Medium compost tea bags (400um)
$8.00Price
Reusable nylon 400 micron bags, 12" deep * 4" wide, with draw string.
Ideal for making 5 gal batches of compost tea or extract.
400um is the recommended filter size by Dr. Ingham for filtering out particulate matter that could clog nozzles, but letting microbes through in to solution.
Typical 5gallon paint strainer bags are 250um, which restricts the transfer of larger fungal hyphae and nematodes in to solution.
Wash after every use.
