Compost Tea Spear Kit

An air/water spear and woven synthetic bag, into which the spear is inserted. Designed for dislodging stubborn fungi from a compost inoculum when brewing.

The kit consists of a woven compost tea bag with drawstring and an air/water spear. The bag is to prevent the compost substrate from clogging the pump while the spear is attached to the bypass hose of the Brewstar 2500 Assembly™ to deliver pressurised air and water into the bag to extract the fungi, propagules and hyphae from the compost.
