Organic Coconut Coir Brick for Growing Mushrooms

It’s a compressed brick made of coconut husk, but don’t tell the government or they’ll start trying to solve the housing crisis by using it to make tower blocks or something (haha just kidding they would never try to solve the housing crisis).

Simply add water and watch it breach the small bucket you thought would contain it! This thing wants out, and just like a billionaire in a homemade submarine, when you expose it to water a swift structural change occurs (although in this case it gets a lot bigger, not a lot smaller)!

When you’re buying your coconut coir (or just coco coir to his friends) it’s important to get the right type for growing mushrooms. Some of the blocks are specifically for plants, and they add trichoderma to it because plants love it. Trichoderma is the home mushroom cultivator’s number one enemy because it is fucking everywhere (apart from in front of our lovely flow units) and it will wreck your grows like nobody’s business if you’re not careful. This coir doesn’t have any of that added to it, so it’s great for growing your own dinner on. 

Properly hydrated, the smaller size will give you almost 10 litres of substrate, and the larger size will expand to 75 litres of substrate which is a marvel of modern science.

✅ Approx. 650g per brick or 5kg for the larger one, but this varies as some are more compact that others.
✅ Doesn’t need to be sterilised, but can be pasteurised (see below)
✅ Increases LOADS when you add water
✅ You could throw this into an Olympic-sized swimming pool and get banned for life for being weird
✅ Stores for millennia if kept dry
✅ Organic like as much as our stuff as possible
✅ Pronounced “Koy-er” not “Kwaar”, it’s not French

Storage:

• Literally anywhere you like as long as it isn’t moist 

How to use:

• Friend of MycoPunks, Orangutan Trading Co, actually wrote a blog post about this very topic about two years ago where he’s gone into detail about how he used to pasteurise it when he was living abroad, we asked permission to share it, he said “yes”, so here it is: how to use coco coir!
• You can also use it as a casing layer if you like, just hydrate it like in Orangutan’s guide and then apply about ½ inch or a bit less over the surface of your fully colonised substrate. Don’t do it before that or it’s just part of your substrate.

If you want to add some vermiculite and gypsum to it at the right ratios, we actually sell a complete kit with all of that included just over here
