Coco - Section 1: Using as a medium


When it comes to growing plants, the choice of a suitable growing medium plays a crucial role in their overall health and development. Coco coir, derived from the fibrous husks of coconuts, has gained popularity among growers as an exceptional alternative to traditional soil-based methods. In this blog post, we will delve into the world of coco coir and explore its advantages, different types, and how to prepare it for planting. Whether you're planning to cultivate cannabis or other plants, understanding coco coir as a growing medium is essential for successful and thriving gardens.


1. What is Coco Coir?

Coco coir is a natural, renewable, and environmentally friendly growing medium made from the fibrous husks surrounding coconuts. It is a byproduct of the coconut industry and has gained recognition as an excellent alternative to traditional soil-based mediums. Coco coir is available in different forms, including blocks, bricks, or loose fibers, and is known for its excellent water retention and aeration properties.

2. Advantages of Coco Coir:

  • Excellent Water Retention: Coco coir has an impressive water holding capacity, allowing plants to access moisture when needed while also promoting adequate drainage. This characteristic helps prevent overwatering and root rot, providing plants with a balanced moisture level
  • Enhanced Aeration: The fibrous structure of coco coir creates air pockets, ensuring proper oxygenation of the root zone. This promotes healthy root growth, nutrient uptake, and overall plant vigor.
  • pH Neutral and Buffering: Coco coir has a neutral pH, which means it is not overly acidic or alkaline. Additionally, it possesses natural buffering properties, making it more forgiving for growers when adjusting pH levels during nutrient feeding.
  • Excellent Nutrient Retention: Coco coir has a high cation exchange capacity (CEC), which allows it to hold and release nutrients effectively. This enables plants to access essential elements for growth and development.

    3. Different Types of Coco Coir:

    There are three main types of coco coir available on the market:

    • Coco Coir Fiber: This type consists of long, fibrous strands and is commonly used for erosion control or as a component in potting mixes.
    • Coco Coir Peat: Also known as coco peat or coir pith, this type is derived from the finer particles of coco coir. It has excellent water retention properties and is often used as a primary component in soilless growing mixes.
    • Coco Coir Chips: These are larger coconut husk pieces, providing enhanced aeration and drainage. Coco coir chips are commonly used in hydroponic systems or as a component in potting mixes.

          4. Preparing Coco Coir for Planting:

          • Before using coco coir as a growing medium, it is essential to prepare it properly
          • If using coco coir blocks or bricks, they need to be rehydrated before use. Soak the blocks/bricks in water until they expand and break apart. Remove any excess salt by rinsing with freshwater
          • Coco coir may contain salts or residual nutrients. To ensure a clean and balanced medium, flush it with water until the runoff shows no signs of excess salts or nutrients
          • Buffering: To stabilize the pH of coco coir, it is recommended to pre-buffer it with a pH-neutral solution. This helps prevent pH fluctuations during the early stages of plant growth


            Coco coir offers numerous advantages as a growing medium, making it a popular choice among growers for cultivating cannabis and other plants. Its water retention, aeration properties, pH neutrality, and nutrient retention capabilities make it an excellent option for both beginners and experienced growers. By understanding the basics of coco coir and how to prepare it for planting, you can create an optimal growing environment that promotes healthy plant growth and maximizes yields. So, get your coco coir ready and embark on an exciting journey of successful plant cultivation!
