Been smoke free for almost a year. Have a provari with natilus mini and a couple protank 2's. I hear so much about kayfun and am thinking about trying to do that and build my own coils. It's all kind of confusing and I don't know where to start. advice? I don't even know what to buy.
If you're interested, I say go for it. It's not that hard, and I personally find it fun.
I got my first RBA (ReBuildable Atomizer) a few weeks ago, and it's gone great. I got EhPro's clone of the Kayfun Lite Plus, v1 (v2 is more common now, and just as good, if not better. It has an extra airhole), and it's treated me very well. In addition to the RBA (also called an RTA, Rebuildable Tank Atomizer), you'll want some resistance wire, and I would recommend 28 gauge Kanthal A1. In addition, you'll need something to wick. Organic cotton balls work, as does more expensive Japanese cotton. I use Rayon, or Cellucotton, from Sally's. You'll need something to measure the resistance of your build, and your Provari should work if you're keeping the resistance above 1 ohm.
An RDA is a Rebuildable Dripping Atomizer. They normally don't have any tank, have fewer parts, and easily-accessible build decks. They're also fun, but good for "around the house" use because you do need to drip liquid onto the wicks and coils regularly (not after each hit, but after a bit). In some respects, they're a bit more forgiving than an RTA, since your wicks just need to hold liquid, not draw it from the tank, to the coils. If you do get an RDA and plan on using dual coils, you might also want 30ga Kanthal. This will heat up more quickly, if your device is limited to 15 watts.
As stated, look on Youtube for videos of people rebuilding a RBA or RDA to see what you're in for. Kayfun is a popular RBA, and TOBH is a popular RDA, if specifics help you find videos.
