Q-Plug 1.5" x 1.5", Round, Case of 1200

Composted Peat-and-Bark Plugs Built for Early Root Development, 1.5in Round

A starter medium that fights a cutting instead of supporting it usually shows up as slow, uneven rooting across a tray, especially when the medium is either too dense to let roots push through or so loose it dries out between waterings. Q-Plug round starter plugs are made from naturally composted organic peat and bark that already carries beneficial fungi, giving cuttings, clones, and seedlings a medium that holds a workable air-to-water ratio from the first watering.

This 1.5in round format, sold in a bulk case of 1,200, is sized to drop directly into Rapid Rooter tray cells and Hydrofarm cut kit trays without any modification, making it a straightforward fit for growers already standardized on those tray systems.

Key Features & Benefits

• Composted organic peat and bark — naturally contains beneficial fungi to support root health from the start
• Balanced air and water ratio — the composted structure holds moisture without staying waterlogged
• Compostable construction — breaks down naturally after transplanting instead of persisting in the growing medium
• Fits standard trays — sized for direct use in Rapid Rooter tray cells and Hydrofarm cut kit trays
• Bulk case of 1,200 — sized for commercial-scale propagation runs rather than small trial batches

Who Should Use These Plugs

Commercial propagators and grow shops running high volumes of cuttings or seedlings through standard tray systems will get the most value from buying Q-Plug in this bulk round format.

Frequently Asked Questions

What are Q-Plug round plugs made from?

They're made from naturally composted organic peat and bark, which already contains beneficial fungi that support root development. No synthetic foam or mineral wool is used in the base material.

Which trays do these plugs fit?

They're sized to fit Rapid Rooter tray cells and Hydrofarm cut kit trays without trimming or modification. Check your tray's cell dimensions before ordering if you're using a different tray brand.

How do I use these plugs for cuttings or seedlings?

Saturate the plugs with water, insert a fresh cutting or seed, and keep the medium consistently moist through the rooting period. The composted peat-and-bark base holds enough moisture between waterings while still draining excess water.

Can these plugs be inoculated with other biological controls?

Yes, the compost base can be inoculated with additional biological controls if a grower wants to layer in a specific beneficial microbe strain. The naturally occurring fungi already present provide a baseline level of root support on their own.

Are these plugs compostable after use?

Yes, they're made from naturally composted material and break down over time rather than persisting as plastic foam does. Once a rooted plug is transplanted, the plug itself continues composting in the surrounding growing medium.
