I've also vaped at 200-210-220 degrees... Although I'm careful...
But I have no idea what I did wrong yesterday... I think I was just too greedy... But I didn't feel like I necessarily pulled much more than usual.
But it really hurt afterwards...
The next morning I also felt that my lungs were still hurting.
and something else:
Somehow I have the feeling that my heating chamber is getting dirtier every day... Even though no crumbs fall and I actually only use the bong upside down and I'm careful not to turn it, small black spots keep appearing.
When I see your photos, they look almost new
