Harvest nettle - from tip to about 1 ft off ground.
Chop finely like herbs for a salad.
Mix in a barrel 2/3 full of dry nettle and fill with water (about 80% full).
Top with agribon cloth so to let it breathe but keep out bugs.
Stir twice daily for 7-10 days. foaming will begin 1-3 days in and then slowly subside.
Remove bio material and store in cool dark place.
