My VB2 performs awesome! It is NOT a bad device whatsoever in any way! Is it the best? No? Yes? Thats not the point of my post. Anyways...
For FLOWER I grind to a normal consistence, place a pinch in, press it in with my finger, pinch some more in,press that in so there is a nice amount in there....but not too much to where there is "thick" tension on the stir knob. i then place the cap on, start vaping at 2...then 3, and finish the last 2-3 hits on 4. 5 is reserved for oils. I can pull thick clouds out of my VB2 anytime i want from first hit till last, well...the last 3 hits are light...but visible.
As far as OILS go, only use SMALL amounts at a time, inhale slow-steady-mflb through your nose-like and that works well for me. AWESOME flavor. No thick clouds for me....but i dont mind because a small dab of good blonde wax gets me all ASDKASLGFKASD with the oil bowl. All-be-it i can not seem to remove the annoying white piece in the oil bowl.
SO!
Grind, pack a pinch or two in and press it in but not too tight or to where there is too much tension on the stir knob. Start her up to desire temp, once at desired temp take a few TEST PUFFS or use the THROUGH YOUR NOSE technique to get the air flowing through
