The Jiffy Coco-Block offers hydroponic growers the first natural and organic alternative to Rockwool blocks.
The Jiffy Coco-Block is manufactured from coir (coconut fibres) at a purpose built facility at the coir source in Sri Lanka. The coir particle sizes and structure are carefully manipulated to replicate the drying curve of stone wool, allowing growers to change from the traditional stone wool blocks to Jiffy Coco-Blocks without significant changes to irrigation or fertilisation regimes. The Coco-Block is designed to hold slightly less water than a stone wool block in order to improve early root development and establishment compared to stone wool.
The coir substrate remains stable and does not degrade during the growing cycle, providing perfect hydroponic growing conditions. The substrate acts simply as a carrier for water, nutrients and plant roots, allowing the user to maintain exact control over the fertilisation levels throughout the growing cycle.
The substrate is wrapped in a fine capillary fleece to ensure the coir fibres are contained in the unit and do not enter the growing system whilst in use.
Available in 7.5cm (3") and 10cm (4") blocks and with preformed plug holes to fit the 30mm Jiffy-7C coir propagation pellets, allowing seamless transfer from the initial propagation stage and fast root establishment.
