I think growing the Ganoderma lucidum mushroom, which I see in the photos, would be a useful addition to your agricultural business. :)
This mushroom, as far as I know, is cultivated in Southeast Asia and is considered medicinal. You can't eat it because it's very tough, but it's not always used for making soups and stews. LOL.
About forty years ago, I often found these mushrooms in the Moldovan forests. They were a beautiful gift from the forest, as if they had been coated with a layer of varnish.
