Growool Granulated Premium Rockwool is not a 'granulated' rockwool as such but more of a 'spun' rockwool making its appearance and consistency more like 'fairy floss'.

This 13.6kg bag will make up to 122L.

Premium Floc needs to be flushed with pH adjusted water set at 5.5 prior to use.

The pH of the nutrient solution should also be 5.5 for best results.

Like all rockwool media, Premium Floc has a high water holding capacity so it does not need to be watered very often.

Premium Floc is an inert, sterile medium well suited for horticultural use.

Care should be taken when handling rockwool by wearing gloves and a mask.

The rockwool fibres can cause irritation to the skin, and if breathed in they can also irritate the lungs.
