It will compost and get some microbial action going if kept in a pile and moist….I've got a tarp of soil mixed up in my yard for my outdoor plants. Would it be better to keep it as a big pile on the tarp and mix occasionally until I'm ready for seeds, or just put it in the pots I'm gonna grow in now and wait for seeds?
I mean..hell.. there is Passion Fruit.........which could be fermented I guess.
