Deep Sprouting Tray Full Set

Want an all-in-one solution for growing microgreens and sprouts at home? This deep sprouting tray kit is perfect for families who want fresh, homegrown greens without the complexity of piecing together a system from scratch.

Why This Kit Works

Complete tray system: This kit includes the deep sprouting tray with mesh walls and base, a fitted humidity dome for germination, a pre-cut silicone grow medium for small seeds, and a scraper cleaning tool. Just add seeds from your favorite seed supplier and start growing.

Versatile mesh design: The white mesh tray features 2.5mm holes throughout—both on the base and walls. This design provides excellent air circulation for healthy root development while being small enough to hold larger seeds like wheatgrass, mung beans, and peas directly on the mesh without any growing medium.

Included silicone grow medium: The kit comes with a pre-cut silicone mesh sheet that fits perfectly inside the tray. This allows you to grow small seeds like broccoli, radish, and other microgreens without needing soil or coco coir. The silicone sheet is reusable.

Smart concave-convex design: The tray's unique design allows you to lift the inner mesh tray out without disturbing roots or greens. This makes bottom-watering simple and cleanup easier—just remove the mesh tray, rinse, and you're done.

Family-sized production: At 12.25" x 9.5", this tray provides enough growing space for a small family's weekly microgreen needs without taking up excessive counter space.

How to Use

For larger seeds (peas, wheatgrass, mung beans): Place seeds directly on the white mesh tray. The 2.5mm holes support the seeds while allowing roots to grow through for excellent aeration.

For small seeds (broccoli, radish, arugula): Place the included silicone grow medium sheet on the mesh tray, add seeds on top. The silicone holds moisture and prevents small seeds from falling through while maintaining airflow.

Bottom-watering: Fill the green base tray with water. The mesh tray sits inside, allowing roots to access moisture from below while maintaining proper drainage and airflow.

Germination: Use the included humidity dome during the germination phase to maintain consistent moisture and temperature.

Care & Maintenance

• Use included scraper tool to remove root residue after harvest
