I been using a volcano for about 5 yrs....the best way to use it IMO

Try using a 2 1/2 - 3 FT long bag

Fill the weed chamber 3/4 full (about a 1/2 g), preheat the volcano 340*-350*.....place the weed chamber on the volcano turn the compressor on let the hot air flow through the weed chamber until you can see the vape..... then attach the bag.

normally the first 10 sec or so is just air .... not vape.....doing it this way eliminates the extra air

I normally get 3 - 3 ft bags of vape:vap_smiley: per load
