Empty two bags into a good size wheelbarrow and add 8-10 litres of water per bag (dependent on weather).
Once the pellets have been sufficiently watered, leave the wheel barrow for a minimum 15 minutes to allow the pellets to expand.
Turn the pellets over with a fork ensuring that all the pellets come into contact with the water and leave for a minimum 15 minutes to allow the pellets to expand.
Empty the contents of the wheelbarrow onto the stable floor, and repeat the previous stages until you have the required amount to make a comfortable bed. More water can be added if required.
Finally rake the bedding into a position that suits your horse.
Multiple wheelbarrows makes this process much quicker and easier and if you have a large wheelbarrow you may be able to do more than two bags at once.
