The general recommendation over on the 3D printing discord server is to buy and put your resin printer/wash station/resin tools in a "grow tent"--designed for growing plants indoors these a super useful for resin printing if you can find one for a good price (check ebay, they'll usually be cheaper there). There are a lot of sellers for these--many of which come designed specifically with a hole for ventilation hose (sometimes they even come in bundles with tubing and an extraction fan). The doors can be zipper closed and the inside is usually covered in insulating material to keep the temperature at a constant temperature. They are also opaque and sunproof, no risk in putting it close to a window and risking uv exposure from sunlight.

Heads up, the pictures make it look smaller than it is, go by the measurements.
