Help!
I attended a Holzer seminar in Gimli this spring where I first learned of Kratergartens. As I am in Zone 1 anything that can give me a small thermal bump is greatly desired. Unfortunately, the seminar yielded little practical info on these systems, despite asking. But I I love the idea and have been brainstorming ever since. Perhaps that is what Sepp intended by being vague.
I have built a small model of what I think is a Kratergarten at my "research station". If any of you have done these before or have any experience please provide me some feedback... and Hey! follow me on Facebook if you'd like.
Carl Sagan, Buddha, Gandhi and Fukuoka, soon maybe even Wheaton.
