Coco bricks, also known as coconut coir bricks or coco peat bricks, are a type of growing medium made from the fibrous husks of coconuts. These bricks are compressed blocks of coconut coir, which is the fibrous material found between the hard, internal shell and the outer coat of a coconut.
Coco bricks are popular among gardeners and horticulturists because they are organic, renewable, and environmentally friendly. They have excellent water retention properties while still providing good aeration to plant roots. Additionally, they are pH-neutral, which means they won't affect the pH balance of the soil.
To use coco bricks, you typically soak them in water until they expand and fluff up. Once hydrated, they can be used as a soil amendment, seed starting medium, or as a component in potting mixes. They're particularly useful in hydroponic systems and for growing plants in containers. Overall, coco bricks offer a sustainable alternative to peat moss and other traditional growing mediums.
