Why Coco Coir is Perfect for Growing Microgreens
A Clean, Sustainable Growing Medium Trusted by Professionals
At Skye Mountain Microgreens, we believe growing your own food should be as clean, sustainable, and simple as possible. That’s why every one of our Water Once punnets is filled with 100% organic, sterile coco coir—a naturally clean, soil-free medium that delivers professional results for home growers and chefs alike.
But what exactly is coco coir—and why is it the superior choice for microgreens?
Well, coco coir (pronounced coy-er) is a fibrous material extracted from the husk of coconuts. Once a byproduct of the coconut industry, it’s now a renewable, biodegradable resource helping people grow food more sustainably.

1. Sterile & Soil-Free for Food Safety
Our coco coir is naturally sterile, containing no soil-borne pathogens, bacteria, or chemical additives. This ensures your microgreens grow in a clean, safe environment, making it a trusted choice for culinary professionals and food businesses.
2. Excellent Water Retention
Coco coir holds just the right amount of moisture, keeping your microgreens hydrated with minimal effort. That’s why our kits need just one watering—no guessing, no overwatering.
3. Resistant to Mould & Pests
Unlike traditional soil, coir naturally discourages mould and pest growth. It helps keep your crop clean, healthy, and odour-free—perfect for indoor use or professional kitchens.
4. Lightweight & Easy to Handle
No heavy soil, no mess. Coir is light, fluffy, and ideal for small-space growing systems—whether on a countertop, windowsill, or commercial prep bench.
5. pH Balanced for Optimal Growth
Coco coir typically has a pH between 5.5–6.5, making it ideal for microgreens. This balanced profile promotes vibrant growth and maximum nutrient uptake.
