Yes I do, e-liquid is vaporized in high quantity in cloud chasing; so much so that it isn't practical to hold enough of it at the coil to produce a dense vapor in any way without juice movement in the wick medium.

Over wick and you get bad results, under wick and you get bad results.

Optimal wicking is such that juice flow equals vaporization rate. There is a really fine line here that is easily crossed. If you want to improve the clouds you make wicking performance is certainly something that needs close consideration.

--------

Coil type and orientation heavily effect how you'll wick, and to some extent if the coil position makes wicking impossible that position can be crossed off the list as a cloud chasing position entirely.

---------

Wick material choice can have a huge impact on cloud chasing too, solid mesh and cable have a lot of ability to back as heat sinks, and that can inhibit flow; a sharp difference in temperature across the length of a wick helps flow, where as a more uniform temperature slows flow of liquids.

Remember flow tends to move from high pressure to low pressure, heat tends to reduce pressure and cold increases it.

--------

Good luck

So question to that what if a bottom feed rda was used? Seems like that would reduce the importance of wicking because of the constant supply of juice to vaporize

I've been doing a bit of research on inhaling/exhaling.

The common thread in "good" inhaling is to use one's diaphragm. Singers and wind instrument players will know this one well. Use your diaphragm (it's the muscle that sits right below your lungs) to pull your lungs downward on the inhale first, then once it's extended fully, use your chest to pull the rest of the way. In short, your stomach should be extending first while you use your diaphragm, followed by your chest expanding at the final stage. It takes a wee bit of practice at first but it's not difficult to get the hang of.

The exhale part still eludes me somewhat. Essentially, you should be using your diaphragm during the first stage and then your chest but the speed of such seems to be down to personal preference and lots of practice. Mouth shape? In my limited experience your lips should be roughly the same size and shape as they would be if you were blowing into your cupped fists on a cold day. Extend your jaw slightly during the first part of the exhale and as you come to the end, pull your jaw back to its natural position, which will narrow the hole that your lips make and focus the last of the vape coming out of your lungs. Again, I have a limited experience in cloud chasing but I seem to get my biggest clouds this way.

And you know when you see cloud chasers blowing vape through their RDA's airflow holes just before they start inhaling? RiP Trippers says that he thinks this is to get some kind of momentum going. I personally think that they're "jump starting" their coils and getting them up to optimal temperature and producing vape before they start to inhale it. It maximises the amount of thick vape that the lungs are taking in. That what I think anyway. You can take my opinion with a pinch of salt. :)

Thats exactly what I thought its about heating the coils sooner not so much clearing there lungs because when I do that I can get a much warmer vape faster

RDA's still need to move juice through the wick to the coil; be it through a wicking material cloud under the coil, a wick of any type that passes through the center of a coil, or a shroud of wicking material around a coils exterior.

The best way to demonstrate that e-liquid moves through a wick is to do a macro coil and center wick it, then trim the wick to match the coil. This method restricts the quantity of liquid to on that which is present at the coil when it is initially saturated and nothing more. You will find that you will need to restrict draw duration seriously or experience dry hits.

In some atomizers you can make use of a drip well, others might do better with an up turned wick that uses gravity to assist wicking, still others may do best when the entire device is tilted to effect flow of liquid to the coil(s).

In every case, cloud chasing of any sort won't produce enough vapor from the juice that is initially in contact with the coil, more needs to replace it as it vaporizes, and needs to do so at an identical pace. To fast and you flood the coil (even in a dripper), to slow and your cooking wick and getting an overly hot vape.

There are happy mediums where not enough wick is as bad as to much wick. In terms of cloud chasing you want to vaporize as much fluid as possible in as short a time as is practical. A wick that passes through a coil or around a coil will have more contact area than a cotton cloud that touches only half of the coil. A larger diameter coil has more available surface area than a smaller coil of similar length. A larger coil can potentially vaporize more juice assuming it can heat the juice sufficiently.

This is done for a few reasons:

1. If using nicotine, nicotine is the harshest when it first begins to vaporize, so it reduces TH.
2. Some builds take awhile to heat up, so it's just giving time to get the coils hot, especially twisted kanthal at lower gauges than most people will do.
3. Just to make sure the coil is more efficient and at a higher temp before inhaling to someone's maximum lung capacity.

Plus it just looks cool.

Does it? I'm so use to seeing people blowing clouds and doing it myself, everything becomes just normal after awhile. After a while huge clouds start looking small and it's really hard to be impressed by anyone's clouds even your own. That's when cloud chasing can get dangerous.

I am dealing with that right now and it has gotten me really unimpressed with any of the mods or atties that I have

Sounds to me like it's time for you to start experimenting with harder builds and low resistance wire, so you can gain more surface area and still keep lower ohms.
Yeah I have built all the way to .15

I built a .07 but only did a few quick pulls

But I have some 22ga and 22ga flat on order to try that out you think I should try 20ga?

Thats getting really dang thick!!

I wouldn't try 20 gauge, 22 gauge it's ok for simple builds to keep ohms low and still have decent surface area, but if you're doing dual coils, you need to have your post holes drilled out or use an rda with dual positive posts or do a sleeper build.

With some builds you don't need low gauge wire to get really low ohms. I did a dual parallel coil on a sleeper build with 27 gauge kanthal and it is not really at a safe ohm range, I have another set up with 7 wraps on a 3/32 screwdriver using 24 gauge royal wires at .16 ohms and both these builds produce more vapor than simple 22 gauge builds amd even twisted 24 gauge and tripple twisted 28 gauge and 2 strands of 26 gauge twisted with 28 gauge etc.

Disclaimer: These builds are NOT for beginners and people who don't have the proper batteries to do so. There is a higher risk involved when you are pushing your batteries close to it's continuous amp draw and especially above. I'm not recommending my builds to other people. Build at your own risk.

Parallel coils always seem to do best for me, I've yet to try ribbon but it would seem to be an advantage in terms of mass to surface area able to contact the wick.

My biggest improvement in vape quality though has always come from nailing the wicking regardless of the build though.

I have a silly wicking idea in development, so take that as a tease and understand it might totally take a ride on the failboat.

Just curious if we're on the same page since some people get confused with dual horizontal coils that are parallel with each other and dual parallel coils that are 2 coils and each coil has 2 legs for the positive lead and 2 legs for the negative lead for each coil, equaling a total of 4 legs for both coils.

Easy simple wick that holds more juice and keeps the cotton away from blocking the wick and keeping the bottom of the coil exposed is just a simple single strand of cotton going through all the coils and making a complete circle.

Parallel coil: two wires that lay side by side and are treated as one might treat a single wire as you wind a coil.

Really bad picture of a parallel coil, sorry!
