He usually goes by JM Fortier on YouTube and I think he’s great. He’s a real inspiration to me, for sure. He’s very open and has a lot of stuff up there on various channels about the development of his market garden.
He’s great if you want to garden as a business, but if you have a bit more flexibility and time, I’d recommend permaculture as a sustainable and lower cost starting point. Bio—intensive farming like Fortier advocates is great but more expensive to start.
