Unwrap the coir brick and place in one end of your mixing box.
Put something under the other end of the box so it is angled down towards the brick
Fill Jug with 2.5 - 3 litres warm tap water.
Slowly pour the water over the brick.
Rotate the brick and pour equal amounts over each side.
Wait until the water is absorbed and the brick has expanded.
Use the scoop to break up the brick. Work from each side and the moistened coir will fall way.
The core of the brick may still be dry and hard. If necessary pour another 500 ml of water over the core and leave to stand for a few minutes.
You only want to add enough water so the coir fluffs up - it should not be soggy.
Using the scoop or your hands, break up any lumps in the coir. If you find any leaves or twigs, remove them.
Slowly pour the bag of perlite over the coir.
Use the scoop or your hands to mix well.
Your Coir + Perlite mix is now ready to use.
To prevent contamination always store your prepared mix with the lid on the box.
