Understanding Coco Coir Bricks and Their Benefits
Coco coir brick is in compressed form, when being rehydrated with water, it expands to 5-7 times its original volume. Therefore, for a small backyard garden, planting just 3-5 bricks weighing 5kg each is enough.
Coco coir bricks have excellent water retention properties, as well as good drainage and aeration, making them an excellent choice for soilless gardening. It also has a neutral pH and does not alter the pH over time and is also resistant to pests and diseases and can be reused multiple times before needing to be replaced.

How to Use Coconut Coir Bricks in 4 Easy Steps
Step 1: Placing the Coco Coir Brick in a Large Container
Put the coco coir brick in a large container. Coco coir will expand 5-7 times its original size, so estimate carefully and choose an appropriate container. Based on the cultivation scale, take a sufficient amount of coco coir brick, without leaving any excess or wastage.
Step 2: Rehydrating the Coco Coir Brick by Adding Water
Please refer to the ratios mentioned above and add an appropriate amount of water to the soaked coco coir brick. Note that the water should cover the coco coir brick, and warm water is recommended to increase the success rate of the water replenishment process. Soak the coco coir brick in water for about 15-30 minutes (depending on which size) to let it expand and absorb water, increasing its moisture content.
Step 3: Breaking and Loosening Up the Coconut Coir Brick
Use your hands or a tool to break the brick into small pieces, this will help to speed up the expansion process. Add water and continue soaking it a little more time . Add just enough water so that the mixture is not too loose, as the coco coir will become overly wet and difficult to use.
Step 4: Using and Properly Storing Excess Coco Coir
After rechecking the technical specifications, coco coir can now be used for cultivation. Growers can mix it with other substrates or use it for soil improvement.
If the coco coir is not used immediately or there is an excess, it should be stored in an airtight container and kept away from damp places. This will help to prevent the coco coir from drying out or being contaminated by bacteria.
Rehydrating Coco Coir Bricks
Came in dried form, coco coir bricks need to be rehydrated before use. Rehydrating coco coir bricks involves soaking them in water for a period of time to allow them to absorb enough water and expand fully.
Since coco coir expands significantly when soaked, growers should consider the amount of coco coir to be soaked and the size of the container. It is important to use an adequate amount of coir and a large enough container to accommodate the expanded coco coir.
After soaking the coco coir, remove it from the water and let it drain. Then, check the pH, moisture content, and other indicators to ensure that the coco coir is ready to be used for planting.
Step-by-Step Process: Rehydrating Coco Coir Bricks
Rehydrating coco coir is a simple process that can be done in a few easy steps:
- Choose a container large enough to hold the coco coir brick.
- Place the coco coir brick in the container and add water. The amount of water needed will depend on the size of the coco coir brick. Generally, the coir should be submerged in water, and warm water is recommended for best results.
- Wait for the coco coir brick to absorb the water and expand. This process can take about 15-30 minutes, and the expansion time may vary for different brands of coco coir brick, so be sure to read the instructions.
- Break the coco coir brick into small pieces with your hands for easier and quicker expansion, then fluff them up to achieve a perfect soil-like texture.
- Once the coco coir brick reaches the full expansion, drain off any excess water. This can be done by transferring the coco coir to a sieve and gently pressing down to remove the excess water.
- Check the moisture levels again, especially the humidity, to ensure it won’t harm the plants.
The coco coir is now ready to use. You can add it to your soil mixture, use it as a standalone growing medium, or mix it with other soil amendments for a customized blend.
Ensuring Proper Watering for Optimal Expansion
The amount of water added must saturate the coco coir bricks. Typically, one 650g coco coir brick is soaked in a 5-gallon container with 4 liters of water. Alternatively, a 450g coco coir brick would be suitable for 3 liters of water. However, the amount of water required for hydrating the coco coir brick may vary depending on the weight and each brand. It is important to read the instructions carefully before use or contact the supplier directly for the most accurate guidance.
Coco coir expands significantly, so it is crucial to carefully consider the amount of coco coir bricks to soak and add an appropriate amount of water to avoid the coco coir becoming excessively dry or overly wet.
Applications of Coco Coir Bricks
After being rehydrated, coco coir brick has the same functions as regular coco coir. Some notable points include:
- Coco coir is lightweight and easy to transport, making it suitable for container gardening.
- It provides a clean and suitable environment for a variety of indoor plants, making it easy for growers to plant them indoors.
- Rehydrated coco coir brick is widely used in hydroponic farming due to its advantages such as good water retention and nutrient retention, neutral pH, good aeration, and water drainage.
- Coco coir can be used as a soil amendment to improve soil structure, increase water drainage, and enhance the absorption of necessary nutrients.
- It can also be used as a seed germination medium, providing a sterile and nutrient-rich environment for germination and promoting good air circulation around the roots.
Coco coir has various other applications, but it needs to be soaked before use, and growers should carefully consider factors that may affect their plants and adjust accordingly.
Hydroponic Growing with Coco Coir Bricks
Coco coir has become an ideal choice for hydroponic growers due to its ability to absorb and retain water, while also having good water drainage and aeration.
Its structure and lightweight texture, similar to cotton, make it a material that provides ample space for healthy root development and ensures optimal nutrient absorption. Additionally, coco coir has a neutral pH and is free from harmful microorganisms, allowing plants to grow safely and efficiently.
Container Gardening and Organic Growing with Coco Coir Bricks
Coco coir brick has good water drainage ability, so when planted in containers, it helps prevent root rot or waterlogging. The structure of coco coir also allows for better aeration into the roots, enabling the plants to absorb the necessary amount of oxygen.
Growers can also mix with perlite to enhance the water drainage capability of the substrate. Alternatively, they can provide nutrient solutions because coco coir brick has low nutrient content, so it’s important to supplement the necessary nutrients for the plants.
Coco coir brick is also sterile, offering resistance to diseases and pests in plants, and creating a favorable environment for plant growth.
Utilizing Coco Coir Bricks for Composting
Thanks to prominent features such as excellent water retention and nutrient content, a structure with desirable aeration, and good water drainage, coco coir has become an excellent environment for worm cultivation.
Coco coir bricks after being dehydrated can be used for breeding earthworms or composting worm castings. Farmers can choose to use coco coir as is for composting or enhance it by adding organic waste such as leaves to achieve better results.
Frequently Asked Questions about Coconut Coir Bricks Usage
Understanding the Nature of Coconut Coir Bricks?
Coco coir brick has the compressed form, so it needs to be rehydrated with water before use. Coco coir bricks come in various sizes namely 650g and 5kg.
Suitability of Coco Coir for Seedlings?
Coco coir is a benign growing medium because it has antibacterial and pest-resistant properties. In addition, the unique structure of coco coir provides optimal conditions for root development. Therefore, coco coir is highly suitable for seed germination.
