The complete kit includes a food-safe glass jar with a sturdy stainless steel lid that features built-in drainage. Simply soak, fill, and set it on the specially designed and fitted stainless steel rack. You can easily rinse your seeds and allow excess water to drain out over the rack onto the ceramic base. Built to last, the GEO Sprouting Jar System uses clean food-contact parts free from any BPA—so there's no contact with plastics!
