Description
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'.
Flushed with pH adjusted water set at 5.5.
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.
