it is a composter like a worm bin for phoenix worms
phoenix worms are the larvea of the black soldier fly.
They eat food scraps or anything edible. The reason you need
a special container like the biopod is because phoenix worms
create alot of liquid called "tea" when digesting and that liquid if it
over flows will kill your colony. Also when the phoenix worm is ready to
pupatte into a moth it will try to leave the colony and try to find a nice dry area
to do so. The bio-pod covers everything necessary to succesfuly culture these
grubs but it is pretty expensive so here is a link on how to make your own culture system http://blacksoldierflyblog.com/bsf-bucket-composter-version-2-1/
