Some climates may produce better yields than others, some may have more potent than plants others, some may result in different cannabinoid profiles. Not sure what you are asking about on the landraces.
You are so close!
What I am saying is that what you call yield (I assume measured in dry weight) is the measurement by which you determine success is irrelevant to me. I can grow a 4 pound tent any damn time I want. But it would take us 10 years to use that. Trust me, I've done it, and it goes to waste.
What I want is quality.
"some may result in different cannabinoid profiles"
I am in the search for THCv. The bit about landraces is meant to explain why I am looking at climate tweaks to help my journey. Minor cannabinoids have all but been bred out of the current hybrid offerings commercially. But they were there in certain pockets of landraces. Developed due to local environmental factors and thousands of years.
So if I start looking at a Durban Poison for example, why does it have THCv? I don't think anyone truly knows, only hypothesis. But the climate is surely different than the mountains of Afghanistan.
We also have evidence that cooler night time temps effect many plant processes. Could it provide pathways to minor cannabinoids as well as flavonoids, hormones, and enzymes? Dunno. Wanna try.
I really don't think I am hurting anything with what i am trying here. I'm on Version 2 of my Raspberry Pi 4 system controller. With it, I can perform the VPD calculations and control RH to match current temps. Sound cool enough?
I want total control over every aspect of environment, just that simple. I realize this is not necessary for big yield.
