How to Expand the Coco Grow + Coir Block

  1. Simply place the compressed Coco Coir - Coco Grow+ brick into a container.
  2. Mix in 4-5L of warm water (cold is acceptable, but may require extra waiting time).
  3. Allow it to rest until the water is fully soaked, approximately 10 minutes.
  4. Aerate the compost to ensure proper air circulation, breaking up any clumps thoroughly.
  5. You’re ready to get seeding and planting up!

Tips to speed up expansion:

  • Carefully pour the water onto the block's center, allowing the water to absorb from the centre outward.
  • Ensure that the block is entirely submerged in water, instead of just sitting on the surface.
