Trich on pastuerized woodchips

I spawned some G. junonius rye to some pasteurized woodchips with a layer of cardboard on top. The trich seemed to be one tenth the amount of myc, but now it's nearly half. I boiled water, poured it into an empty cooler, waited till the water was around 185 degrees, and let the cardboard layer and woodchips pastuerize for an hour. Is this too high of a temperature? After reading around, there doesn't seem to be an exact consensus for pasteurization temperatures.
It's also sitting in plastic tub with little air circulation (I'm not around too often to fan the tub) and some water droplets on the bottom, which may also be contributing to the trich epidemic.
Should I spawn the chips to more woodchips outside? I've read that trich seems to be nearly non-existent outside somehow. I want to keep multiplying my woodchips, so I'd probably stick them in with some soaked, non-pasteurized chips in a mesh bag and still the bag in a cool place outside. Good idea? Or should I just consider this tub a failed experiment?
5 to the shroomerite with the most supportive, detailed answer because I really want to get my outdoor bed technique down pat.

I probably could've phrased this better.
Dilemma Trich is overtaking my gymnopilus woodchips in a plastic tote. Should I transfer to moisten (but not pasteurized woodchips) outside? Reading around, trich doesn't seem to thrive or grow very well outdoors. Also, is it a good idea to mix the colonized/trich woodchips with moistened woodchips in a mesh laundry bag outside? They'd be sitting on the dirt in a shady place.
How can I be a better mushroom cultivator? Was the pasteurization temperature (starting at 185 degrees) too high which caused the trich to thrive? Or was it simply the plastic tote with no air circulation that helped the trich? There's also a little leaf litter mixed in.

Just put it outside. See what happens. Unfortunately I've seen trich thrive outside too, so it's a gamble either way.
Pasteurization sounds alright. Adding to 185 would cool it down quick. Just make sure it doesn't go above 160 for 10+ minutes.
How to be better? Clean spawn. I guess maybe keeping the air exchange up woukd help too.

I'm planning on doing the tote bag thing, so it'll be it a shaded area, exposed to a slight amount of dirt, but also not in the ground, so there'll be plenty of air exchange. The temperature fluctuations may be a problem though.

I just boil the water, add it to the cooler, toss in the woodchips, and the temperature stays pretty constant. For my own future reference, what's the temperature range for pasteurizing woodchips and straw? In the old threads I've read, there seems to be inconsistencies.

Doesn't a little leaf litter and dirt benefit the mycelium when you spawn it to a woodchip bed? Why would a few tiny bits of leaves cause problems?
Also, I'm getting these woodchips from a friend who has a company drop off piles of woodchips on his property. I've read that the best way to age the chips is to let them sit in a thin pile, covered by a sheet. These chips were just giant piles and may have already had other bits of bacteria/fungi growing on them, so I did my best to scrape the ones off the top. Maybe I should consider finding a new source for woodchips?
