Thats the effect a number of us have seen including
@Maritimer @Krissi Carbone and others. Looks like more trichomes but probably more so longer trichomes that fall all over themselves.
Krissi calls it coralling since it looks like sea coral.
I agree with the point that the droughting paper was a pretty limited study, and that point was raised in the droughting thread, but I think we have enough anecdotal evidence that there's certainly something going on with that process.
So, use it, don't use it, whatever, but like bud washing, many of us who have tried it once, now do it repeatedly.
