The Garden's Alive. 2-Tiered Indoor Seed Sprouter is an easy-to-use Seed Sprouter that allows for viewing and monitoring of seeds and sprouts. 2 trays are included in each kit, allowing you to grow a different kind of sprout on each tray. Each offer includes 2 trays for sprouts, but you can add up to 4 trays for a single unit. Seeds for sprouts are not included in this offer and are sold separately so that you can decide which sprouts you'd most like to try. We recommend Gurney's Sprouting Seeds, but whatever you choose, growing sprouts makes a great project to share with your entire family. No soil or sunlight is needed to grow delicious, nutritious sprouts--just water and time.
