To fluff or not to fluff. That is the question?

Hey everyone,

I have heard of different ways to put your cotton on your rda and rta. Some people and YouTubers say that the cotton will fluff itself, while others say you must always fluff.

I personally fluff my cotton, just like the way the cotton wicks when fluffed. This is just my opinion.

I was wondering what everyone else's opinions were on the subject.

And as always, thank you for your input!

You have to understand what fluffing does and what you're trying to achieve.

The amount of cotton is a function of the ID of your coil. In a tank you may need to fluff and thin because the ID of the coil doesn't align with the juice intake. You might need more cotton in the centre of the coil than you do in the juice port. If you have a smaller coil, you may not need to fluff.

In an RDA the same thing can apply but for different reasons. You may want to fluff to reduce chamber size and increase flavour. Or you may want to not fluff because your juice level isn't going to be so high and you need it to quickly wick from the deck.

Morten Oen showed in one of his videos that the harder you wick (less fluff and less thinning) the quicker the juice will wick throughout your entire wick. But the more you fluff, the quicker it will saturate at the tips. The length of your wicks, from your coil to your deck, are also something you need to consider. I only fluff short wicks.

There isn't one answer to your question. You just have to understand what both things do and figure out if you need to do it for your RTA/RDA & coil.

When I used rdas exclusively I fluffed the ends but wicked very tight. When I got an Aromamizer Plus I had to change it up, wick a little looser and fluff the ends, then comb and thin the ends out to let more juice in.
I'm a firm proponent of fluffing, but in an rda it is not as necessary.

"Capillary Action" in 1 sentence:
The straighter, narrower, and longer your capillaries are, the better it works.

Combing your wick is not a bad idea. But when your fluffing thins out your cotton, all you've accomplished is to reduce the numbe of capillaries through which your liquid can travel up to the coil.

In my case, thinning out the tails was somewhat necessary to allow more juice in through the wicking slots. Made a huge difference.

It's a trade-off of some sort...

If you fluff a short wick, or if you put your cotton just on top of the holes, or only very slightly into the holes, you allow the liquid to freely pressure its way into the holes up to the point where it's then taken up by the cotton. That way the liquid has to travel only a relatively short distance through cotton = capillary action takes over at a late point, and that saves time.

Problem is, that only works as long as there is enough pressure. The more you empty your tank, the less it's going to be, up to the point when there's not even enough left in the tank to level itself out and still reach the cotton. If that's a concern, use a long wick that reaches through the holes and touch the bottom of the tank. But in that case, do not fluff before it touches the bottom, or it can ruin your wick. Better not fluff long wicks at all.
