Cloning Tray Rockwool Paperbus 34
The Cloning Tray Rockwool Paperbus 34 contains 84 rockwool plugs with a 34 mm diameter, each wrapped in a protective paper sleeve. The sleeve holds the plug together during rooting and breaks down naturally after transplanting. A practical choice for fine-stemmed cuttings and small seedlings. Order at Plant & Flower.
Cloning Tray Rockwool Paperbus 34 – paper-wrapped plugs for gentle propagation
Not every cutting needs a large plug. The Cloning Tray Rockwool Paperbus 34 provides 84 rockwool cubes at 34 mm diameter, each encased in a paper wrapper that keeps the plug intact throughout the rooting stage. Check out our full cloning and propagation category for all available substrates.
Paper sleeve: easier transplanting
The paper casing around each plug is what sets the Paperbus apart from standard rockwool trays. It holds the cube together even before roots have fully formed, reducing the risk of the plug falling apart when handled. At transplant time, place the entire plug — sleeve included — into your growing medium. The paper degrades on its own without restricting root growth.
Compact 34 mm format
At 34 mm, these plugs are smaller than those found on a typical Grodan 77 Plugs tray. This makes them well suited for thin-stemmed cuttings and small seeds that don't require a large substrate volume in the early stages. The tray holds 84 plugs, giving you a solid batch size for a single propagation round.
Try alongside organic options
Curious about organic propagation media? The Root Riot 24 Cubes offer a composted alternative that some growers prefer for certain plant varieties. Running a small side-by-side comparison can help you determine which medium delivers the best results for your specific needs.

Do I need to remove the paper sleeve before transplanting Paperbus plugs?
No, the paper sleeve can stay on the plug during transplanting. It breaks down naturally once in contact with moisture in your growing medium. Leaving it on actually helps protect the developing root system during the transfer.
How many plugs are included in the Rockwool Paperbus 34 tray?
The tray contains 84 rockwool plugs, each measuring 34 mm in diameter. They come pre-arranged on a single tray and are ready for use after a brief soak in pH-adjusted water.
What is the difference between Paperbus plugs and standard Grodan rockwool plugs?
Both use rockwool as the substrate, but Paperbus plugs have an additional paper wrapper around each cube. This makes them sturdier to handle and easier to transplant. Standard Grodan plugs sit on a connected sheet, which is better suited for tray-based propagation setups.
