{"type":"firestarter.listing","listing":{"id":"lst_mrGneCrl","product_name":"Coir Discs - Set of 12","category":"Gift Shop","description":"Our favorite product to use as a medium for growing microgreens, coco coir is made of compressed coconut husks. It expands when you add water to it (which, frankly, is fun to watch!), and it makes a simple medium that is easy to work with. Expand it in a bowl and then fill the tray afterwards. One disc fills up to the \"fill line\" of one of our microgreens trays. Each unit contains 12 discs.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/files/240.png?v=1744294464","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/242.png?v=1744294464","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/Product_Squares_9.png?v=1744294540","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/Product_Squares_8_52253d84-ac67-4222-be24-a71a0f13a32d.png?v=1744294540"],"price":18.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:36.450Z"},"share_url":"https://firestarter.network/l/lst_mrGneCrl","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
