Description
Coco Coir Growing Medium for Microgreens
Coco coir, also sold as coconut coir, is coconut husk fibre, the only growing medium in our range that is not a mat. It arrives as a compressed brick and becomes loose substrate in your tray, so you decide how deep the layer is. The 650 g brick soaked in approximately 3 litres of water expands into about 7 litres of ready medium. The 550 g brick needs approximately 2.5 litres of water and produces about 6 litres of growing medium.
What you get
- Compressed brick in two sizes: 550 g produces about 6 litres of growing medium with approximately 2.5 litres of water; 650 g produces about 7 litres with approximately 3 litres of water.
- 100% coconut fibre, biodegradable and compostable together with the crop residue.
- pH neutral, so it does not shift the pH of your nutrient solution.
- Holds up to ten times its own weight in water, which keeps seeds moist through germination on low watering. Suitable for hydroponic systems and tray growing alike.
- Clean to store and handle: dry and light until you need it, unlike bagged soil.
Pack formats
Coco coir comes as a single 650 g brick and as a 10-brick pack for larger operations, and in a 550 g brick with its own 10-pack. Pick the 10-packs when you run several trays a week and want to buy the season in one delivery.
How to use coco coir for microgreens
- Soak the 550 g brick in approximately 2.5 litres of water, or the 650 g brick in approximately 3 litres, and let it expand. Warm water works fastest.
- Spread a 1-2 cm layer across the tray and level it. Deeper for crops you want to root further, thinner for fast leafy cycles.
- Sow, cover for blackout, then water lightly. Coir holds moisture, so it needs less watering than most substrates.
- After harvest, compost the used medium together with the roots.
One thing to plan for: coir carries no nutrients
Coconut fibre is an inert medium. It holds water and air and gives roots something to grip, but it feeds nothing. For crops longer than a few days, and for any commercial cycle, add a nutrient solution, for example MP Seeds Fertilizer for Microgreens. If you prefer a ready-cut sheet, choose a CocoMat made from the same coconut fibre. CocoMat also contains no nutrients, so we recommend using a fertiliser with it too.
Coco coir or a coco mat
Coir gives you control over the depth of the medium and one material for trays of any size. A mat gives you the same thickness everywhere, no levelling and no residue on the bench. Both are coconut coir, pH neutral and biodegradable. See all coconut growing media, or compare the whole range of growing media for microgreens.
Due to the nature of the material and the production process, the delivered product weight may vary by approximately ±10%.
