Adding VG to premixed juice

[raccus]

I noticed that I am very sensitive to PG. I have a bunch of 30ML premixed 50/50 bottles that I would like to dilute to 70/30 by using VG. Can somebody please help me with the calculations to do this?

3 parts of your juice to 2 parts of VG. nic will be reduced to 2/3rds

Nothing wrong with Adding pure VG to a Pre-Made e-Liquids to Raise the VG Percentage.

But Understand that when you Add Anything to a Pre-Made e-liquid that does Not Have Nicotine in it, you are going to Lower the Nicotine mg/ml level.

Also, adding Pure VG to a Pre-Made Flavored e-liquid is going to Reduce the Flavor.

If you want to keep the Same mg/ml level, and if you want to keep the Same Flavor Strength, then the Best way to do it would be to Add the Same Flavor and the Same mg/ml level in 100% VG to a 50:50 e-Liquid.

50/50 = 50% PG, 50% VG
50% = .5

.5 * 30ml = 15ml PG, 15ml VG

Problem: how much VG should we add, so that the resulting mixture is .7 VG, .3 PG?

Since we're only adding VG, the amount of PG stays the same, at 15ml. So the question can be rephrased as "15ml is equal to 30% of how much?" Now, it's a simple "solve for x" type equation:

15 = .3 * x
.3 * x = 15
x * .3 = 15
x = 15 / .3
x = 50

...so the total amount of liquid should be 50ml. That means we need to add 20, to our original 30. Let's check the result:

15ml + 20ml = 35ml VG.
15ml PG has not changed.

15/50 = .3 or 30% PG
35/50 = .7 or 70% VG

The resulting mix is 30% PG, 70% VG.

Right On bwh79

I like when people Do the Math and Show their Steps.

This is exactly what I was looking for. You broke it down perfectly to help me get a better understanding of the math. Thank you!!!
The above procedure is calculated by adding VG to the existing 30ML. What if I wanted to stay at 30ML?

Target: 30ml, 30% PG / 70% VG

30% of 30ml is how much?
x = .3 * 30
x = 9

We're then looking for 9ml of PG in 30ml of liquid.

Start with 18ml 50/50 (9ml PG, 9ml VG) and add enough VG (12ml) to make 30ml total.

Check:
9+12 = 21ml VG
21/30 = .7 or 70% VG

9ml PG
9/30 = .3 or 30% PG

Thank you bwh79-I've been trying to figure out the formula as I want to go from 50pg-50vg 24ml nic to less pg and less nic. I was using some online juice calculators it was giving me errors.

Start with 18ml 50/50 (9ml PG, 9ml VG) and add enough VG (12ml) to make 30ml total.

Check:
9+12 = 21ml VG
21/30 = .7 or 70% VG

9ml PG
9/30 = .3 or 30% PG

Thank you again! It makes a lot more sense now when it's broken down like that!

I'm not quite sure I understand what you are saying. If you are at 30mL already and it is 50/50 and you dont want to go above 30mL, you can't add any VG without getting rid of some of what is already in the bottle. If that is what you are talking about, I will try to be of some help. At the for 30mL of 70vg/30pg, you want 21mL VG and 9mL PG. You currently have 15mL of VG and 15mL of PG in the bottle. If you want to get that down, you are going to have to take out 12mL overall(that will remove 6mL of PG and 6mL of VG, leaving you with 18ml, consisting of 9mL each of VG and PG), and then add 12mL of your pure VG.

Keep in mind, this is going to reduce the amount of flavor by 40%, since only 60% of the mix will be juice that was previously flavored.
