This BPA-free, food grade plastic lid fits most wide mouth jars (including Mason), and has a fine mesh screen to let water out and oxygen in. The Plastic Sprouting Screen is dishwasher safe. Add a spoonful of sprouting seeds to your wide mouth mason jar, screw on the plastic sprouting screen, and you are ready to grow fresh nutritious sprouts in as little as four days.
The plastic sprouting screen is an excellent entry level, rudimentary piece of sprouting equipment, and may be the only sprouting equipment you will ever need.
