I buy liquids with 100% PG at either 18mg or 24mg nicotine strength. Then I mix up my own liquid in a separate empty bottle, adding some of the liquid I've bought (like RY4 and Green Apple for example, the same amount of each), and then I'll add VG to equal about the same amount of the RY4 and Green Apple combined. I use Glycerin that I bought at Wal-Mart (found on the shelf above the rubbing alcohol). I usually end up with somewhere between 40 and 50% Glycerin and 60 to 50% of the RY4 and Green Apple (that both contain 100% PG).
Example: 4mL RY4, 4mL Green Apple, 5.5mL Glycerin, when using 18mg nicotine strength. If the nicotine strength is 24mg, I would add 8mL of Glycerin. Then my final nicotine strength is 12mg, which is more than the Merit Ultra Light 100s I used to smoke, but it seems to be the best throat hits and taste for me.
I just started vaping on September 14th, and this is what I've found works best for me now, but I know I could easily make changes in the future.
