Can someone explain the best way to draw with a carbless stem with no condenser tube? How does the technique differ from using a normal DV product?
In your regular stem with a carb or as George likes to call it an "Air Port"
, outside air is drawn in through the hole and with the hot air that is going through your tip and material, the two combine, and then, condense down to make vapor.
With a glass stem or similar that has no carb/air port, your mouth basically takes it's place.
The best way and position to draw will be different for everyone ultimately.
For a lung pull, I would try this trick to zero in on what your Sweet Spot would be though.
Heat your Cap to where you're ready to begin drawing.
Now place your lips about an inch away from the stem where you will be drawing through the opening.
Now slowly move your lips closer and closer to the opening of the stem, drawing air into your mouth with a fair amount of suction.
Pretend that your lips are already on the stem and you are literally trying to take a lung hit.
Likely somewhere around a quarter of an inch away or a hair closer you'll start to see vapor being produced and moving through the stem toward the opening even though your lips are not actually touching it yet.
As you get closer, you'll notice that the cloud of vapor in the stem gets thicker. You will also more and more definitely notice the vapor entering your mouth and on its way to your lungs.
The goal is to just lightly touch your lips to the opening of the stem so that contact is barely felt and light enough that outside air can equally enter your mouth along with the vapor your drawing through the stem.
From there it's simply a matter of adjusting the vapor vs air ratio, by adjusting the power of your draw, and the amount of contact your lips have with the stem opening, and you'll find that sweet spot where the vapor begins to hit your tongue and lips NOTICEABLY COOLER than room temperature air.
I would say that's a perfect way to gauge what your sweet spot is for a lung pull.
If you do mouth pulls, the technique is similar except you're sucking vapor through the stem first then inhaling versus just straight up inhaling from the stem.
I hope that helps. This was more odd to try to explain, than it sounded in my head, as I initially read the question.
Happy Vaping!
