hmm I understand
I understand what you mean, I have tried the pre-heating method for the first heating cycle as well.
I would still end up stirring after the 3rd heating cycle, and come to a point where, after a heatup, and I split the time between the 'heated click' to the 'cooled click' in to 2 separate draws, I would still get visible vapor exhale on the first draw, and little to none on the second draw.
Then I would heat it up again for the 4th cycle and I would get way less visible vapor, even on the first draw. BUT if I stir it before the 5th cycle, there would be almost as much visible vapor as the 3rd. Hence why I feel the desire to heat it up for another 6th cycle and even 7th.
Perhaps I am being too greedy, trying to get those 'every last drop of vapor'. Or is it even vapor at that point? A Vapcap being a conduction vape, perhaps I'm cooking the herb so much, it is smoking? But I am not getting the taste of combustion, nor does the herb come out black.
