I have similar spousal issues. We've been consuming for over 40 years. I've tried and given up on vaping flower in the past, but after some recent experience with doing dabs with an axial coil/banger, I thought I'd give it a shot again. I got a Runt, had some trouble getting consistent results...
I'm at 640 on my WE with no water, I find any water forces you to inhale harder, which reduces the effective temperature. I was closer to 700 with water. I find it's not harsh at all without water.
“Different glass will effect airflow as well. Some of my pieces 730f is perfect for meand others 685f”
I found when I use mine without water I can go with lower temps because it’s easier to draw slowly.
