Expected more clouds with RDAs?

So first off, I'm a newbie builder. I finally got a successful build after a few tries, but I have to say, I'm a bit disappointed. I'm used to using a standard LR510, and I thought that vaping at .7-.8 on a RDA would increase my cloud but it's less, no that much less, but not what I'm used too with the 510. I used 28ga with about 8 wraps, (not compressed) dual coils on a Tobh, and am using organic cotton 3mm for wick. and the 4Nine copper mod. Even with the airflow the lowest it can go its so airy I have to do a lung draw, which I'm not used too, and it burns my throat sometimes. I don't understand how people are getting these massive clouds! When I tried the compressed coils I just got a burnt and horrible vape. Any suggestions?

Before anyone does, I would recommend that you post a picture of your build :)

The other thing is, don't expect to vape the same nic level on a sub ohm RDA as you would with your normal atty. I was using 12mg on a kayfun. With an RDA, I had to drop to between 3mg and 6mg and still got mad nic rush. First few times I vaped with 12mg and lung inhale and it was like satan ...... on my throat.

The other thing to consider is to use higher VG juice! Higher VG = more vapor. Helps lower the TH too.

And well. Vapor production comes with air flow. Can't really escape from that. And if you're really looking for huuuuge clouds, you need to open up the airflow and do lung inhales. There's just a physical diff in the volume of your mouth vs your lungs.

And lastly. Please please please please please have all the battery and safety knowledge.

K I'm out.

This, as well as the previously stated VG ratio.

When I first started dripping I was doing mouth to lung inhales as I did on my RTAs. Cloud production was meh. I then began to open the RDA up air flow-wise and doing lung hits. Bam! Clouds!

Now, for me anyway, I want a very airy draw with my RDAs.

what has been said already +

When you "compress" the coil it sounds like you're using a bit too much cotton. You want it to be free to move back and forth inside the coil, but just barely. It shouldn't tug the coil when you pull on the wick, and the wick shouldn't bunch up when pulling it through.

imo wicking is the real tough part to building your own coils. Too much and the juice flow is cut off and the cotton burns. Too little and the coil doesn't get saturated and you get a hot dry vape with possibilities for hot spots and hot legs.

Just right is like goldielocks, takes a few tries to find.



also, make sure you have some room under and around your coil for it to breathe. You need space for air to hit it.

agreed with everything said; i will add, OP, that although youre not accustomed to lung inhales, you might find that you will very quickly become accustomed to it. what was once an extremely airy dripper for me (the trident, dual coil/hole config) is now one of my tighter drawing attys. and its not tight, it just seems that way after i got more and more accustomed to lung hitting. once you open up your draw, theres basically no going back. its just too enjoyable with massive air flow.

and one other thing: make sure your coil(s) is/are directly in front of the air hole. if its too high, your TH will be increased exponentially. but at the end of the day, you may need some "dripping juice" (higher VG, lower nic%). i was an 18-24mg vaper when i used replaceable coil systems, but now that im all mech+rda, i am a 12mg vaper and i might even be able to go to 6 soon.

cheers

Along with the above recommendations, I suggest compressing your coils to be microcoils. Tight-touching coils allow for more consistent/even coil-on-wick temperature. Tighter coils heat more quickly and will have a smaller thermal zone temperature range. Coils lightly touching each other don't short out. Kanthal develops an oxidation layer, so as long as there is not significant pressure (depends upon amount of wire oxidation) between the touching coils, you are effectively insulated against hot spots and shorts.

Better airflow - align the top cap air hole(s) by the coil(s); enlarge your cap's air holes by redrilling them;

Make lower ohm coils if your batteries can safely fire them (enough amps);

Use the proper volume of wick inside the coil (not too much, not too little);

Higher vg e-liquid will all contribute to more vapor production.

Oh did I mention, don't over drip?

Unless I'm imagining things and happen to be the only one to do it and find that vapor production goes down the drill on a flooded coil. If so feel free to ignore me
I don't think your imagining things, I've noticed that also, even my friends who don't own e cigs have noticed that, I drip right before I hand it to them and a couple of them have asked why it doesn't hit as well on the first hit.

I'm going to try to adress all the issues brought up, Ok, so I took a photo of my build but I don't know how to upload here! Pffffft supposed to be a veteran member. Anyway, if someone could tell me how to do that I'd appreciate it. Ok, so juice.... I currently use a 50/50? by halo, and only ever use 6 mg. the only juice I use. Guess I'll have to find new ones :(. Secondly, I see above a large amount of wick and mine doesn't have close to enough based on that pick. As for the coils, the wick moves freely through the coil. Next build I will try compressed coils and see if that helps. I've been doing the lung draw with holes all the way open now, and right next to the coil, but the cloud hasn't increased. The photo above seems to be using cotton balls, does that work better than standard cotton string wick? Someone also asked what atty I was using, it's the TobH. Hmmm what other questions were there?

Cheers and thanks, leila
