'Don't take the tape off. I've already read a post about this'

Agent, is this why you say don't tape? because of the one post? in my opinion, flipping the jars is more likely to cause problems than just not taping the holes. when you flip them, the cake will drop, and they'll suck air into the jar. i guess the air is filtered through the verm, and the chances of anything bad happening as a result are low, but it's still a higher risk factor that taking the tape off. in my experience, the tape does nothing.

for gases, the molecular weight is the only thing that matters. all volumes of gas 22.4L have the same number of molecules at STP. so, the heavier gasses go down. but, gasses also have a tendancy to mix almost completely. the higher concentrations move to areas of lower concentrations. so the oxygen will want to go out, and the co2 in. the air layer that is created is what speeds colonization.
