the smell before harvest and the smell of dried/cured buds is not always the same. I've had buds change smell from harvest to initial drying to 30 days after harvest when it finally remained consistent.
fresh plant? like hay? could be a fast dry or just needs a couple weeks of curing. Some buds will smell and taste as they will once dried, others need a few weeks of curing. I don't think i've encountered anything that doesn't reach its endpoint within a month of curing, but that may not cover all of existence, obviously. If you get any sort of ammonia or pickling smell, that's a sign of microbial growth in your jar and likely sealed them up too soon. a 2-way humidipak can help, but also has limitations of how much water vapor mass it can absorb.
Some of the best tasting weed i've smoked dried in 5-7 days. So, maybe the conclusions about this by the community are merely the result of fog of war and normal volatility of competent outcomes. Anecdotal knowledge is usually full of holes and misconceptions. If you can find any real scientific research on it, that'd be far more reliable than what people feel just from growing a few plants in a basement and without a lick of fundamental science knowledge.
Water will evaporate through the path of least resistance. Flower has significantly more surface area due to non-flat surface compared to a leaf. So, more surface area = faster evaporation, in general. Leaves are also coated in a waxy cuticle that would slow that loss by comparison, too, but does have stomata, which would increase it, but limited. So, the untested hypothesis here is that in a dead plant water flows to the leaves because it dries faster and pulls (absorbs due to moisture gradient) moisture from the flower through the vascular system, which means it also has to traverse a couple permeable membranes on the way to the leaves. This is insane. You don't even need an experiment to rule this out. This is not the path of least resistance. Also, if it were true the leaves should be the last thing to dry which clearly does not happen. This is a great example of how anecdotal stuff is often wrong. 100% confident in something that just isn't true. Even makes it sound science-y, like the people that professed for decades that starving your plants of nutes the last 2 weeks reduces mineral content of flower- this is 100% wrong, but it was a long held belief that people still argue about today despite zero evidence to support their erroneous belief.
wet trim absolutely is not relevant here except for how it impacted how fast it dried. that can easily be mitigated through proper temp/RH. My buds takes 12-13 days to dry and i wet trim. If anything i'd wager there's much less loss of trichomes when wet trimming and handing the buds than when dry. Just look at anyone's trim tray and all the 'kief' at the bottom. I barely have any of that on my plastic liner covering a counter top. Trichomes are more resistant to agitation before it gets dry/brittle and more likely to remain attached. Therefore, higher starting point and longer to degrade in any noticeable way -- as long as you hold stems while you trim... People molesting the buds might strip away more, but even that can't be assumed, because you'd have to compare apples to apples -- you'd still knock of more dry brittle ones doing the same things over-handling the buds.
i don;t pretend to know why fast-drying ruins quality of buds. The human sensses cannot resolve that in any confident way. Might be able to notice an overall difference which may just be temporary. i don't see these people comparing to a control group and tightly controlling all other variabvles to reduce fasle positives. So not only are there senses unresolved for the task, but the methods for their conclusions are suspect too.
