That’s very cool. I’ve seen a couple of things along those lines in my time growing in super wet climates, one is that often a fully seeded bud will sprout by the thousands while still on the plant, but not until the calyx splits open and the trichomes have well degraded which kind of coincides with about when they are fully ripe, the sprouts then drop onto the wet ground and put down roots. So then the trichomes prevent water damage before they are ripe… that’s cool.
The other thing I have seen is an accidental cross that is ridiculously dense and would be normally expected to be a botrytis nightmare, but its so frosty and solid that water doesn’t even seem to be able get into the buds and so it just never seems to rot, even in extreme wet conditions.
Personally I have found mould resistance among one of the most difficult characteristics to nail down, I am more or less convinced it’s mostly morphology🤷♂️
