Large Sprouting Tray Full Set

Large Sprouting Tray Set with Silicone Reusable Grow Medium

Crafted from thick, durable BPA-free PP (polypropylene) plastic, this large sprouting tray set is designed for growing microgreens, sprouts, and grasses with or without soil. The included silicone reusable grow medium sheets allow you to grow smaller seeds—such as broccoli—without relying on coco coir or soil.
