Hi, I’m building a new enclosure for my 2 marginated tortoise. If I use a pond liner or flex seal to water seal the wood, could mold develop at the bottom of the enclosure?
Just keep your enclosure free of old food and waste. Good cypress mulch changed every 3-4 months. Spot daily cleaning. And FlexSeal is what I used on my enclosure - all corners, sides, etc. then I used a heavy duty shower curtain then some rubber mats. Never had a problem with mold or mildew at all.
