Hyuga pumice is a light weight volcanic rock which is perfect for soil amendment.
It is a natural, unprocessed product which doesn't decompose.
Hyuga pumice is porous and breathable which provides excellent drainage and air circulation for the roots.
It absorbs excess moisture in the media preventing root rot.
It does not break down easily over time, thus reducing the need to repot the plant frequently due to caking of the media.
 
Note: All 1 litre packs have been sifted before repacking into a clear ziplock bag.
