PlantBest™ Coconut Coir Pellet Refill — 20pcs — 42mm

Peat-Free Expandable Growing Discs for Standard Pellet Trays

Peat-based seed pellets need lime adjustment to correct their naturally acidic pH, an extra step that coir doesn't require in most cases. PlantBest's Coconut Coir Pellet Refill compresses coir fiber into 42mm discs, each held in fine netting, that expand into full-sized growing pellets once hydrated — a peat-free alternative sized to fit standard 42mm pellet trays and systems.

The 20-piece pack suits home growers who use coir pellets regularly through a season, restocking a standard tray without buying a larger bulk quantity than needed.

Key Features & Benefits

• 20-piece refill pack, 42mm — standard sizing compatible with seed-starting systems and trays designed for peat-style pellets.
• Near-neutral pH — coir requires less lime adjustment than peat for most crops, simplifying pellet prep.
• Renewable coconut coir source — made from coconut husk byproduct rather than harvested peat bog material.
• Fine netting holds pellet shape — keeps the expanded coir in a defined disc for easy handling, tray placement, and transplanting.

Who Should Use This

Home growers who use 42mm pellet-style seed-starting systems and want a peat-free refill for regular seasonal use will get the most from this 20-piece 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

How do these coir pellets compare to peat pellets?

Coir has a naturally near-neutral pH, so it needs less lime adjustment than peat for most crops, and it re-wets more easily once dry. It's also derived from a coconut-husk byproduct rather than harvested peat bog material.

How do I prepare the pellets before sowing?

Hydrate the compressed discs with water until they fully expand into individual pellets, then sow seeds directly into the top of each expanded pellet. Full expansion usually takes just a few minutes in room-temperature water.

Will these fit my existing 42mm pellet tray?

Yes, these pellets are sized to the standard 42mm format used across most seed-starting systems and trays built for peat-style pellets. Confirm your tray's cell diameter before ordering if you're unsure of the size.

Do I need to remove the netting before transplanting?

No, the fine netting holds the pellet's shape and can go into the ground or a larger container along with the rest of the pellet without disturbing the root ball. The netting breaks down over time once buried.
