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

Quad Thick Injection-Molded Tray for Clone and Seedling Propagation — with Holes

Injection molded — not vacuum formed like most standard 10in x 20in trays — Super Sprouter states this results in a tray four times the thickness of regular propagation trays. No need to double-stack trays for extra support: a single Quad Thick tray is built to carry a full load of inserts, plugs, and growing media. Drain holes allow excess water to flow through freely, helping prevent waterlogging and keeping root zones healthy throughout propagation.

Key Features & Benefits

• Drain Holes: Allows excess water to drain freely, helping prevent waterlogged root zones.
• Compatible with Super Sprouter Dome and Insert Systems: Pairs with the Super Sprouter 72-cell and 50-cell inserts and humidity domes for a complete propagation setup.

Frequently Asked Questions

What makes this tray "Quad Thick"?

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 Super Sprouter states is four times as thick, which doesn't flex or crack under load and eliminates 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 no-holes tray placed underneath. The two trays together form a complete sub-irrigation setup.

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, and loose seedling mix. Any common soilless propagation media suited to a standard 1020 footprint will work as well.

When would I need the Super Sprouter insert trays with this tray?

Use the Super Sprouter 72-Cell or 50-Cell Insert Tray when starting individual plugs or seedlings, since both fit this tray's standard 10in x 20in footprint. Add a humidity dome on top for a complete propagation setup.
