I've always made male chambers out of see-through storage totes, just prop them on the side, cut an intake and an exhaust with a computer or squirrel fan, and use either snips of hepa or double stacked hvac filters to cover your intake/exhaust to limit pollen. since the tub is clear you can leave it in the room with the girls, and take it outside the room to open the lid and water. I even had drip tubes going into the box so I could funnel water without coming into contact...works great if you need a little pollen or s1 project on the side without being disruptive to your normally scheduled activities.
