PlantBest Jumbo Coconut Coir Refill Pellets - 50pcs - 42mm

Larger-Volume Coir Growing Cells for Bigger Transplants

A pellet with too little volume runs out of root room before a seedling is ready to transplant, forcing an earlier move than the grower planned. PlantBest's Jumbo Coconut Coir Refill Pellets pack more coir fiber per disc than a standard pellet, so each 42mm jumbo pellet holds more root-development space once expanded with warm water.

The 50-piece pack restocks a PlantBest greenhouse system for additional propagation cycles, sized for growers running larger or repeated batches through a season.

Key Features & Benefits

• Jumbo pellet volume — more coir fiber per disc than a standard pellet supports bigger root systems and larger plants before transplant.
• Expands with warm water — compressed pellets swell into ready-to-use growing cells with no separate media to fill or prepare.
• Fine mesh netting — holds the expanded coir together during propagation and breaks down naturally in soil after transplanting.
• 50-piece refill pack — restocks a PlantBest greenhouse system for additional rounds of seed starting or cutting propagation.

Who Should Use This

Growers who want more root-development volume per pellet than a standard-size disc provides, or who are restocking a PlantBest system for another propagation cycle, get the most from this 50-piece jumbo pack.

About PlantBest

PlantBest specializes in coconut coir. It's a growing and propagation medium. Coir is peat-free by nature. The fiber comes from coconut husk byproduct. That's different from harvested peat bogs. The catalog spans loose-fill coir and compressed pellets. It also includes coir pots and supporting trays. Growers use domes through germination and early growth.

Frequently Asked Questions

What makes these pellets 'jumbo' if they're also listed at 42mm?

The jumbo pellets pack more coir fiber into the disc, giving the expanded cell more root-development volume than a standard pellet at a similar footprint, which supports bigger plants before they need to move up to a container. That extra volume can mean fewer transplant stages before a seedling reaches its final container.

How do I prepare the pellets before sowing?

Hydrate the compressed discs with warm water until fully expanded into ready-to-use growing cells, then sow seeds directly into the top of each pellet. Warm water speeds expansion compared to cold water.

Do I need to remove the mesh netting before transplanting?

No, the netting breaks down naturally in soil after transplanting, so the whole pellet goes into the ground or a larger container without disturbing the roots. Removing it beforehand risks damaging the root ball.

How many pellets come in this refill pack?

The pack includes 50 pellets, sized to restock a PlantBest greenhouse system for one or more additional propagation cycles. That's enough for a full round of seed starting or cutting propagation.
