Super Sprouter Quad Thick Propagation Tray - 10in x 20in - with Holes

Super Sprouter Quad Thick Propagation Tray for Reliable Clone and Seedling Production

The Super Sprouter Quad Thick Propagation Tray is injection molded - not vacuum formed like most standard 10in x 20in trays - resulting in a tray that is four times the thickness of regular propagation trays. No need to double-stack trays for extra support: a single Quad Thick tray provides the rigidity to safely carry a full load of inserts, plugs, and growing media. Drain holes allow excess water to flow through freely, preventing waterlogging and keeping root zones healthy throughout propagation.

Key Features & Benefits

• Injection molded - Quad Thick construction - Four times the wall and base thickness of vacuum-formed trays for exceptional rigidity, load capacity, and long-term durability.
• Drain holes - Allows excess water to drain freely, preventing waterlogged root zones and supporting healthy development.
• Compatible with Super Sprouter dome and insert systems - Pairs with Super Sprouter 72-cell and 50-cell inserts and humidity domes for a complete propagation setup.
• Rock wool, coco plugs, and soilless media compatible - Works with Grodan A-OK stonewool starter plugs, coco plugs, and all standard soilless mixes.
• Reusable construction - The quad thick build withstands years of repeated use, cleaning, and sterilization cycles.

Who Should Use This

Standard 10in x 20in footprint compatible with Super Sprouter 72-cell and 50-cell insert trays and all standard 1020 humidity domes. Works with Grodan stonewool plugs, coco plugs, peat pellets, and soilless starter mixes.

Frequently Asked Questions

What makes the Quad Thick tray different from a standard tray?

The Quad Thick tray is injection molded - a process that produces thicker, more uniform walls than standard vacuum-formed trays. The result is a tray four times as thick that does not flex or crack under load, eliminating the need to double-stack trays for stability.

Do I need a separate catch tray with this tray?

For a fully contained system with bottom watering or runoff collection, pair this draining tray with a Super Sprouter or standard no-holes tray placed underneath.

What media is this tray compatible with?

Super Sprouter propagation trays work with rock wool (stonewool) starter plugs like Grodan A-OK, coconut coir plugs, peat pellets, loose seedling mix, and all common soilless propagation media.

What dome and inserts fit this tray?

The standard 10in x 20in footprint is compatible with Super Sprouter humidity domes, the Super Sprouter 72-Cell Insert Tray (HGC726220), and the Super Sprouter 50-Cell Plug Insert Tray (HGC726227).
