Product Qualities Coir
• Easy resaturated with water
• Stable substrate if thoroughly composted / high Lignin
• High air-content, even when fine structured
• Fibres and/or husk chips further increase airiness

Jiffy Growblock
• Worldwide trend to use organic media (i.e. coir) and logical demand for
coir growblocks
• Compressed and dry block made of 100% coir
• Matches with automatic propagation lines
• 100% biodegradable with PLA netting
• Trials in both the Americas and Europe showed a stronger plant and
faster rooting in coir compared to rockwool cubes
