Growool Loose Floc – 6.75kg Bag

‘Premium Floc’ is an expanded bale of rockwool that will make up about 36 litres of medium.

It is not a ‘granulated’ rockwool as such but more of a ‘spun’ rockwool making its appearance and consistency more like ‘fairy floss’.

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

Once this is done allow the rockwool to dry out so it is moist rather than wet before transplanting seedlings.

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.

The rockwool fibers can cause irritation to the skin, and if breathed in they can also irritate the lungs. It is recommended to wear a mask and gloves when handling this product.
