Coffee?

So, what's "new" deal with coffee? I only find old "teks" which says "don't use it because it will contaminate". Yea, HPOO is also nutrient dense (sorry, english is not my first language) and doesn't mold if you pasteurise it.
I have around 1kg dry used coffee grounds each week. I have it on paper in open air, and it doesn't have any visible mold on it because it's dry in 1-2 days. I want to use it with coco, as I pasteurise whole substrate, because bucket tek don't work for me.

Skip the coffee. The nutrition comes from your spawn.

Grow oyster mushrooms if you want to use the coffee. Otherwise compost it

Coffee in a cup will mold in a few days. If your using grain you have way more nutrients than you need. You want your bulk substrates low in nutrient density and you spawn to have the nutrient load. If your bulking with a high nutrient load substrate it will slow down your fruit formation.
Slow like bod said. Skip the coffee and compost it instead. Also it can be acidic

There are many studies that clearly show higher nutrient substrate yields more mushrooms. Great examples are edible mushrooms like shiitake, oysters, lion's mane etc... Which I am also growing on comercial scale. I am that guy who want proof, which can be measured and things you say that can be verified. So if someone says "you don't need coffee" or "coffee will mold and HPOO too, because they're nutrient dense" that doesn't convince me. Because we know pasterisation is key here. Just an example tho.

Cool we're talking about hobby grows of psychedelic mushrooms. If you want to talk about commerical grows of culinary mushrooms go to that section. Like I said earlier leave the coffee out unless you are growing something like oysters

People tend to over complicate cubensis cultivation. They don’t need much at all to thrive. Some grain spawn, something low in nutrients to hold water (coir or hpoo) but still stay airy, a little humidity and some fresh air and they will explode if you have your substrate made well and a decent culture.
I don’t see how you can really increase from wall to wall canopies. More nutrients might theoretically be able to put out more mushrooms over several flushes but then contamination becomes a factor the longer you try to keep a sub viable. Proper timing and turnover will yield more in the long run than gong for more nutrients I believe.
