Ok, I'm trying to do math, which is normally fairly easy for me, but just isn't working today. OF course, I *should* leave this for a day when my brain is actually working, but I'm bored.

Given 18mg +1 65/35 juice and a bottle of 100% VG.

I want to both up the VG amounts in it and cut the nic level.

I know the flavor will take a hit both from adding VG and from the fact that I'm lowering the percentage of flavoring by just adding VG.

What I'm trying to figure out is a calculation that will let me figure out what the nic level will end up at for various amounts of added VG.

I've got the math working for unflavored juice - but I'm missing something when I add in the flavoring percentages. Do I treat the flavor percentage as a completely separate piece of the calculation?

Been playing with a couple of online calculators, as well, but they really don't seem to be set up for this. Therefore, spreadsheet.

If you are already working with a premixed it could take a significant amount of VG to make a serious dent in the Nic percentage, how much are you lookin' to drop it?

Not much - no more than down to 15. It's really the pg/vg ratio I want to change some. I'm learning that I need higher VG in the winter, and particularly when I'm living on decongestants and anithistimines.

It may be that this is a stupid attempt, and I'd be better off just ordering flavorings. But I decided to play with vv before I stock up on DIY stuff, so this is intended to be my "cheat". :)

(Aka - the funds I'd set aside for DIY materials just got spent on a new pv. :) )

5ml of VG will drop a 30ml bottle of 18mg to 15.4mg theoretically ;)

ok so, say you had 20 mill of 18mg/ml juice in a 30 mill bottle. You decided it was too strong and needed some VG so you dumped 10 mil of vg in. What do you now have?

20x18=360 - 360 is the total mg of nic and that will not change because you are not adding nic.

You added 10 mil of VG for a total of 30 mils of fluid now.

360/30=12mg/ml

Hypothetically of course.

Well, had my first failed DIY. Not exactly sure what I did, but I'm expecting an oversight while mixing. I whipped up 50ml of Double RY4 (TFA) and it was haaaarsh. One puff and I coughed. My better half tried it and said it was 'peppery' and 'tingled' in her mouth. I think I may have not been paying attention and added too much nicotine solution. It ended up going down the sink. Not too terribly upset about it, but lesson definitely learned. PAY ATTENTION WHEN DOING ALCHEMY! :p

Opal, I feel your pain. Math is so cold and unflinching. Nothing bores me more than math. Except maybe soap operas.

Yup, even with an established procedure which allows me to deal with interruptions...

No distractions while mixin'! ;)

I seriously think that was what I did. It was a bit less harsh this morning, but I could feel the nicotine flooding my system. My base was only 36mg, but still, when you vape 4mg, that's quite a leap. I thought perhaps I added PG, but that would not account for the taste that accompanied the harsh. I can tell if there's more than a smidge of PG anymore as I only vape VG, but it's nothing like what I was tasting and feeling with that batch. At least I have a ton of the Double RY4 left, it's becoming a fast favorite.

Aw, c'mon. Math is a good thing. It's just a language. No need to be afraid of it!

I'm just shortening the learning curve on how nic, pg, vg, and flavorings interact by asking questions. There's a great post over in the DIY forum with the basic formula, but I'm not operating at full capacity here, and while I get the concept, I'm not applying it properly right now.


ok so, say you had 20 mill of 18mg/ml juice in a 30 mill bottle. You decided it was too strong and needed some VG so you dumped 10 mil of vg in. What do you now have?

20x18=360 - 360 is the total mg of nic and that will not change because you are not adding nic.

You added 10 mil of VG for a total of 30 mils of fluid now.

360/30=12mg/ml

Hypothetically of course.

Got it. But how does that adjust the pg/vg ratio?


I'm assuming that I'd have to do something like this:

100ml of juice at 65/35, including flavoring, would have 65 ml of PG (partially from the nic mix, and partially from the flavoring, assuming PG based flavoring) and 35 ml of VG. This seems like a false assumption to me, because I'm assuming that the flavoring itself would take away a certain number of ml of the PG. How much, however, I don't know.

So - if you add in 10 ml of VG, you now have 110 ml of juice - 65 ml of PG and 45 ml of VG.

45/110 = 41% VG - so that would now be a 59/41 pg/vg ratio, if I have the math right, correct?
