I thought I'd post some pics of the wardrobe closet I use to propogate jewel orchids and tropicals for the dart frog tanks, as well as breed mice in, since some of you might like the idea of keeping breeding rodents out of sight and smell. I'm using one of the carbon filters I posted plans for last month. It was $100 at Ikea and the shelves are $20 for 2. I plan on buying 2 more shelves and spacing them better to breed rats and more mice. I currently only have 2 - 0.2 groups with a male who gets moved through them both every other week. There's constant, fresh air flow and the output smells clean. The closet is large enought to fit 3 - 10gal tanks or 4 large critter keepers per shelf. The bottom half isn't currently being used.
