Rockwool
Rockwool is completely sterile, non-toxic and light weight. 1" rockwool cubes are ideal for starting seedlings and cuttings, once rooted they can then be transferred into 3" or 4" rockwool cubes. Please note: rockwool has no nutritional value, so it is important to pre-soak cubes with a weak nutrient solution such as formulex.

Diatomaceous Earth
DIAHYDRO (Diatomaceous Earth) consists of the fossilised shells of algae (diatoms) that lived millions of years ago. DIAHYDRO is produced from natural diatomaceous earth of a fresh water source. Products containing saltwater diatomite can contain high levels impurities which signifiantly reduce the positive characteristics of diatomaceous earth by clogging the diatoms and reducing absorbency potential. Diatomite is extremely high in Silica (87-94%), an essential component for growth of plants and strengthening of cell walls.
