This is probably the most expensive online book I've bought. Still don't know for what I paid $745. I already read a book about permaculture, also watched some YouTube videos, but the course didn't teach me anything new. Actually I picked more up on Youtube. The whole course was just a lot of reading with no effort to create an interesting learning process. One video at the beginning, with very little to go on. Well ...learning by doing.
