Thabks everyone!! Just making sure!!Not a fan of the wood hides. They mold almost no matter what. As far as mold goes, most substrate (especially for moist sp) molds when it is new. I use a mix of cocofiber, but when I was new I used only cocofiber, and whenever I used stuff from a newly hydrated block it would mold and eventually resolve itself. I haven't had any issues with Ts being affected by run of the mill green mold.
