Jiffy Propagation Pellets — Peat Compressed Plug

Jiffy Propagation Pellets — The Classic Peat-Compressed Plug

Jiffy pellets are the classic propagation medium — compressed peat plugs wrapped in a fine mesh net that expand to 7× their size when soaked in water. Ready-made seed and cutting substrate with optimal pH and air-to-water ratio built in. Add water, pop in your seed or cutting, and you're done. Industry standard for decades for a good reason.

Why growers choose Jiffy pellets:

• Expands 7× when soaked — compact dry, full-size wet, minimal storage space required
• Pre-adjusted pH and nutrient balance — optimal conditions for germination out of the box
• Net-wrapped for structural integrity — holds its shape through watering cycles
• Optimal air-to-water ratio — seeds and cuttings get both oxygen and moisture they need
• Transplant with the plug intact — minimises transplant shock, roots grow through the mesh naturally
• Industry-standard for decades — if it didn't work, growers would have stopped using them
• Works for seeds, cuttings, and tissue culture — universal propagation medium

Who it's not for:

For coco-based final grows, Plug Life Coco trays match the final medium better — less transplant transition shock. The mesh wrap occasionally restricts root growth for some plants; if you see roots circling the mesh, slice the mesh before transplant. Not suitable for strict-organic certification setups unless specifically labelled as organic-certified.
