Hi, my name is Mark. If you wonder if I live on Mars, well not exactly. I live in the wilds of the USA. However, I grow plants that could grow and survive on Mars! I specialize in sweet potatoes & American native seeds. I grow and cultivate my plants in my garden and they've adapted to harsh conditions here: extreme heat, frost, humidity, drought, and sandy soil. Most are permaculture. I don't use soil amendments. So those that have survived have adapted to Martian-like conditions. I am a US grower and focuses on survival foods. My other job is I am getting a Ph.D. in economics. I grow food for my family in my fields and sell things of value to others for extra income that we need at this time. We are not a commercial farm and believe in innovative sustainable agriculture. Everything is grown beyond organically. Let me know if you have any questions or ways I can help. I know a lot about growing. Thank you sincerely, Mark Biernat
