I disagree with your assessment. There is no combustion or burning happening at 220C. It’s less flavourful than 195 but isn’t significantly different. I’ve assessed this with a Crafty and Arizer Solo II vaporizer.
That seems really low. I'm not proficient with marijuana and all its forms so bear with me.
But I would imagine even smoking a joint would go well past that temp. And people been smoking joints for decades with desirable effects. When I ask Google what was the temperature of smoldering it said 450 to 700 C.
Granted I don't entirely understand what's going on in this picture.
