Step 3: Store the beans in a jar covered with cheesecloth to allow air to pass through. You can place them in a dark area while waiting for them to sprout. Store them in the dark area for 12 hours, it doesn’t have to be the darkest area, a shadowy area will suffice. Why do mung beans grow faster in the dark?

If you don’t have the test kit, you can combine water and baking soda then pour it in soil. Bubbling indicates that it is acidic and will be good for your beans. PH testing kits can be found in online shops, and in your local agricultural shops.
