Hot / warm water all the way.
I am boldly predicting hot/ warm water will be in third place though.
Why hot water?
- I feel vapor needs moisturizing/ humidity MUCH MORE than it needs COOLING. Hot water moisturizes vapor passing thru it more than cool or cold water. See the laws of physics.
- Our vapor starts out at 350 - 440 F max temp, so 500 F lower temp than combusted..
Combusted herb range:
500-700°C (932-1292°F) Is the combustion
temperature for marijuana.
Combusted herb definitely needs more cooling help
- cooling vapor causes it to condense out. The more you cool it, the more that condenses. In an alcohol still, the cooling coils condense the alcohol vapor into liquid.
I don't want my vapor condensing out, I want it in my lungs please. Hot/ warm water condenses out less vapor than cool/cold water.
AND, having less condense out gives you more flavor from more vapor coming thru
- I find the vapor from hot/ warm water bubbler to be MUCH MUCH easier on the mouth/throat/lungs. Kind of like a "Vicks Vapor rub vaporizer" effect. It is warm and humid and soothing.
From my " mythical smoothness/ harshness scale ". Goes from minus 10 to plus 10. 0 is neutral.
minus 10 -- smoking a joint
minus 8 - smoking with bong
minus 5 - minus 1 vaping straight without water -- range of vaporizer makes / models
Zero -- vaping thru cold or room temp water
Plus 4 -- vaping thru hot / warmwater which actually feels good/ soothing. My mouth, throat, lungs feel better after vaping.
With cold water vaping, that vapor still dries out my mouth, throat, lungs.
It will be interesting to see how the vote stacks up...
