BH, I'd start around 175°C and adjust up or down from there. I like using hand torn or a course grind w/ this. That way I can use a higher temp & the flavor sticks around longer. Although, if your searching for max clouds & max medication, a fine or medium grind works great. If the temps real high the flavor goes kapoof in that 1st hit, but oh what a hit. And the convection high from the Sup gives me that fuzzy in the temple kind of high I used to get from Sherlock bubblers.
