Small closet setup 27 inches wide by 50 inches deep. I have a 4 flex duct going from the A/C in the bedroom to an intake box outside the room that has a 8 fan that draws the room air and mixes it with the A/C air before it enters the closet at the bottom. In the closet I have a small humidifier that blows air right over the plants and keeps them cool. At the top of the closet I have 3 5 fans exausting the air through 3 4 flex ducts. the closet maintains 75 degrees with lights on an keeps a RH of 50%-65%.
