Grow your own sprouts at home easily! Whether you are a novice or an expert, sprouting trays make the experience easier. This 4-Tray Seed Sprouter produces nutritious sprouts in just 3-5 days. Simply spread the seeds in each tray and pour water in the top tray. As the water slowly siphons through the tray below, the seeds are gently soaked to start the germination process. The four, 6" diameter sprouting trays, allow you the versatility you need by letting you grow the same sprouts in each tray for a large batch, or grow 4 different varieties at once. The BPA free plastic is dishwasher safe and easy to clean by hand.
