Coco Coir Brick

While expansion rates can vary slightly based on water temperature and absorption, a single brick typically expands to roughly 8 to 10 times its compressed volume. You should expect one brick to fill a standard medium-sized pot.

Coco coir is naturally inert, meaning it doesn't contain significant nutrients on its own. While it provides excellent structure for roots, you will need to mix in your own fertilizer or liquid plant food to support long-term growth.

You can use it either way. It works well as a standalone medium for hydroponics or specific container plants, but many gardeners prefer mixing it with traditional potting soil or perlite to improve drainage and aeration.

Using hot water helps break down the compressed fibers faster and more thoroughly than cold water. It also helps sanitize the medium slightly and ensures the brick expands to its full, fluffy potential.
