I remember reading an research article for an experiment that investigated pinning formation reactions to different light color temperatures and light intensity. The oysters they exposed to the highest kelvin rating and the longest exposure time tended to go hog-wild with pinning, however that cohort of blocks couldn't sustain the amount of pins it produced and ultimately had to systematically abort pins to focus on fruit bodies that had a higher chance to sporulate. The study concluded that one of the limiting factors of sustaining these pins from this cohort was the amount of nutrients available in the substrate (they were using smaller than 5 lb blocks I think).

Also, I read this article back in 2017-2018 so I very well could be recalling this incorrectly and/or it could be outdated 😅
