bokashi

1st Bokashi Batch

Hey guys, my bokashi system is more or less operational by now. After two weeks fermenting the papers in plastic bags, I laid them in the sun to dry. There were some air pockets in the plastic bags, which resulted in a few colorful fungi at some spots of the paper (I think Nestor had the same situation).

For the composting tank I found this 8L bucket (including airtight lid), a strainer with a slightly smaller diameter, and plastic drain valve.IMG_1447 As you can see in the picture I already cut off the handle from the strainer, and dented the grid so it fits in a stable manner at the bottom of the the tank.2014-06-01_13-05-26_515Subsequently I made a whole at the bottom and screwed in the valve (optionally you can use some Teflon tape on the thread to make sure there are no leaks).2014-06-07_12-19-57_849So this what my ‘final product’ looks like. Time to start filling it up!

valldaura walking path

we were welcomed with open harms and dirty hands by nuria ;)

after a short visit to the main building, green fab lab, woodshop, the kitchen and the property we started the preparation of one of the most important tools for a urban farmer. well for every urban , I would say, since you can include here cats and gods :p the bokashi system.

first we need to make a starch base. we used rice and shake it with water. 1 clean jam glass + ⅓ of rice +⅓ of water + ⅓ of air. shake it, take the rice. leave the jam glass lousy closed (must breath) for 15 days in a dark, ventilated and fresh place.
