Are you decarbing before extraction?
I’ve not looked at this in a couple of years, and don’t recall if that is a requirement
See: R134a hemp and cannabis extraction advice and comments
If so, what makes you think you’re dealing with “high terpene” extract?
The viscosity?
Decarbed oleoresin will be lower viscosity…
Decarbed extract will also never make “diamonds”.
Edit: all I recall from the demo was telling my current handler “fuck no! Nobody gets to treat our flower that way…”
