Question about drying residue

I have noticed that when I move my drying pot around- taking it off the hanging line and trimming the buds into nugs, or setting them out on a screen or into bags- I see a fine powder left behind.
I never noticed this when handling pot I bought in Holland.

I looked at some of the dust with a microscope and they appear to be the round heads of trichomes.
This is quite disturbing, since I want them on the smoke, not in the bag or tray.
Also disturbing is whether I am again doing something wrong in drying or handling the buds.
Why am I getting so many trichomes falling off?

because you are wet trimming good bud, hehe. try dry trim, cut your plant and hang it with the leaves so all the weight of the fan leaves and sugar leaves rests on the buds, remember how pot used to come in bricks? then trim it over a silk screen then right into a jar after a week of hanging. brick weed can still be just as potent, brick drying traps most trichs from falling out/off. plus a lot of scientists say that the oil on the leaves is different from the bud trichs and gives you a better and more well rounded high, also the buds will absorb all the nutes from the rest of the plant because its all intact, so this method only serves to increase potency

Thanks. That's helpful. I did trim down to the buds before hanging to dry.
Next time I will try letting the whole plant dry.
