Super Sprouter Quad Thick Tray-No Hole -10″ x 20″ (Case of 25)

The Super Sprouter Quad Thick Tray (No Hole) is a 10" x 20" propagation tray built for repeated, heavy-duty use. Injection-molded at four times the wall thickness of standard vacuum-formed trays, a single tray holds its shape under the weight of wet media and stacked inserts without bowing or cracking. Sold as a case of 25, these trays are suited for commercial propagation rooms and high-volume clone operations.

Why Choose the Super Sprouter Quad Thick Tray

Standard 10" x 20" propagation trays are vacuum formed, a faster and cheaper manufacturing process that produces thin-walled trays prone to flexing and cracking under load. The Quad Thick Tray is injection molded, which forces plastic into a precision mold under pressure, yielding walls that are four times thicker than standard trays. Here is what that difference means in practice:

• No double-stacking needed. Many growers stack two or three thin trays together to carry the weight of a full tray of coco plugs or rockwool blocks. One Quad Thick tray handles that load on its own, cutting material cost and handling time per cycle.
• Longer service life. Injection-molded trays are built to be cleaned and reused across multiple propagation cycles. The increased wall thickness resists cracking from repeated flex, UV exposure in greenhouse environments, and chemical cleaners used between cycles.
• Consistent structural support for inserts. The rigid base keeps 50-cell and 72-cell plug inserts flat, which matters when moving full trays from propagation bench to rack without disturbing root development.
• Solid bottom for water retention. The no-hole design keeps irrigation water or nutrient solution in the tray, allowing sub-irrigation and ebb-and-flow use without requiring a secondary catch tray beneath.
• Case quantity for production scale. Selling 25 trays per case reduces per-unit cost and simplifies inventory. A single case supplies a modest propagation room; multiple cases cover a commercial facility.

Best Uses for the Super Sprouter Quad Thick Tray

This tray is a workhorse container for propagation and early-stage growing. Its no-hole, solid-bottom design makes it well-suited wherever water needs to be retained inside the tray rather than drained immediately.

• Seed germination. Fill with a germination medium such as a starter container setup or loose plug trays; the solid bottom holds bottom-watering moisture without a separate catch tray.
• Clone propagation. Place a neoprene or foam insert holding stem cuttings directly in the tray with a small reservoir of cloning solution; the rigid walls keep the tray level on wire rack shelving.
• Plug and rockwool block staging. Accept standard 50-cell or 72-cell insert trays; the perforated insert bottom allows drainage from the plug cells while the outer tray holds the reservoir.
• Ebb-and-flow (flood and drain) tables. The solid bottom allows the tray itself to flood and drain when positioned on a flood table, without needing a secondary liner.
• Greenhouse and nursery bench work. Durable enough for daily movement across benches and rack systems; the increased thickness prevents the rim flex that causes thinner trays to spill when carried fully loaded.
• High-volume commercial operations. With 25 trays per case, a production propagation room can standardize on a single tray spec and run consistent cycling, cleaning, and restocking schedules. For operations also managing container growing, pairing with a fabric pot for transplanted plants keeps the production workflow consistent.
