Edible Acres, already mentioned, is great.
Nature's Always Right is another with great content - a market garden on rented property in San Diego.
The Grassfed Homestead; Plant Abundance; are among my favourites (already mentioned).
Some have great content on specific topics I'm interested in like a playlist on raising rabbits by Living Traditions.
I'm looking for step-by-step type instructions for bee keeping and although I've found some channels about bees and learned quite a bit, there's not one that stands out for me for a beginner.
I'm in Canada and use my own seed whenever possible. For unusual herbs I buy from Richters and have had good service from them. For veggies that I don't save seed from (carrots, beets, cabbage, etc) I buy from West Coast Seeds or Veseys (East Coast). Both have given good service - haven't had to complain. I also get seeds from friends.
That was an incredible video. Had to watch it in half hour segments but well worth the effort to listen. Just amazing stuff. No wonder Paul Stamets says mushrooms can save the world. Thanks for posting it and thanks to Paul for being such a generous and ethical person.
For a cover crop that lasts the winter, I like hairy vetch. When it flowers in the spring, you can cut it back and then plant stuff. It grows thickly and helps suppress weeds. Also, there is a woman in Toronto who helps with school gardens and who has lots of ideas and suggestions of what to grow and why. Her site is http://kidsgrowingcity.ca
Thanks so much for posting your building steps and photos. Your cob shed is beautiful. Really amazing - from the roof through the wall shelves to the finished form. Your postings give me hope that I can possibly do something similar - I also am a woman and I would like to build a structure with cob. I live in a Canadian city with building codes which I'll have to check out. But I'm enthused to start some small project - maybe a playhouse for my granddaughter.
