Moss on driftwoof?

DriftWOOD, not driftwoof...


Posted this in enclosure discussion and can't seem to get any replies, so I'm reposting it here. If a forum moderator could please delete the thread in Enclosure Discussions that would be great.

Anyway, I can't seem to utilize natural driftwood in my spotted python's viv without growing moss/mold on it. The humidity is between 40 and 50 percent. I have a screen lid with tin foil covering about half of the total length of the lid, with some exposed screen on either side of the piece of tin foil for ventilation. But yet, mold seems to form on the wood. Any suggestions to prevent this?
