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.

Understanding Coco Coir Bricks and Their Benefits

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.

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:

  1. Choose a container large enough to hold the coco coir brick.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Check the moisture levels again, especially the humidity, to ensure it won’t harm the plants.

Ensuring Proper Watering for Optimal Expansion

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.

Applications of Coco Coir Bricks

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.
