Beans are one of the easiest things to sprout from seed without any soil needed. They take approximately 3 days to spout and if you place them on a warm surface you might see sprouting activity in as little as 24 ours.
Start off with whole dried beans you purchase from a seed company or use whole dried beans you find in the organic bulk section of your store. When sprouting beans from home it really isn’t necessary to use soil. Here, I used dried Fava beans found at Whole Foods.
Place dried beans in a bowl of shallow water. You don’t need the water to be filtered. Place in a sunny location and remember to replenish water when so it’s never dry. To speed sprouting time place the bowl on your stove top when you cook in the oven, so that the seeds get warmth.
