Mold in early stage of casing transfer, solutions?

Heyas,
Well, my first grow here, and I went with casings. The jar inoculation was 100% successful without any contamination, 8 jars. I transplanted them to casing containers, small tupperware, and some larger aluminum trays, but I guess it was too humid in there, and mold quickly formed within a couple of days, please see the picture. My question is... is it okay to just clear off this top layer with mold, and then add in some more coconut coir, verm to absorb some of the overabundance of moisture, and hope for the best? That's basically what I did. I'm wondering if you think it will work out okay :p.
A second question I have is: I've read that the mycelium growth/casing phase needs basically hardly any fresh air, and has to stay pretty humid. That's basically what I went for, but still mold formed fast. I pasteurized the substrate first. It is probably definitely too humid, so I made some changes on that front. Does anyone have any other advice for avoiding mold in this stage?

You've been reading something old as hell that's led you to use the word casing incorrectly. A casing layer is a layer of light, non-nutritive material on the top of the bulk substrate that's used to regulate moisture loss and provide a pinning surface. You have bulk substrates. They appear to be uncased.
Where are you seeing mold? If you have mold you can't just remove a layer of it and call it a day, that's not how mold works. Mold = project ruined, no way around it.
I don't even see any mold though. I think you need to do a ton more reading so you're not doing things all willy nilly.

Well, I think I'm 100% sure that white/gray growth on top of the substrate is not mycelium. I just transplanted them two days ago, and the mycelium is still an inch below. So, mold?
Thanks for the casing clarification. I thought it was a term that just meant spreading the inoculated jars apart into a larger container, and letting that fill in, then pinning. Will have to do more research.

I don't know, but passing a black light (UV) over mushrooms enhances their Vit D properties, so I assume Uv isn't harmful to mycelium. However UV has anti-bacterial properties in the lab:
 "A low-pressure mercury vapor discharge tube floods the inside of a hood with shortwave UV light when not in use, sterilizing microbiological contaminants from irradiated surfaces."
So if you feel up to the experiment...

Oh well if you're sure, no point in us checking I guess..

Here's a bigger picture if anyone wants to take a stab at guessing. Probably have to right click and 'open image in new tab'.

I'll try it at some point, even if only to rediscover what the experts are too busy to explain.
