And even within the same strain, if one batch is a bit dryer than the other, the dryer batch would require a lower temp and a more moist batch would require a higher temp, right?

For me, I say fuck all that shit. Wayyyy too much fiddling around for me. I just wanna simply vape and get blazed so a fixed vape temp within the vape range (365f-395f) from a great vape does the trick for me.
