Evaporation cools, that's why damp terracotta for the outside pot is a 
good idea if you're trying to keep things cool. If you're trying to keep 
them warm, reducing evaporation is the game.

In the very cold years here, I noticed that seedlings sealed in plastic 
bags survived, whilst those exposed to the air in the greenhouse did 
not, I put that down to lack of evaporation.

Whether putting your pot of seedlings in a plastic bag and tying a knot 
in it is a good idea is another matter.
