Propagation Media

Rockwool cubes or Coir Coco plugs? At Norfolk Lights & Hydroponics Centre we have propagation media available for you to purchase to root your cuttings fast. 

Horticultural Rockwool is made by combining volcanic rock, limestone and heating to high temperatures in a rotating drum which has small holes in it.  Rockwool holds more air and water than any other rooting medium with over 90% of the block being empty space.  This means that with the right water to air ratio in the block the cutting or seedling will have easy access to water, nutrients and oxygen.

Rockwool is inert and sterile and therefore does not react with the nutrient solution, which is vital in hydroponics.  Transplanting from a small to large block is also relatively stress free for the plant.

Coco Coir has many advantages - Click here, for more information on growing in Coco and scroll to the bottom of the page.

At Norfolk Lights and Hydroponics Centre we stock the Jiffy propagation pellets and blocks, a natural and organic alternative to stonewool blocks.

Growers are able to change from the tradional stonewool blocks to Jiffy coco blocks without significant changes to irrigation or fertilisation routines.

The Jiffy coco block has been designed is designed to hold slightly less water than a stonewol block to aid and improve early root development.

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.
