We are planning to use cypress mulch as a substrate with terracotta pots for hides. Will this provide enough rough surface for a nice normal shed or should be plan on introducing something else during shed times (Punkin the new snake apparently doesn't shed "cleanly" but I'm thinking that may be humidity issues as it's been kept in a glass case set-up as far as we know and will go into a Rubbermaid bin system when arrives here).
