Curtis Stone, the Urban Farmer, and JM Fortier, the Market Gardener, are both are highly influential sustainable agriculture experts who are educating others about six figure income farming (how to make growing food profitable without expensive machinery). Their ideas can be scaled up or down. You can use their ideas in your back yard or on a commercial farm. They both offer a ton of free information on their websites and YouTube channels. I’ve already spent hours immersed in their sites absorbing as much as I can.
