I'm really liking this PN Pro more and more. If you want taste, stick to temps 1 and 2, but if you pack it tight, midway the taste will diminish, but you will be rewarded with abundant vapor.
To give you an idea of how much herb I'm packing per bullet, it's about a Solo stem packed tight with a little pinch on top. I have tried vaping the ABV in the Solo (not m105) on 6 after a full session in the Pro, after letting it preheat, I pulled a wispy cloud. I'm confident the Pro extracts just as well as the Solo.
I've noticed, once the heat has really penetrated the herb, if you want clouds, pull stronger than you're used to with the PN; the heater keeps up much better and there seems to be more concentrated airflow with the o-ring in place, which results in more vapor and me happy
Is the heater only at the bottom? Are the sides of the chamber heating as well, like the Inhalater?
