I am in the process of building a new enclosure for my red foots. It will be 10' by 4' by 3 1/2'. It will be a closed wooden enclosure with sliding front doors made of plexiglass. Will this hold enough humidity just by misting and keeping moist substrate under a dry layer of mulch? I've read a lot about people using false bottoms with heating elements and water to create humidity. Is this necessary?
