I agree.
Often i have been vaping and blowing bigger clouds than another person using a lower resistance coil than i was and using 3 times the amount of power than i was.
There are three things goes into big clouds.
Good build.
Right amount of power
High vg juice.
I usually vape a Kayfun lite plus at 8-10 watts.
Where most people vape 50% vg. I DIY juice that is 70-80% vg
The vg of mine is 93% vg and it most definitely makes bigger clouds, I can't believe on one has mentioned vg content! Thanks for the input Two_Bears
