Vents?

[BrickBonesteel]

I'm building a viv that's 48Lx20Dx18H.

How many and what size vents should I put in this thing. I live in mass so my temp range its huge, not sure if that matters. Any help would be appreciated thanks.

I don't think there is an exact science to this. Depending on how much leakage your front doors have and how many times a day you open them I would think a few square inches of ventilation would be fine. Depending on your aesthetic preferences maybe a 2 medium sized cutouts covered with screen or a few circular vents from the hardware store.
