Apparent contradiction?

After searching for and reading many posts by RR and some other old hands in the community, it seems that standing air is one of the leading causes of contamination in the spawning/casing phase.
However, I've also read extensive advise suggesting that spawn runs and casing colonizing should be left in the dark with minimal FAE (while allowing for some gas exchange) to encourage mycelium growth.
Thus, does this set up bulk spawns and casings containing coir (60/40) for contamination? I now realize that coir is unideal as a casing material. I'm just wondering whether my coir/verm casing left in a monotub is asking for trouble, and whether there is anything I can do as an added safemeasure.

that's a good point you bring up. maybe if you wanted to be safe about fae, get an aquatic air pump. theres a tek on here to make a filter box to put it in. you could run the tube into the mono tub and it would force the air out of the polyfill holes. I've never done it before, just an idea. maybe check the growlogs for monotub and see how many flushes people are getting,and what their contam rate is etc.

You want a very small amount of gas exchange during colonization. At fruiting, you want a much larger amount of air exchange. It's not a contradiction, but rather different phases of the life cycle. If you had lots of air exchange during colonization of a substrate, the mycelium would consume too much of the substrate. We keep CO2 levels high for that reason, and then lower them with massive amounts of air exchange at full colonization, which brings in two major pinning triggers at the same time. RR

Correct me if im wrong here because this is how it makes sense to me, but i wouldn't think its a contradiction because when the mycelium is colonizing creating a bunch of C02 as it slowly eats eat the substrate and uses the little bit of fresh air it needs. So that box becomes a box full of c02 with a small amount of fresh air, and not just a bunch of standing air which would normally just be asking for contaminants

Ahhh, so the mycelium's production of CO2 keeps enough air moving to avoid contaminants?
When I read the posts it just seems like ideal parameters for mycelium colonization (some gas exchange, no FAE) were also ideal parameters for contamination. I guess that's why we aim for a slightly higher pH and a non-nutrative casing layer...
