First of all the greenhouse will have to have a hard base to stop anything burrowing out. You can do this by either laying slabs or by putting down fine galvanised mesh underneath whatever substrate you choose to use.
If you don't want to use turf I would recommend top soil and moss as a substrate, you can get a plant from your local garden centre called "none of your business" that is a very good hardy ground covering fern / moss.
