Thats not exactly inaccurate.. You'll get the most flavor and potency with ripe and completely developed resins. Terpenes affect the smell and taste, some buzz. And the the trichs are the stuff we're trying to smoke for the "high". Less developed resins end up in shitty weed and less potent medicine. So yes, you want those trichs to change and mature. But by cutting the day light they receive, they produce less pot. If they think they are dying sooner they will focus and finishing seed production. If seeds arent present the seed pods finish off the resins. Do you follow? Do you know why the plant actually produces these flowers? Because she thinks shes dying at the end of fall/winter.
