I created a compost bin and put worms inside it. I put the lid on top with holes in it. I came down one day, and worms had crawled out of it, up and through the sides. Even after putting some weight on top. I also noticed mold growing inside. So I keep an LED light on it all the time to prevent the worms from coming out, but now I fear I am only worsening the mold problem. Any ideas on how to properly run this thing?
