Envirostraw Hydraulic Growth Media (HGM)

EnviroStraw’s hydro-seeding mulch (Hydraulic Growth Media (HGM), is an innovative hydromulch product made right here in Australia. Formulated from annually renewable natural fibres, and including bio-stimulants and a bespoke blend of 22 species of bacteria and fungi, it is designed to rebuild disturbed soils on construction sites. Better outcomes are ensured with improved water use efficiency (WUE) as the product requires less water to apply which helps reduce costs. Using HGM allows fifty per cent more mulch per tank load which means spraying 50 % more area – less time filling tanks and more productive days.
