Its as much opinion as how you like your hash or how mature you want your resin glands before harvest,
Some people are even terp sensitive and will opt for less terpy hash, easy fix would be pressing at higher temps.
And also i think alot of people are using shitty herb for rosin that is low on terps in the first place,
The age or maturity of the buds is something most of us don't consider in these discussions. Thanks for bringing it up.
I think it has to make a difference, just like the moisture level in the buds. Its no scret better buds equal better rosin, we know that, but theres a lot we dont know, at least i dont, lol.
Your not going to get clear rosin from mature amber trics. And I'm guessing there is a relationship between terpene levels and bud maturity as well. 3 month old buds generally make darker stiffer rosi that doesn't butter easy.
Does the terpene peak coincide with the changing of the trics from clear to milky, or from milky to amber, or completely amber? Not to be confused with how soon you press after harvest, this is more at what maturity the buds were harvested. I'm thinking the peak terpenes come earlier rather than later. But idk.
