I could not get a good extraction for vaping - too weak. I ran the same VG/PG three times (3 oz good bud). It just does not absorb enough cannabinoids to be a good vape. It was part of the reason I went to the trouble to build a rosin press. Now the big problem is to get a disposable cartomizer/tank that works well with rosin thinned with EJmix, Puff Magic and/or terpenes. A lot of them I have tried burn on the first firing and then they taste like that the whole time. Testing is slow because after a couple of hits I am too high to continue testing objectively. I have a pen now with variable power and that seems to be helping but I have not found the magic combination.
