, using the 3-5 per minute rule for refreshing the air supply and helping to control temperatures, we are talking 2160-3600 CFM for Gods sake. Even finding an exhaust fan of this side leads you to somewhere like Grainger and, when found, aint cheap. Were talking about $350 for a 2,000 CFM model. But, if that is what it takes, I guess that is what it will be. What does anyone else do with a room of this size? And what about the inflow and exhaust holes? How does one control light? I can see maybe running angled duct work for the inflow but I was not planning to use ductwork for the outflow .
Second, but just as importantly, what about odor control? I MUST have excellent odor control given the location of the shop in juxtaposition to my neighbors. The in-line, ducted filters are easy to find, but what does one do if using a wall or ceiling fan?
I am hoping I havent bit off more than I can chew, or afford, by having the luxury of such a big space. I mean for a small little closet, there seems to be info out the ears, but not for larger areas. Maybe I need to look at sites more concerned with vegetable gardening. (?) Any advice considered, even with respect to topics I might not be considering. Thanks.
