One of the essential principles of permaculture is to make multiple uses out of every resource. In other words something that you build, or buy, or acquire or work with, isn't just useful for once, one opportunity, one use, but has various applications. Let me give you an example. This is my potting bench, I'm endlessly going through dirt, dead plants, old material, crop residues. I'm working here, so I need a place to get rid of that stuff. So I built this in-house composting system. Slide the waste in, throughout the winter I'm putting dead plants and hay and garden soil into this container. And let me explain the various uses. Number one, I'm able to have an easy way to discard my organic matter. Number two, we keep beneficial microbes and worms active all winter long. Number three, we make some delicious soil which we use in the spring to, to mix up our planting starter mix and our transplanting mix. And then finally, it yields heat, there's a small amount of heat that is produced by the compost inside the hoophouse. Now I wouldn't say it would be enough to heat the hoophouse, but inside here we're talking about small margins of temperature and if we can keep this space protected and slightly above freezing most of the winter, there's a wealth of things that will stay alive and continue to yield for us right around the calender. Now I didn't invent this idea, many people have played around with it, but it's a perfect example of how you take what you've got and convert it into something useful. In-house composting.
