I'm not quite sure what you're ultimately arguing here?
Using clean spawn with oysters for example allows me to produce multiple flushes on large straw columns.
The columns only got tossed once the mushroom weight produced reduced the viability of the old columns in the space that a fresh column could go.
There's no trich in that mix because of the clean spawn and substrate.
"My own substrates consist of low nutrient density materials like wood chips and cardboard. Slightly soaked with salt."
Do you grow commercially or just hobby growing?
What sorts of results have you achieved?
Starving a fruiting body of nutrients is counterintuitive and illogical, your argument regarding contamination favoring the nutrients shouldn't factor in here if you consider the process.
"Stuffing these grains and sugars down the mycelium's throat is akin to how the meat industry pumps its cattle with hormones. It's just a unnatural solution that only the big boys with all this funding and equipment can afford to do."
That's a bit over the top, we're creating optimum environments for fungus growth and you criticize it like we're some meat farmers.

I'm a hobby grower. My point was methods like using salt or peroxide are extremely viable small scale. Contrary to the quite ridiculous arguments I see here stating otherwise.
I can also understand the confusion. I'm not arguing for complete malnutrition I'm instead arguing for common sense practice. If your mycelium isn't ready to handle contaminants or is in a environment where it can't then fix the situation in advance.
Substrates like straw, card board (wood byproduct), Paper, Etc. Make intuitive sense to people. However grain (starch), malt/agar, etc. Are counter intuitive for beginners with little equipment. Because they require immense amounts of equipment to sterilize the air and tools your using.
So your giving your advice out to the wrong people. If you want a clean and sterile environment get a lab. Otherwise you'll get a mouth full of trich.
Things like still air boxes are completely silly as well. That seems to be the number one go to for shutting beginners down. Instead of saying "Use low nutrient materials if you aren't getting good results."
I followed the common advice and I would get contams like crazy. Damaging my passion. When I stopped listening to the common pseudo scientific methods I instead gained results.
It doesn't matter how much nutrients your giving if they never make it to the mycelium for fruiting.
"That's a bit over the top, we're creating optimum environments for fungus growth and you criticize it like we're some meat farmers."
Indeed I see people trying to suggest using coffee grounds and other things because they offer good results. Good farming results. But again decomposer mushrooms work the easiest on things like corn husk, paper, etc.
A lot of people seem to ignore the complex requirements for growing and slap sugars at the problem. Instead of taking a step back and looking at the best long term solution for small scale growing.
(also 90% of edible mushrooms are grown in Asia, primarily china, and contain stupid amounts of heavy metals.)

I keep getting trich. It always appears after the mushrooms have pinned/fruiting. I'm using sterile technique (clean room, gown,hair net,gloves,mask, alcohol,Lysol, hepa filter. Anyway I just tried your method of extraction and salt. I really hope it works because they are otherwise perfect. Hundreds of pins and primordial. I did separate the infected tub. If anyone has any ideas or advice for this relative newly I'd be grateful.

Not trying to necro this thread, but after this I did some research.
-Different species of mushroom tolerate salt diffrently, some use in it their metabolisms (like how human kidneys use sodium as a required material for urination) and others don't but have protective mechanisms.
For example I've been cultivating oyster and have done some experiments. I took a culture and increased the salinity to about 300%. It took the oyster 12 days to die. These good results lead to me adding 2 grams of >1%SBC (less than 1% sodium bicarbonate) to a culture of oyster mushroom with the standard 5% nutrients.
The mycelium have literally reached the top of the culture. It's grown as thick as a carpet. Other species like shitake don't seem to mind such a small amount of SBC and perform only a little worse. But with a observable smaller chance of contam.
In regards to bulking stages; I now do a small amount of pasteurization (heating the water to boiling before I add spawn to feedstock), I think a small amount of hydrogen peroxide and a very small addition of either salt or SBC could also help reduce contams. Hydrogen because it would fight spores (not live organisms.)
I know pasteurization isn't boiling water (its keeping the water sub boiling), but compared to autoclavation it sort of is.
Anyway most bulk trichoderma is a matter of not adding enough spawn during the bulking stage (if you're getting grain, culture, or plate contams it's a matter of sterility. Either decreasing water content or increasing caution is enough to help stop this issue.)
Adding a small amount (>1%) of HP/SBC where applicable with very hot water should help you. (Don't mix boiling water with your substrate in a plastic or plastic lined container. Leaches microplastics)

me too! sounds like someone from the future that has figured out how to do things in a way that has perfectly achieved the goal im trying to reach. and although i just got the perfect makeshift SAB (which has drastically improved my success rate) id still be more than interested to hear about these low nutrient materials/procedures to simplify things for subsistance-ers like myself.

i’m as new as new gets. i’m so new that i’m looking at 10 tubs of various sizes and at different points in their life cycle, with various setups, in order to find my way in this hobby. 1 of the tubs is fruiting nicely, albeit everywhere but where I wanted it to (side, bottom) and i’ve got pins on 3 more, but there are another 3 that i’ve had to quarantine, because that bright white shaving cream looking mycelium popped up on my casing and being the noob that I am, i’m unwilling to let these tubs go. so, anywhere i’ve spotted anything that doesn’t look like the PE or MVP mycelium that i’m pet familiar with at this point has gotten absolutely covered in salt. and, so far, I have seen no signs of green nor has it spread in those tubs. i’ll report back if and when they actually produce anything, but so far salt seems to be the real deal when it comes to dealing with the invader whose name I shall not give credence.

That is what you call confirmation bias.
Salt is a condiment for your food not for treating trichoderma.

And anyway, trying to treat trichoderma is like trying to keep vultures away from a rotting corpse. By the time you see green, the patient is already dying. Actually, by the time you see trichoderma mycelium, the jig is up, but it's common for new growers to mistake it for "totally clean robust growth."
Trichoderma is everywhere, it typically moves in and takes over when a substrate has been compromised in some other way
