Instructor: Robert Pavlis Fee: $10 (plus HST) per person The previous workshop provided information about the composting process. This workshop is more hands on and looks at various methods for completing both hot and cold composting. Hot composting is the traditional method using one or more bins. This is a great system that makes faster compost, but it is impractical for smaller gardens. Various plastic bins and drums are more suitable there. We’ll have a look at various commercial and DIY systems.
