When the Red Worm Composting group was still active on Facebook, I was one of the most active contributors. I found myself answering the same questions over and over again. Scott's Vermi Adventure is a blog where I can post answers to often asked questions about raising composting worms.
Someone in the Redworm Composting group wanted to know how many worms he would need if he wanted to remove 10 pounds every day. Being both a worm geek, and a math geek, I came up with the answer, along with the formulas to answer similar questions. From there, I created the worm calculator.
