Base Calculations (headache)

I’ve been toying with the idea I can make 70/30 bases, separate to 30ml bottles and add nicotine / extra VG later depending on what I want but want to double check something.

Base Size: 100ml
VG/PG: 70/30
Flavour: 20%
Nic: 0
Nic range: 0-6
Nic is VG based


If I separate the 100ml into 3 30ml bottles:

Example Weight:
30ml batch: 35.64grams

Note: These are all in Grams

To make 0mg from base:
Base: 32.49
Extra VG: 3.15
Nic: 0.00

EDITED
To make 3mg from base:
Base: 32.49
Extra VG: 1.58
Nic: 1.58

To make 6mg from base:
Base: 32.49
Extra VG: 0.00
Nic: 3.15

Would this work as I think or is there something im missing / not taking into account?

Holy Moly that’s brain freeze calculating for a Friday evening…the calcs add up to me and I can see how you’ve got the calcs to where they are…but totally await somebody with way more experience than me!

Shouldn’t the base at 3mg start at 32.48 since you are adding 1.58 grams extra VG and 1.58 grams Nicotine?
This so you end up with the same weight on all bases regardless if it has nicotine or not. As it is now you end up with 38.80 as a base weight on the 3 mg.

Yep, something went wrong there!! Thanks! BRB!

You are adding 3.16 grams right so the base should start at 32.48 as i wrote. If you only add 1.58 34.06 is accurate.

Done it, I was adding the extra VG rather than removing it :relaxed:

Thanks!!!

I knew what it should have been but getting the code to calculate it that way was confusing me (headache) lol

No problemo.

Will I end up with a 70/30 30ml doing it this way?

Any PROS / CONS to this method??

I would say no to that, only way you can maintain the 70/30 ratio is if that nicotine and extra liquid you add is a 70/30 mix.
I might be wrong and if i am i’m sure someone will chirp in and say so (but i don’t think i am).

The way I calculate the base is for up to 6mg VG based nic if i added the nic to the 100ml it would be:

100ml 70/30 6mg nic

The way I calculate the 3mg is to add the extra VG and then the Nic which would make it the 70/30 ?
Does that make sense?

Its pre-calculated using the recipe calc, im really not sure either now, wouldnt it have to be perfectly mixed to separate?

If I added the extras in the 100ml it would be fine right?

Ive started with the lowest denominator then worked up, you can put in but cant take out right?

All of it is a good reason for a ejuice calc

Then the final challenge is the end result. If you will mix between 0 and 6mg of nic. Build//mix your recipe with a plan of 3mg. That way when you mix at 3mg you are 100% correct and zero and 6% the variance/percentage of error will be smaller.

Also take into account working with 100mg nic vs 48mg. That percentage of error goes through the roof at 48mg vs 100mg.

You can make the percentage slightly smaller if working with max vg nic if you are going for max vg juices. Or with 30/70 to mix with and 30/70 nic base and so on.

You have to go to the lowest denominator, in this case 6mg nic has the least added VG so:

If I added the extra VG and then the nic for 3mg in the 100ml I would have 100ml of 70/30 3mg nic.
Likewise if I added the extra VG i would have 0mg nic 70/30.

If I separate the 100ml into 30ml’s will the 30mls be 70/30 after adding the extra ingredients or will they somehow alter?

10ml of a finished 30ml 70/30 is still 70/30 right?

Lol. I think you are over thinking.

My example is more for mixing up a finished product minus the nic.

As for pouring a bijilliion gallons of 30/70 and pulling out 30mls out at a time then custom making a end result with variables of high nic/low nic and different end goal for pg/vg ration is too much math. I’m sure it can be done.

I think the end result will require to much work. I know people have premade mixes of 20/80 pg/vg and by the time they add flavoring they hope to get a mix close to 30/70 or 40/60…but I am too anal about that. I don’t want close I want exact repeatable…

Tweaking a recipe 5 times later under that idea result in mixes being 50/50 40/60 35/65 and so on.

Thats not what im trying to achieve but I know what your saying, thanks

Lol. Words are still hard.

This is calculated per recipe not just overall if that helps, I have all the code done already just double checking :wink:

I’ll get a real example together tomorrow as it’s late here

This should help you pin point your numbers:)

Man you guys, I just check box “Max VG” ya’ll make my head hurt like I’m playing sudoku or something.
