Cannabinoids and terpenes boil at different points, so a session at 180 degrees delivers a noticeably different experience than the same material at 210. Boiling point tables with practical temperature bands are available at https://potentthcseeds.com. Lower settings favour flavour and a lighter effect while higher ones extract more thoroughly and taste worse. Stepping up gradually through a session gets most of both, which is why many devices now offer that mode.
