Jiffy Peat Pellet Refill Pack - 36mm - 36ct

Loose 36mm Peat Pellet Refills for Jiffy Greenhouse Systems, 36ct

Running out of peat pellets partway through a busy propagation season means either pausing or scrambling for a substitute that doesn't match your existing trays and domes. Jiffy sells its 36mm peat pellets separately from the tray-and-dome kits, so growers can restock exactly the pellet size their existing Jiffy system uses without buying a whole new kit.

This 36-count refill pack restocks a 12- or 24-cell Jiffy Windowsill Greenhouse or a 36- or 72-cell Jiffy Professional Greenhouse for home gardeners and hobbyist growers running smaller, occasional batches.

Key Features & Benefits

• Loose 36mm peat pellets — no tray or dome included, sized to restock an existing Jiffy system.
• Expands with water — the same compressed-pellet mechanism as Jiffy's complete kits.
• Direct transplant — the whole expanded pellet goes into the ground with the seedling.
• Available in bulk or smaller refill quantities — match order size to how often you're starting seeds.

Who Should Use This

This fits growers who already own a Jiffy tray-and-dome system and need to restock 36mm pellets, whether that's a home gardener running occasional batches or a commercial propagation operation going through pellets continuously.

About Jiffy

Jiffy is a heritage seed-starting brand under Green Garden Products, best known for the Jiffypot biodegradable peat pot that transplants directly with the seedling inside it. Its peat pellet refills use the same direct-transplant netting and peat composition as Jiffy's complete greenhouse kits.

Frequently Asked Questions

How do I use loose peat pellet refills

Place the pellets in your existing Jiffy tray, add warm water, and let them expand fully, the same process as pellets that come packaged with a complete kit. Once expanded, sow seeds directly into the top of each pellet.

What Jiffy systems do these refills fit

36mm refills are sized for 12- and 24-cell Jiffy Windowsill Greenhouses and 36- and 72-cell Jiffy Professional Greenhouses. Confirm your tray's cell count before ordering to make sure the pellet size matches.

Should I buy the bulk box or a smaller refill pack

The 1000-count bulk box suits commercial-scale propagation running through pellets quickly, while a smaller refill pack fits home gardeners restocking a single tray between seasons. Order size mainly comes down to how many batches you're starting and how often.

Can I plant the expanded pellet directly into the ground

Yes, the biodegradable netting and peat composition break down in moist soil, so the whole pellet transplants with the seedling and roots keep growing undisturbed. That's the same direct-transplant design used across Jiffy's pellet-based products.
