**Q: Is this safe for terrariums?**
A: This is a food safe silicone sealant that many use for aquariums so it should be fine for a terrarium.  It is definitely waterproof.

**Q: Does this product have a shelf life?**
A: Any RTV product I've ever used eventually dries up if not used within a period of time but i'm not sure how long that takes. You should only buy what you think you'll need for the job. They make this in a smaller tube if the calk gun size seems too much.
