3 dry quarts manure
1.5 quarts verm
10 grams calcium powder
6 grams bone meal
6 grams blood meal
3 grams powdered kelp or seaweed
~1qt water(more or less to reach field capacity)
myco bags, .5 or .2 filter patch type
6"zip ties
wbs grain spawn, free of contaminants
add all dry stuff, slowly add water til you get the right consistency and a tiny drip of water runs out when you squeeze a handful. Put a quart of substrate in each bag, roll the bags up, don't seal, use a rubber band poster style to hold them shut. Wrap the bags in an old towel or t shirt and place in a pressure cooker without submerging them, use no more water than you do for grain in your pc. Cook the bags at 15 psi for ninety mins - two hours. Spawn inside a glove box or in front of a hood with a cup of spawn per bag, twist the top up and seal with a tight zip tie, careful not to obstruct the filter.
once they are fully colonized open the bags, mist very lightly and poke a good bit of pin holes or small slits in each bag all around the mid section. Tie the bags back with a rubber band or bread tie. Mist and fan daily until pins form, then just harvest at the stage you want.
clean spawn is the key, start on agar if possible.
