This bag is used for the filtering of your Soil Trooper solution, and for filtering compost tea.

The bags have 450 micron holes [a bit less than 1/2 a miilimetre]
and are 32 x 30 cm

They can be used with most tractor sprayers, but may be too coarse for some pumps. Please check your spray equipment and if necessary use a finer filter before loading the liquid into your sprayer.
