Bubble Hash vs Dry Sift

[Gjourney101]

I've been watching Mr.Cunuck and I seen him dry sift trim a lot. Anyone have experience with dry sifting, and is more potent/stable the bubble hash?

Same potency, better yield and quality with the bags

I used a small 160& a110 micron for a few years, bags are much better

Dry sift has been working well for me. It can take
longer but it doesn't get any simpler.

A trichome is a trichome. It's what you get with your trichomes that makes for different qualities of the hashes.
Every time you rub on a nug (HA!) you potentially knock off more than just trichomes. When you dry sift or make dry ice hash, you are working with a lot more plant matter that has more potential to break down and gunk up your nice pretty kief than bubble hash that, even under great agitation, breaks up much less.

Opinion:
Quick, first runs are better than successive.
Any way you extract from whole bud is better than dry sifting ground bud or making dry ice hash.
Dry sift and dry ice hash are much more like weed than bubble hash. A lot more earthy.
Which is better is opinion.
