flip your jars onto their lids
when do you think the best time to do this is hip? my friend tells me he has een flipping them once the top ring of substrate, bordering the verm barrier, has been fully colonized. his thoughts were thats where the contams could come in when the verm gets shifted around and having it colonized would keep em at bay. also seems to time nicely with when the bottom is just starting to colonize
is that too soon to early or does it not really matter all that much?
