1. What Is Coco Peat?

Coco peat is a natural growing medium made from coconut husk pith. It is valued for its high water-holding capacity, excellent aeration, and sustainable origin.

At Vinatap, coco peat is processed through washing, drying, and sieving to ensure low EC and consistent quality. For growers who need ready-to-use formats, Coco Peat 50L is one of the most convenient options.

For strict greenhouse requirements, many buyers choose Low EC Coco Peat as their base substrate.

2. What Is Perlite?

Perlite is a volcanic mineral expanded by high heat. It is lightweight, sterile, and commonly used to improve drainage and aeration in potting mixes.

Unlike coco peat, perlite does not retain nutrients or water for long periods. Its primary function is to create air space around plant roots.

3. Coco Peat vs Perlite – Key Differences

4. Which Crops Benefit Most from Coco Peat?

Coco peat is especially suitable for:

• Vegetables (tomatoes, cucumbers, peppers)
• Leafy greens
• Strawberries and berries
• Ornamental plants and flowers

Its ability to retain moisture while remaining well-aerated makes it ideal for greenhouse environments with controlled irrigation.

5. When to Mix Coco Peat and Perlite

In many professional greenhouses, coco peat and perlite are used together to create a balanced growing medium.

A common mix ratio is:

• 70% coco peat + 30% perlite – for vegetables
• 50% coco peat + 50% perlite – for seedlings and cuttings

This combination provides both water retention and enhanced drainage, optimizing root development.

6. FAQ – Coco Peat vs Perlite

Is coco peat better than perlite?

Coco peat is better for water and nutrient retention, while perlite excels at aeration. The best choice depends on crop type and irrigation method.

Can coco peat replace perlite completely?

For many crops, yes. However, adding perlite can further improve drainage in certain systems.

Is coco peat more sustainable than perlite?
