What's a Johnson-Su Bioreactor then?

Today we dive into the wonder that is the Johnson-Su Bioreactor exploring the why, how, what and wheres of building this microbe and mycelium making composting system. We talk through the benefits for soil health and find the step-by-step construction amazing. Unlike the name suggests, this isn't rocket science and actually an easily built little system that will sit quietly on the plot for a year, busily making the most beautiful compost inoculant. There's little else discuss other than the weather : )
