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
