I think you should also mind another dimension: draw speed. Sometimes i combusted because i inhaled to slow while dancing with the red devil. Conversely if you dont inhale at all, you can be safe and never combust.
I was drawing slow. I'm finally starting to get draws with minimal lighter intensity:
1. No draw heatup until the whole center disc with fast circles until it glows a bit, not just a dot. Center blue flame just kissing it. Pull back just a bit from it to the cooler blue flame and move in a zombie-like pace, making circles. It should be barely glowing
1a. At the same time, super duper slow draw, similar to the milaana getting started but waaay slower. When you feel it, start to rip. I think of it as a vape where it'll get there when it gets there and I like that. Very relaxing.
2. Continuing to draw after the butane is done is the best thing for vapor production.
Once I "got" it, it's better than my milaana by miles.
Question:
I use the torch 420vapezone has on top; it doesn't like being held upside down. What is the torch he uses on the bottom?
