Growing Moss on Clay Pots?

I'm going to try your recipe for growing moss on clay pots, but have a few questions. 1. How long do you leave the pots in the plastic bags? 2. Can the pots be planted after eight weeks and can they remain in full sun or do they need shade? 3. Do the pots, with moss now growing have to be misted everyday? 4. Can they remain outside for the winter and will they start growing moss again in the spring?
