IHORT Q Plug 18/40 3/4" top X 1-1/2" deep, Case of 6,500

Engineered Square Plugs Sized for High-Volume Propagation Trays, 18/40

Uneven moisture across a propagation tray tends to show up cell by cell rather than tray by tray, since even a good starter medium can behave inconsistently if the plug shape doesn't match the tray cell it sits in. IHORT's Q Plug 18/40 is engineered specifically for balanced moisture retention and aeration, and its square profile is designed to seat tightly in standard tray cells so plugs stay put instead of shifting during handling.

At 3/4in across the top and 1-1/2in deep, this size is built for standard 18/40-count propagation trays, and the bulk case of 6,500 plugs is sized for commercial operations running continuous propagation cycles rather than occasional small batches.

Key Features & Benefits

• 3/4in top, 1-1/2in deep — sized for standard 18/40-count propagation tray cells
• Engineered moisture retention — balances water and air to support optimum rooting conditions
• Square plug shape — seats tightly in tray cells to reduce shifting during handling
• Bulk case of 6,500 — sized for continuous commercial-scale propagation runs
• Supports cuttings and seeds alike — works for both cutting propagation and seed starting in the same tray system

Who Should Use These Plugs

Commercial propagators running standard 18/40-count trays at volume, who need a consistent, tightly seated plug shape across thousands of cells per order, are the best fit for this bulk case size.

About IHORT

IHORT produces the Q Plug line of engineered propagation media, offered in square and round formats matched to standard cloning and seed-starting tray configurations.

Frequently Asked Questions

What size are these plugs?

Each plug measures 3/4 inch at the top and tapers to 1-1/2 inches deep, in a square shape sized for 18/40-count propagation trays. The taper helps the plug seat securely within its tray cell.

How many plugs come in a case?

This is a bulk case of 6,500 square starter plugs, sized for high-volume commercial propagation rather than small trial runs. Smaller-count cases are not part of this listing.

What is this plug engineered to do?

It's engineered for balanced moisture retention and aeration, so cuttings and seeds get consistent access to both water and oxygen at the root zone. That balance is what supports even, optimum rooting across a full tray.

How should I use these plugs when starting a propagation run?

Saturate the plugs before inserting cuttings or seeds, then keep them consistently moist through the rooting period rather than letting them dry out between waterings. Because the square shape seats tightly in tray cells, plugs are less likely to shift or tip during regular handling.

Can these plugs be used for both cuttings and seeds?

Yes, the same engineered moisture-and-aeration balance supports both cutting propagation and seed starting. Many commercial operations run both in the same tray system using this plug size.
