Coco-Perlite Mix

Q: Why should growers add perlite to their coco mix?

A:

• Improved Aeration: Coco coir can tend to become compacted over time, which restricts the flow of air to the roots of plants. Adding perlite helps maintain good aeration in the growing medium by creating air pockets. This ensures that plant roots receive an adequate oxygen supply, crucial for healthy root development.

• Enhanced Drainage: Perlite is a lightweight and porous material, so when mixed with coco coir, it improves the drainage properties of the growing medium. This prevents water from accumulating at the bottom of pots or containers, reducing the risk of root rot and other moisture-related problems.

• Reduced Compaction: Perlite's structure helps prevent coco coir from compacting too tightly, ensuring that the growing medium remains loose and friable. This makes it easier for plant roots to penetrate and grow through the medium.

• Improved Water Retention: While perlite primarily improves drainage, it also helps the growing medium retain some moisture. This balance is beneficial because it allows for a consistent level of moisture around the roots without causing waterlogged conditions.

• pH Buffering: Perlite is pH-neutral, meaning it doesn't significantly affect the pH of the growing medium. This is important because coco coir tends to be slightly acidic, and the addition of perlite helps stabilize the pH, providing a more suitable environment for a wider range of plants.

Q: What's the ideal coco and perlite mix ratio?

A: The preferred blend for premium hydroponic grade use is a 70/30 ratio of Coco Coir (also known as coco peat) to Perlite.
