This coco coir fiber grow mat is designed to fit 10″ x 20″ grow trays, making it ideal for microgreens, herbs, and salad greens. The natural coconut coir liner retains moisture to support healthier greens and seedlings. It can serve as a seed starter liner, hanging basket liner, or planter sheet with simple trimming.

This larger pack offers the same 10″ x 20″ mats but in a 20-count bundle, ideal for commercial microgreen operations or households with multiple trays. It delivers the same moisture retention and aeration benefits as the 10-pack, helping ensure consistent germination and leaf formation.

Remiawy Coco Liner Roll, 16 x 120 Inch
The Remiawy liner roll is a long, continuous sheet of natural coconut fiber designed as a liner for planters, hanging baskets, and window boxes. It provides moisture retention, breathability, and soil protection for plant roots. Best for gardeners who need a flexible, economical liner that can be cut to fit unusual container shapes. Limitation: rolling width is fixed, so very narrow containers may require extra trimming and waste.
MIOHNAN Natural Coco Coir Fiber Liner Roll Sheet 16×48 Inch
Designed as a liner roll sheet, this MIOHNAN product is 16″ wide and 48″ long, offering a flexible size for various planters and baskets.

Caution: ensure proper soaking and trimming for an exact fit to prevent gaps that could hinder moisture distribution.
Coco Bliss (10lbs) Organic Coco Coir — For Soils and Potting Mixes
While marketed primarily as a soil amendment and potting mix component, this pre-rinsed and pre-screened coconut coir brick is a strong option for seed starting and seedling trays when expanded with water. It’s useful for growers who want a high-moisture-retention base that can be mixed with other substrates. Best for those who want to customize potting media rather than rely solely on pre-cut liners. Limitation: not a ready-made liner; requires preparation before use in microgreen trays.
SDLDEER 12 PCS Coco Coir Bricks
SDLDEER offers 12 compressed coco coir bricks that expand when soaked, yielding several gallons of growing substrate. This option is ideal for compact storage and for growers who want to expand a grow medium on demand. Best for seed starting, herb growing, and transitioning from brick media to container trays. Caution: needs time to fully expand and may require additional aeration to prevent compaction in dense plantings.
Buying Guide: Key Considerations For Microgreen Liners
Choose liner material based on tray size, moisture needs, and ease of use. Coco coir liners improve water retention and airflow compared with peat-based substrates, but they require proper sizing and cutting for a snug fit. Consider the following:
- Tray compatibility: Standard microgreen trays are often 10″ x 20″ or 9″ x 9″. Match liner size to your trays to prevent dry edges or overwatering.
- Moisture management: Coir maintains moisture well, supporting even germination and sprout formation. If your environment is very dry, thicker liners or multiple layers may help.
- Airflow and drainage: Coir fibers enable aeration that reduces root rot risk. Ensure liners are not so dense they block drainage paths.
- Ease of use: Pre-cut mats save time; liner rolls require cutting to size but offer flexible fits for non-standard containers.
- Storage and handling: Bricks and rolls ship compactly but require soaking and expansion. Plan for prep time in your workflow.
- Caution and limits: Some products are sized for specific tray formats; always verify dimensions and fit before purchase to minimize waste.
