Qualities of Coir
• Easy re-saturated with water
• Stable substrate if composted / high Lignin
• High air-content
• Fibres and/or husk chips further increase airiness
• Water-air-content positive compared to peat
• Mixable with peat
• Organic origin. Recyclable after use
• Perfect alternative for ‘peat-free’ demands
• Full control from husk to end product (end user)
• RHP-approved from the production location onwards
• Experience in all major horticultural areas with a variety of cultures
• Total hydroponic range: Jiffy 7C, Grow Block, Grow Bag
General directives for the use of coir
Coir has a water buffer. Coir acts as a dry medium.
Coir has a loose, airy structure. A better air/water-content improves root development.
An airier substrate means a drier substrate. All this simplifies irrigation.
Some seeds do better with a wetter pellet, while some cuttings do better with more airy coir.
General guidelines for germinating seeds using coir
In general we can conclude that coir is a powerful growing medium.
Crucial for a proper germination of a seed is humidity. If too dry the seeds will not germinate at all.
As coir is airier than most peat mixtures, you should use less water, but more often.
General guidelines for propagating cuttings in coir
Coir is a powerful growing medium. Crucial for fast root development is humidity. If too dry the callus will not be formed.
If too wet the cutting can start to rot at the tip. As coir is airier than most of the used peat mixtures you should manage your irrigation
with slightly less water per shift but with a higher frequency.
1. Prepare your tray(s). If re-used: be sure that the trays are clean and if necessary sterilized.
2. Put a single pellet in each cell of your tray. Place the opening (sticking or seed hole) upwards
3. Prepare the trays with the J7C by watering the pellets thoroughly for expansion.
4. Be sure that the water for rewetting is not too cold: warmed up to 20°C (68°F) speeds up expansion. With water at 40°C (104°F) it only takes 8 – 10s for proper expansion
5. Shower the trays with the pellets top down with small layer of water at the base, to improve expansion and save time
6. Seed the pellets or add the cuttings in the precut holes. Be sure that the cutting is positioned firmly.
Research has shown that a Jiffy 7C pellet is easier to manage when compared to alternatives.
There is no build-up of salts and you can add water more frequently
