GR8 I dont think you are correct when you state above to set your target nic level to zero because her nicotine is already 18. That is not how the calculator works. The target nicotine is set to what MG/L of nicotine you want your batch to be. When you put in the nic strength, the calculator knows how many MG/L of the nic to add depending upon how big a batch is being prepared. For example you might want a 24 Nic strength and by using a 18 strength nic you will just have to add more nic to reach 24. You always put a target nic of whatever you want your end batch to be. If you put a zero target because your nic liquid is 18 the calculator is not going to calculate the batch ingredients properly.
You have failed to read the original post. I have been doing this a little while, and one of the things I learned early on is to simply pay attention to detail. Oh yeah and reading, not just scanning when you are inferring that someone else doesn't know what they are doing, and feel compelled to post such publicly.
Let's see if I can make it simple for you.......
The original poster purchased over 200ml of premixed 50/50 PG/VG 18mg nicotine.
That's premixed to a proportion of 50/50 18mg nicotine liquid. Meaning 50% Propylene Glycol 50% Vegetable Glycerin at a strength of 18mg.
Are you understanding that?
Pre-mixed
UNFLAVORED 18 mg nicotine suspension in 50/50 PG/VG.
In a quantity of 215ml.
Next hint, original poster stated that... oh NUTS.....
here read this:
I bought a 215ml bottle of 18mg nicotine with 50pg/50vg base mixed in bottle.I also have my flavors being shipped as we speak!
OP is just adding flavors to a preset nicotine suspension 50/50 18mg.
Capisce ?
