Our dehydrated coco coir was developed for superior mycelial growth, providing optimal pH, moisture retention, even gas exchange, and key trace minerals to your mushroom grow. The first coco coir researched and selected specifically for its mushroom cultivation qualities, Myco Coco can be used as both a casing layer and substrate additive. It is also a world-class substrate for growing plants indoors or outdoors.

Triple-washed and buffered to adjust pH and nutrient levels, Myco Coco creates the ideal air-to-water ratio, making it ideal for cultivating gourmet and medicinal mushrooms. RHP certified to guarantee the highest substrate standards in the industry, it is naturally free of pests and weed seeds. Myco Coco is made from coconut husks, is biodegradable, and is a 100% renewable resource. It also contains traces of Magnesium and Calcium that contribute to the overall growth of mushrooms.

Coco coir is widely used in mushroom cultivation due to its microbial resistance, ability to retain moisture, and nutrient composition. It is primarily used as a casing layer in monotubs or as a substrate additive. However, it can also be used in garden beds as an alternative to peat moss.

Makes ~1 gallon (3-4 Liters) of coco coir once rehydrated

How to use:

  • As a casing layer: Coco coir should only be added to fully-colonized substrate covered in mycelium with well-developed primordia and/or pins beginning to form. Only a thin layer of coco coir (1/4 to 1/2 inch) is necessary.
  • In bulk substrate: After rehydration (see instructions below) combine coco coir with other ingredients to your bulk recipe at the desired quantity. Pasteurize or sterilize after combination.

IMPORTANT: Dehydrated coco coir must be rehydrated and pasteurized before use. (Scroll down for complete instructions.)

Rehydration & pasteurization

TO REHYDRATE FOR USE:

Please note: Once hydrated, Myco Coco should be used the same day. One brick of Myco Coco is enough to case two Boomr Bins or similarly-sized monotubs.

1. Bring two quarts or liters of water to a boil. Turn off the heat source.

2. Place your brick in a clean, heat-safe bowl or bucket. Pour the hot water onto the coir and watch it expand! Wait for the temperature to drop enough that it is safe to touch. 

3. Using clean or gloved hands, thoroughly mix the coir and water until no dry coir remains. Transfer half of the hydrated coir to the top of the fully colonized substrate as a casing layer.

4. Check on the casing every few days to see if additional hydration is needed. Use a spray bottle of previously boiled or distilled water to rehydrate.

WARNING: Burn Hazard

Can cause skin burns if coco coir does not cool water sufficiently, handle with extreme caution.

Works well and it's fun to watch expand!

A little bit goes a long way. Keep your coco layer pretty thin.

Great value CC

I have used this block CC and its a great product. I might prefer the loose but I have this on hand in a pinch.

Thanks for the review, Jackie! The team is here if anything comes up.

Works well

Worked well but hard to break apart. I used to mix with rye berries and inoculated with liquid culture. If you're using the whole block at once you can just hydrate it but its tough breaking off pieces for multiple use. Still worked great

Thanks for the honest review, Dan! If you need help with anything, please reach out.
