People often assume sprouts are best grown in jars, but the lack of circulation and the "bogging" which occurs at the bottom can spoil most sprouts within 1-2 days. While there are many other types of sprouters available with different features, the sprout bag is a perfect substitution for the jar with several advantages. Just place the desired quantity of seed into the bag, dip in water, and let sprout! Made of 100% raw hemp, this sprouting bag is machine washable and will last for years. Comes with an instructional brochure, and a care guide. Measures 7" wide x 10.5" tall.
