Not true at all.
Depending on the trichome head size too fine of a screen can get clogged very quickly and not let any trichomes through. Doesn't have to do with the quality at all and more so trichome vs screen size.
The screen on my Space case does not allow anything from my pink Kush to fall through. Yet I can drop in some XJ-13 and it drops tons of kief. When examined under magnification you can see that the pink Kush trichomes were plugging each screen hole effectively.
I agree, but all screens will eventually get clogged, which was my point.
We're using very sticky material that sticks to metal, all metal that manufacturers have tried so far anyway.
Even a bigger screen size that lets particulates through will eventually get clogged up.
You should be able to see this develop under magnification as well.
I understand that trichome sizes vary.
But trying different grinder manufacturers screens at this time won't IMO have different results, we still need to brush em out from time to time or they will clog over time, be it your SC, subways SCS, or the Gr8tr.
