This worm composter works like a funnel: the GFT in it at the top. And over time at the bottom the worm compost out. The compost worms are mainly located just below and between the last layer of waste.
Because the WormBag is quite large, the worms have some protection during cold and hot periods. But here, too, composting will decline in the winter.
The breathable fabric allows excess moisture to evaporate. So that the contents do not get too wet quickly.
In the video below it is explained and you also get to see how to assemble and use the Urban Wormbag.
