Lovely project. I hope to visit Huai Phueng some day. Also please talk with nostr:npub19hs0lg9vyd0lghayeju5fnflx0melawjrl8etuqln9gkhd4mwtxq2t5jcn who is facing some similar challenges. His father also have diabetes, and changing something with food, exercises and so helped him a bit too. We found the info by the internet. Now they are using their garden for Permaculture farming. He tries to orangepill shops in his local village too, but I think he can use some knowledge by you how to talk with the merchants.
