FAQ
Coconut substrate consists of three main fractions: coconut peat (fine), coconut fibers (long), and coconut chips (large particles). The structure affects water retention, drainage, and aeration. Porosity and air permeability are key, especially in greenhouse cultivation. A mix of 60% chips and 40% peat provides good aeration and medium water retention—ideal for tomatoes and cucumbers.
With proper use, coconut substrate maintains its structure and properties for up to 1 year. After that, it may begin to degrade, losing aeration capacity.
It may contain natural salts if not washed or buffered. Unprocessed substrate can have high EC due to sodium and potassium. Our substrate is thoroughly washed and often calcium-buffered, with EC levels typically below 0.5–0.6 mS/cm. It contains no pathogens, heavy metals, or foreign impurities.
pH ranges from 5.5 to 6.5—optimal for most crops including tomatoes, cucumbers, and strawberries.
The mix is 60% coconut chips and 40% coconut peat. No other organic or inorganic additives are present.

All necessary certificates are provided to customers.
Coconut substrate decomposes slowly due to high lignin and cellulose. It retains structure for years. Coir is fermented for 14–18 months before use to eliminate pathogens and improve quality.
3 to 6 weeks depending on region.
6 to 8 weeks on average.
One 40-foot container or 12,000 grow bags (100×15×12 cm).
Determined individually based on volume and delivery terms.
Stored in dry, ventilated warehouses at +15°C to +35°C, humidity ≤75%. Protected packaging and palletized storage prevent contamination.
Yes, if your order meets the minimum volume, you can request a free sample.
Depends on order volume, substrate composition, and delivery terms.
Additional discounts for orders over 30 containers.
First three orders require 50% prepayment; remaining 50% upon readiness for shipment.
Promotes healthy growth and high yield. Reduces water usage by up to 40%, improves nutrient absorption, and optimizes root aeration. Field trials show up to 20% yield increase compared to traditional substrates.
Ideal for tomatoes, strawberries, peppers, cucumbers, and more in open or protected soil.
Moisture should be “field capacity”—a few drops when squeezed. Too wet if water flows; too dry if it crumbles.
Vegetative stage: ~65% after watering, ~45% before next watering
Flowering: 45–25% during day, lower at night
Mushroom cultivation: 50–60% optimal

The table below presents key technical characteristics and recommended parameters for coconut substrate, designed for greenhouse cultivation of tomatoes, cucumbers, berries, and other crops.
Structure (fractions) | 40–60% peat, 20–40% chips, 10–20% fiber | Adjusted based on crop (tomatoes, berries, flowers) |
Bag size | 100×15×12 cm, volume 18 liters | Standard for greenhouse cultivation |
Weight (dry) | 2.2 kg ± 5% | Important for logistics and storage |
pH | 5.5 – 6.5 | Optimal for nutrient uptake |
EC (electrical conductivity) | < 0.5 – 0.8 mS/cm | Safe salt level after washing |
Na⁺ and K⁺ content | Na⁺ < 0.03%, K⁺ < 1% | Standard for washed and buffered substrate |
Water Holding Capacity (WHC) | ≥ 700% | Good water retention ability |
Total Porosity | ≥ 85% | Ensures aeration and drainage |
Air-Filled Porosity | 10–20% | Crucial for root respiration |
Organic matter | > 90% | Indicates purity of coconut material |
Dust content | < 10% | High dust content impairs drainage |
Pathogens and weed seeds | Absent | Confirmed by thermal treatment |
