Fold over paper towel and place in food bag.
1 bag Food storage bag
Keep bag at 77°F (25°C) or a bit lower, replenishing moisture as needed using spray bottle. A heat mat with a thermostat is helpful for this. At lower temperatures (70°F ish or 21°C), seed sprouting will be slower but can still work.
