So I've been thinking of spicing up the little boa cages in a test for the big boas and Caesar. I want to put in some silk vines again and would like to put in a nice piece of driftwood. My question is last time i did driftwood years and years ago on a coco substrate, the driftwood started molding all around where it contacted the coco. How do you guys keep your driftwood from molding short of suspending it like perches?
