The AeroGarden® Seed Starting System for the AeroGarden® Sprout allows you to grow up to 15 seedlings that you can easily take out of your garden and transfer to your outdoor beds when the soil is ready. To get started, simply place your favorite seeds in the included Grow Sponges, then watch the seeds germinate over time. Once the weather allows, take your seedlings out of your garden and plant them outside. Our Seed Starting System design promotes healthier root development, and makes removing and transplanting seedlings easier than ever. Your Sprout model AeroGarden® will nurture your seeds with optimal amounts of water and plant food, and provide plenty of light and warmth for reliable germination and healthy growth. The AeroGarden® Seed Starting System for the AeroGarden® Sprout comes with one reusable plastic seed starter tray, 15 biodegradable Grow Sponges, one 3 oz. bottle of plant food, and our Seed Starting & Transplanting Guide.
