Coco grow cubes, also known as coconut coir grow cubes, are small blocks made of compressed coconut coir, a fibrous material derived from the outer husk of coconuts. They are often used as a growing medium for plants, especially in hydroponic systems, as they have excellent water retention properties and can provide aeration to the plant roots.
To use coco grow cubes, you typically soak them in water to expand and soften them, and then plant the seeds or seedlings directly into them. The coir will hold onto moisture and nutrients, providing the plants with a suitable environment to grow in. As the plants mature, their roots will grow into the coir, and the cubes will gradually break down over time, providing additional organic matter to the soil.

Coco grow cubes are an eco-friendly alternative to peat moss, which is often used as a growing medium. Coconut coir, on the other hand, is a renewable resource.
