Jiffy Plugs 7/41mm x 20
Jiffy Plugs 7/41mm x 20 are compressed peat discs that expand into ready-to-use propagation plugs when soaked in water. Each 41 mm plug is held together by a fine net, forming a self-contained growing medium for seeds or cuttings. No transplant shock — just plant the whole plug into its next container.

Jiffy Plugs 7/41mm x 20 – compressed peat pellets for effortless propagation
Jiffy Plugs 7/41mm x 20 offer one of the simplest ways to germinate seeds or root cuttings. Drop the compressed discs into water, watch them expand into full-size plugs, and you have a sterile, ready-to-use growing medium in minutes.

How Jiffy pellets work
Place the dry discs in a tray of lukewarm water. Within minutes they absorb moisture and expand into 41 mm cylinders held together by a fine biodegradable net. Insert a seed or cutting, maintain warmth and humidity, and roots develop inside the plug. When ready, transplant the entire plug — net included — into a larger pot or growing system with zero root disturbance.
Sterile peat substrate
The peat in Jiffy-7 pellets undergoes flash drying at high temperature, resulting in a clean, pathogen-free medium. No weeds, no fungal issues. The porous structure balances moisture retention with airflow, supporting healthy root development. Prefer a peat-free option? Check out the Jiffy Coco Plugs 7/35mm.
Lightweight and space-saving
Compressed discs take up minimal storage space and are extremely light before hydration. The 20-pack fits easily into a small compact propagator once expanded, making it a convenient starter set for home growers.

How quickly do Jiffy plugs expand in water?
Jiffy plugs fully expand within a few minutes when placed in lukewarm water. Once they have reached their full size, drain off excess water and they are ready for seeds or cuttings immediately.
Is the net around Jiffy plugs biodegradable?
Yes, Jiffy is transitioning to PLA netting made from polylactic acid, which is biodegradable and compostable under industrial conditions. The net holds the plug together during rooting and breaks down over time without restricting root growth.
What is the difference between Jiffy peat plugs and Jiffy coco plugs?
Jiffy peat plugs (7/41mm) use sterilised peat as substrate, while Jiffy coco plugs (7/35mm) use RHP-certified coconut coir. Coco plugs are peat-free and slightly smaller in diameter. Both expand in water and work the same way for seeds and cuttings.
