Cultiwool X-Fibre Rockwool Slab 100/15/7.5

Create a strong, dense root network in a Cultiwool X-Fibre Rockwool Slab.

It has a porous structure that holds air and has a crazy ability to absorb water and spread water evenly.

This means roots are able to utilise your media fully and you get a solid root structure that can support a bigger, heavier yield.

• Pre-cut 1m lengths
• Rich root growth - airy media that holds water
• Complete control - no nutritional content
• Clean, sterile & disease free
• Does not lock out - any nutrients will be available to plants

It’s easy to use - your slabs come precut. Simply pop out the rockwool from any pre-cut holes you want to use and transplant in.

RHP certified - highest category for wetting up

Cultiwool stonewool holds the highest level of RHP certification for the initial pre-soak. With such a high ability to uptake and spread water, you get an even spread of nutrient solution throughout.

Overall, growth is incredibly uniform and you get a dense root ball that utilises your entire block.

Robust - holds its structure

Rockwool is known for holding its structure. You can saturate it and re-saturate it without it damaging the structure. It’s great in hydro - you don’t need to worry about bits of media clogging your systems.

No nutrient lockout

Unlike other medias, you won’t get nutrient lockout in rockwool. Any nutrients and water you dose with are available for uptake and take immediate effect.

Clean & Sterile

These rockwool cubes are known for being clean, sterile and free of diseases.

Ideal rooting environment

Rockwool is known for holding lots of water and for having a porous structure that holds air. This is the ideal environment for rich rooting.

Inert - complete control

Cultiwool rockwool has no nutritional content - it is completely inert. This gives you complete control over your feeding programme.

Fight algae growth

To improve water flow beneath the block, there are drainage grooves. These, along with the black and white foil prevent algae growth.
