Coconut Coir

(12 customer reviews)

£5.00 (incl. VAT)

Coconut coir is made from the husks of coconuts which are then shredded and compressed into coir ‘bricks’. With high water retention and amazing resistance to contamination, they are a favourite choice of many home mushroom cultivators as a bulk substrate.

No need for steralisation and can be pasteurised using in the classic ‘bucket-tek’ method by simply adding boiling water and leaving until cool.

  • Suitable for small to large scale home mushroom cultivators
  • Indefinite lifespan if stored dry
  • Perfect for the beginner
  • Contamination resistance
  • Can be used as a casing

Our coir bricks have a lower salt concentration than others found on the market which we’ve seen helps with increased colonisation times with bigger flushes and fruits. Often used in conjunction with vermiculite to provide a light and fluffy substrate with good water retention capacities.

1 brick = Approx. 550g-650g

These guys are great and definitely worth the coin! I don't get grow bags from anywhere else now but have found these have the perfect ratio of contents and have never been contaminated so it is clear its very sterile.

  1. Siltone

    Hydrate in wheelbarrow and cover. I'm just getting into mushroom cultivation but used to use this stuff to help with my heavy clay soil in garden. Multiple uses. Happy customer

  2. Paula Lucas

    Can be a bit dusty if breaking chunks off but to be expected. Fast delivery. No problems.

  3. Natalie

    Highly compressed brick of coir. Seems to do the job. I'll update after my first harvest!

  4. Lorkin

    Cheap and good quality

  5. R Harvey

    Creates an ideal substrate for cubes, can be composted after. It's the outer shell of coconuts, very contamination resistant. I normally hydrate then mix with a bit of Gypsum for some added nutes. Been using this stuff for years as you can do away with expensive lab equipment. Buket tek is best, good yields. Thanks (use boiling water to hydrate then allow to cool, cold water doesn't work as well)
