How to use:
Choose a large container or bucket with a capacity of at least 10 litres.
Place your coco coir brick in the container and pour over about 4 litres of water.
The brick will absorb the water and expand rapidly. Allow the water to absorb for 30 - 60 minutes before breaking up the coco coir. Add more water if there are any dry clumps.
Rehydrated coco coir can then be stored in a dry location, indoors or outdoors.
If you want to only use a portion of the brick, you can slowly add water to a portion of the brick and scrape off what you need as it expands.
