Every brick is triple washed, low EC, pH neutral and OMRI Listed, and it is compressed tight for storage. Each one opens up to more than 20 gallons when hydrated, so this order adds up to more than 8,800 gallons of expanded coir.

Why growers buy coir by the pallet

Lowest cost per brick

The more you buy, the less each brick costs.

Triple washed, low EC

Excess salts are rinsed out, so you start from a clean base for mushroom substrate.

Holds water, keeps air

Stays moist without packing down or waterlogging, which supports even colonization.

How to hydrate a brick

1Use a big container

A 5kg brick grows to more than 20 gallons, so start with a large tub, bin or mixer.

2Add hot water

Pour it over the brick and let it soak in and loosen the fibers.

3Break it up

Fluff the coir by hand as it expands until there are no dry clumps.

4Mix and prepare

Blend with vermiculite and gypsum for CVG, then pasteurize as your recipe calls for.
