I dry to about 55% (just dryer than curing, leave a bit of moisture to help freeze up chlorophylls) then tubed, frozen and run. Any aging or heat looses terpenes and decarbs and that's very anti shatter. Aim to purge no higher than 100f film temp for best terpene retention and least...
Its possible with fresh, non aged (decarbed) material, key is to extract with super frozen tubes leaving a lot of garbage behind that would otherwise be dropped during winterization.
Well worded and imo accurate.
Not sure any amount of mixing the butane, venturi, prior to it hitting the material would have an effect on it's path through the material.
This is a firewall and should only be penetrated by a licensed contractor.
Mold remediation is not the cheapest thing, so beware of the exaggerated potential for black mold provided your biomass is significant and or air not exchanged often enough.
