Grodan Gro-Smart Tray Double Sided - 78 Cells (5/Case)

The Grodan Gro-Smart Tray Double Sided - 78 Cells (5/Case) is a durable, reusable propagation tray that supports Grodan plugs and growing blocks while improving drainage, airflow, and handling during propagation.

Its double-sided design provides two useful configurations: one side features 78 individual cells for 1.5 in (3.8 cm) A-OK Starter Plugs and Macroplugs, while the reverse mesh side supports A-OK sheets, Mini-Blocks, and Gro-Blocks.

The tray is designed for standard 10 × 20 in (25.4 × 50.8 cm) propagation flats. Each case contains 5 Gro-Smart Trays.

Key Benefits

  • Durable, reusable propagation tray.
  • Double-sided design for multiple Grodan products.
  • 78-cell side for 1.5 in (3.8 cm) A-OK Starter Plugs and Macroplugs.
  • Mesh side for A-OK sheets, Mini-Blocks, and Gro-Blocks.
  • Fits standard 10 × 20 in (25.4 × 50.8 cm) flats.
  • Elevated design helps keep stone wool above standing water.
  • Promotes drainage and airflow around the root zone.
  • Supports downward root development.
  • Easy to clean and sanitize.
  • Suitable for commercial propagation and indoor horticulture.

How Does the Double-Sided Design Work?

The 78-cell side securely holds individual 1.5 in (3.8 cm) A-OK Starter Plugs or Macroplugs during propagation.

Flip the tray over to use the mesh side, which supports larger Grodan products such as Mini-Blocks, Gro-Blocks, and connected A-OK plug sheets.

This versatile design allows the same tray to support several stages of propagation and early plant development.

Improved Drainage and Airflow

The Gro-Smart Tray elevates stone wool above the bottom of the propagation flat.

This helps prevent plugs and blocks from sitting in standing water while improving airflow beneath the substrate and supporting healthy root development.
