How does the dry verm layer stay dry with evaporation? (PF-tek)
|
|
The subject title pretty much contains it - I'm wondering how the intended dry top layer of verm, important to be dry in order to prevent contamination coming in from the top - how is it this works in theory because does not moisture condense on the verm through the sterilization process - eg warming up the water within the jar?

hi, good questoin. i think the verm acts as more of a non-nutritive filter... there may be water there, but there is no energy available for growth of anything that might get in. contaminated would have to somehow cross your layer of verm and get into some flour in order to grow.

The fine verm is a barrier against contams. It won't feed then, and they have trouble working their way down to the good stuff.

hey, is it necessary if the holes are taped up with micropore?
