Why sub ohm? clouds can be made over 1 ohm

I have always found the easiest way to perfect your setup is to have 2 of the same atty and a-b compare your changer, reject the least favourite and go again.

This is something I try to do sooner or later

you have 2 of the same atty
how extravagant

So thicker wire provides more resistance and will need more wraps. As such you can get more vapour and flavour in general?

So coil design plays a large role then as well as wrap amount and wrap size?

Thicker wire produces less resistance so more power is needed to heat the wire to the same temp as thinner wire.
The thicker wire will give you more surface contact with the wick so more juice is vaporized, so bigger clouds and flavor.
There are many other factors like airflow and coil geometry that effect vapor production and flavor as well.

The problem with thicker wire, while what you say is correct, is that it takes longer to heat up, and longer to cool down. As such, it requires a different approach to vaping, where it is pointless vaping for the first second or so until it heats up, and the power needs to be off before you finish *drawing*, or the juice will just caramelize on the coil. Which is not good.

Just my tuppence.

Thicker wire will give more contact area per wrap, more wraps of thinner wire will.

a lot depends on what mod your using
vw/regulated mods were you set the watts there will not be much diff between a 1.8 ohm coil and a .5 coil at 20 watts
mech mods were its just a batt and switch the 1.8 ohm will only use about 10 watts and the 0.5 coil will eat 30 odd watts
peps with series mods that cloud chase tend to build above 1 ohm as they have more voltage to play with and want the bigger surface aria
the thinner the wire the higher the resistance and the quicker it heats up
hope that helps

Thats pretty much where ive landed peter12..

less is more when it comes to wicking, if using organic cotton pads, if you cant tug the wick back n forth under tension inside the coil without it tearing or pulling the coil out of shape, your using too much


fwiw in my limited experience
while some utubes etc will suggest 3-6mm width of a cotton pad to roll to wick a coil 3-3.5mm in diameter
i would suggest more like 2mm of a well expanded pad,,

rolling with the palm of the hand of a paper towel in one direction (ie away ) on a flat surface is the easiest way ive found to get an even roll from a slice of a cotton pad.

For most atties I do prefer a smaller diameter wick.  for example the kraken (when I wick with cotton, i know, i know, it;s heresy, but great for some liquids) I use very thin wicks as the cotton will expand and create a choke in the wick holes if too thick.  Chokes can also occur inside the coil on any atty.   Aim to have your wicks uncompressed and able to pull through the coil with only a little resistance.  They will swell when soaked with juice and if too tight will deliver juice to the coils at lower than optimal speed. 

As for wire gauge, kanthal is easiest to handle (IMO) from 0.35-0.55mm.  Any thinner gets springy, any thicker takes a lot of strength to coil effectively.  One widely unmentioned variable in wires is that thicker wires will result in a cooler vape than thinner ones.

Steam Engine has a good resource in this link that will tell you not only the max and min resistance your (regulated) mod will fire, but also the "sweet spot".  This is the resitance  where your mod will fire at max power while not stressing the electronics contained within. 

As always, please make sure you are using cells that can handle the current drains you will subject them to.   This AAEC post will give more info on which cells to use.

Say what? People with series that cloud chase start about 0.2 up to about 0.3, a whole ohm would be a bit shit tbh lol.


1ohm is for regulated or other vaping, not cloudy on unregulated bro

Still love a bit of 20G on a mech too, much thicker denser clouds than skinny wire

opps i got it wrong 
what have i seen these huge coils in
