🧪 Why Buffering is Necessary for coco peat?
Raw or even washed coco peat naturally contains high levels of sodium and potassium, which:
- Can displace essential nutrients (like calcium and magnesium) from the plant root zone.
- May lead to nutrient imbalances or toxicity over time.
BUFFERED COCO PEAT
By buffering, you’re essentially pre-treating the coco peat to make it more plant-friendly, especially for sensitive or high-value crops.
🔄 The Buffering Process of coco peat (Simplified)

- Pre-washed coco peat is soaked in a calcium nitrate (Ca(NO₃)₂) or calcium-magnesium solution.
- The calcium ions displace the sodium and potassium ions attached to the coir particles.
- The media is then rinsed to wash out the displaced Na⁺ and K⁺ ions.
✅ Benefits of Buffered Coco Peat

- Better nutrient absorption for plants
- More stable pH and EC (electrical conductivity)
- Reduces risk of salt stress
- Safer for direct planting and hydroponics
📦 Typical Buffered Coco Peat Specs

Here’s what a good buffered coco peat might look like:
- EC: < 0.5 mS/cm (1:1.5 or 1:2 method)
- pH: 5.5–6.5
- Washed and buffered with calcium nitrate
- Moisture: < 15%
- Free from weed seeds and pathogens
- Expanded volume: 70–75L per 5kg block
🧑🌾 When to Use Buffered Coco Peat

- Ideal for hydroponic systems, nursery trays, or high-value crops like lettuce, strawberries, or tomatoes.
- Recommended when customers are mixing their own fertilizers or using automated
