PlantBest Coconut Coir Refill Pellets - 36pcs - 35mm

35mm Coconut Coir Pellet Refills for PlantBest Greenhouse Kits, 36pcs

Restocking pellets between plantings shouldn't require buying a whole new tray and dome. PlantBest sells its 35mm coconut coir pellets separately from the complete kit, so growers who already own a PlantBest tray can restock exactly the pellet count they need.

This 36-count pack restocks a PlantBest kit for home gardeners running a smaller, more occasional round of seed starting or cutting propagation.

Key Features & Benefits

• Loose 35mm coconut coir pellets — no tray or dome included, sized to restock a PlantBest kit.
• Dried and compressed in fine-mesh netting — expands with warm water into a ready-to-use growing cell.
• Renewable coconut coir material — a peat-free alternative with excellent moisture retention and aeration.
• Available in multiple refill counts — match order size to how often you start new seedling batches.

Who Should Use This

This fits growers who already own a PlantBest 35mm tray-and-dome kit and need to restock pellets for another round of seed starting or cutting propagation.

About PlantBest

PlantBest sells its coconut coir pellets both as complete kits and as standalone refills, letting growers reuse an existing tray and dome instead of buying a new kit every season. The company, founded by Thijs Millenaar, sources its coir from processing facilities in India, Sri Lanka, and Vietnam.

Frequently Asked Questions

How do I refill my PlantBest greenhouse kit with these pellets

Drop the loose pellets into your existing tray, add warm water, and let them expand fully before sowing seeds into the top of each one. The process matches pellets that ship inside a complete PlantBest kit.

When should I order a refill instead of a new kit

A refill pack is the better choice as long as your existing tray and dome are still intact and only the pellets have run out. Replacing the whole kit only becomes worthwhile once the tray itself cracks or you need a second greenhouse running alongside it.

Can I use these pellets for rooting cuttings as well as seeds

Yes, the moisture retention and aeration that support seed germination also work for rooting cuttings. The same pellets serve either purpose without any special preparation.

What's the difference between the 72-piece and 36-piece refill pack

Both use the same 35mm pellet size, just scaled to a smaller or larger batch. The choice comes down to how many seedlings or cuttings you're starting at once.
