I've always wondered about air flow in a large enclosure. This is a pic of my almost finished 6' x 4' x 6' enclosure i'm currently building for my water dragons. Will there be enough air flow with a few 4' holes covered with mesh and a vent on opposite sides of the cage, or should I get a few fans. I figure the space is large enough to develop its own circulation. I wish I took physics in high school.

To create air flow in an enclosure. The vents need to be close to bottom or at least in the bottom half. The lamps will heat the air causing it to rise and thus drawing in fresh air from the vents.
