At cocoX, we believe the future of professional horticulture starts with a truly clean, consistent, and renewable growing medium. That’s why we developed NanoFilter Technology — our proprietary nano-filtration process that removes over 95% of salts from coconut coir substrate, consistently achieving an ultra-low EC value below 0.1 mS/cm in standard testing.
For growers, this number is more than just a spec — it’s a game-changer.
Why Ultra-Low EC Matters So Much
Most commercial coconut coir products arrive with EC levels between 0.5–1.5 mS/cm (and sometimes higher), requiring significant rinsing, buffering, or acid washing before use. Even after treatment, variability between batches can lead to uneven crop performance, nutrient imbalances, or delayed rooting — especially in sensitive crops.
With cocoX’s NanoFilter-treated coir:
- EC starts below 0.1 mS/cm right out of the bag — no pre-rinsing needed
- pH remains naturally stable in the optimal 5.5–6.5 range
- Nutrient programs can begin immediately and precisely, without the risk of early salt buildup or lockout
- Batch-to-batch consistency is dramatically improved, giving nurseries and propagation facilities the predictability they need for high-value production
Ideal for the Most Demanding Crops
This level of cleanliness opens up new possibilities for growers working with salt-sensitive species:
- Blueberries — thrive in low-EC, well-aerated media with minimal cation competition
- Strawberries — benefit from uniform moisture and reduced risk of tip burn or uneven fruit set
- Seedling production — faster, more uniform germination and stronger early root development
- Tissue culture and micropropagation — a near-sterile, ultra-clean starting substrate that reduces contamination risks and media-related variability
How NanoFilter Technology Works (What We Can Share)
Unlike traditional reverse osmosis (RO) systems that can be energy-intensive, slow, and sometimes overly aggressive on the coir’s natural fiber structure, our NanoFilter method uses an advanced nano-scale filtration approach. It selectively targets and removes dissolved salts while preserving the coir’s beneficial physical properties — porosity, water-holding capacity, re-wettability, and natural structure — that make coconut coir such an excellent growing medium in the first place.
The exact process and key innovations behind achieving this sub-0.1 mS/cm level remain a commercial secret for now. What we can say is this: we have already successfully brought this performance to market, and the results from real growers are confirming what our lab data promised.
The Bottom Line for Growers
With NanoFilter Technology, cocoX isn’t just offering another washed coir — we’re delivering a fundamentally cleaner, more reliable, and immediately usable substrate that saves time, reduces water and chemical inputs, and supports higher yields in precision growing systems.
Whether you’re transitioning away from peat, scaling up young-plant production, or looking for a consistent medium for your most valuable crops, CX-01 powered by NanoFilter Technology is designed to meet — and exceed — your expectations.
