Coconut Coir Growing Medium

Coconut Coir (pronounced coy-er) is a growing medium that holds water amazingly well. It is inexpensive, organic, and feels absolutely WONDERFUL.  It is a phenomenal medium for growing Grass, Greens, and Micro-Greens.

We sell Coconut Coir by the brick (almost identical in size to a building brick).  Each brick makes 2 1/2 gallons (40 cups, or 20 Pints) of wonderful loamy material which can be stored indefinitely in a ziplock bag.  This is AMAZING stuff!  We are in love with Coir! LABEL MAY VARY FROM PHOTO.

Follow the instructions on the brick or watch our video to learn how to reconstitute a brick of Coir. Basically - put the brick in a bowl or bucket that is at least 2.5 gallons - and add warm water. It's Fun!

We are absolutely in love with this stuff!  It is a most exceptional growing medium! Coconut Coir (coy-er) holds water phenomenally well and is wonderfully loamy, gorgeous stuff to work with.   Coir is the fibrous material found between the hard, internal shell and the outer coat of a ripe coconut.   Coir has been used in many ways for over a millennia. It is a 100% renewable resource which is odorless, lovely to handle, and uniform in composition.  Coir stores unused minerals to be released to the plant as and when it requires it.   It promotes strong root growth and plant vigor and has an ideal pH range of 6.0-6.8 - and it contains significant amounts of phosphorous and potassium.  Perhaps best of all Coconut Coir is naturally high in compounds called lignins.  This compound encourages the development of beneficial bacteria while discouraging harmful bacteria.  You are going to love this stuff too!

Coconut Coir is an approved medium for organic crops.  We like to add Earthworm Castings - 25% by volume for nitrogen, which makes Coir about as perfect as possible.   

We sell Coconut Coir by the brick.  Each brick is the size of a building brick (though they do vary in size they all weigh the same and so and produces 2 - 2.5 gallons of medium.  All you do is add 1 gallon to 1.5 gallons of water and mix it up.  It should be the consistency of wet soil medium so add ONE gallon of water first and slowly add up to another half gallon if it is too dry. You'll need a container that holds 3 gallons or more.  Anything will do.  We  will also send you a large ziplock bag to store the moistened medium you don't use right away. We have stored it for 4 months with no issues. One brick of Coconut Coir makes as much as 40 cups!  We use at least 12 cups (6 pints) for an 10 x 20 inch tray of grass, so each brick is enough for 3 full tray crops or  6 half-tray (10 x 10 inch) crops.


GrassGreens, and Micro-Greens - and any other seed you want to grow into an edible plant.

Do not try to re-use Coconut Coir. Just compost it and start fresh with your next crop.
