I am planning on adding some plants and other things for him to hide and play under. In the meantime I am wondering if I have the kids like this if it is enough airflow.
Actually, it would be even better to cut holes out of the plastic lid for the lights, and close it completely. The lights should he hanging vertically, not at an angle, and the screen filters out a good portion of the UVB rays, making your UVB light ineffectual for the tortoises.
There is a Red foot in there. The lights aren't at an angle. Just happen to be in the picture. I thought if the lights were to close it could hurt the tortoise.
You probably want to enclose it a little more. Redfoots do best in pretty high humidity: around 80%. It's really hard to maintain that in a fully-enclosed environment, so with that much of a gap, you won't be able to keep humidity up unless you've found a way to make it rain in there every hour or two
