I read about this guy that lost his job, but he had a bunch of seeds. He didn’t have a big yard, but he took the seeds and started a bunch of them.
Then he took the plants to farmer’s market/ flea market type places and sold them. Made enough money to survive, expanded, and works full time in his own business now.
IIRC he also sells plants to various large stores now.
I think in my case, selling seed packets would work better than selling live plants. Don’t get me wrong, there’s a good demand and a nice markup on live tomato plants. But, I have no place to grow them where they’d be safe from both cat and family. And, I’ve been mute for almost 2 years, it would be very hard for me to sell anything in person. Seeds I can sell online and send though the mail.
