It is possible to purchase a kit specifically for growing sprouts at home, but for most people this is an unnecessary expense. Spouts can easily grow in a canning jar and will taste every bit as good as those grown in a specialized sprouter. Other than a canning jar and ring, no other equipment is needed for growing fresh spouts at home.
Wash and thoroughly dry a one-quart canning jar.
Cut a three-to-four-inch square from the leg of a nylon stocking or a pair of pantyhose.
Measure one tablespoon of alfalfa seed or two tablespoons of any other type of seed you plan to sprout. Pour the seed into the dry canning jar.
Fill the jar halfway full of warm, but not hot, water. Stretch the square of hosiery over the opening of the jar and secure in place by screwing on the canning ring. Set the jar upright on the counter top overnight.
Drain the water from the sprout seeds the next morning. Rinse the seeds by filling the jar with fresh, cool water and drain. Repeat a second time.
Set the jar into a saucer or shallow bowl sideways with the opening facing into the bowl. This allows any extra water remaining in the jar to drain.
Rinse the sprouts twice daily until they reach the desired size. Alfalfa seeds are generally ready in four to five days, while other seeds may take a week to 10 days.
Rinse and drain the sprouts a final time and store in the refrigerator until needed.
