I just got my orchid and its so close to a RDA but is a rba but what's the highest nicotine strength should i use on it. I know if dripping you can't go higher than 6mg but what about the orchid. Thanks
It is a personal preference. I prefer 3mg on both dripping and my orchid but can take 6 on both. I could probably take 9 on my orchid. I do notice that 6 is smoother on my orchid than my drippers by a considerable amount. Only way to know for sure though is to try your juice and see if it is doable. Just remember, you don't have to fill up the tank. You can try it as a dripper with a screw on top cap.
For me I like 7 mgs dripping but in tanks like the kayfun I prefer 18-24 mgs as these don't deliver that nicotine hit efficiently enough for me unless its high...
Since you can build it, saturate the wick, throw on the chimney and try it out, I would see how you do with the 18mg. If you can take 18mg on a kayfun, you may be able to on an orchid. If not, I would try 12 next.
