So, I'm guessing I can just pit my seedlibgmat on top of a cardboard box. However I put a plate of granit on top of the box, and the mat sits on it. That should be safe right? Any dangers on putting it on a box? I'm guessing it gets to90-96 max. I'm guessing as long as it's not on carpet its fine. Seems Like a stupid question until you just pliggednit in, went to am/pm, and On your way back saw fire trucks.
