Base pg vg guidence please

Hi all

A bit if a little dilemma here need some pro advice pretty please

So i got myself some pg/vg base already mixed up at a 30pg / 70 vg ratio thinking it would make my life alot easier

My problem is That base is 30/70 but by the time i add my nic and flavors its messed the ratios up ???
My maths is crap to say the least but i understand that pg nic and pg concentrates are going to end up making this more like 39/61 :frowning:

I have some additional vg and pg bottles that i can add in but for the life in me can not figure it out at all please can anyone give me some guidence. I wont be buying a pg vg base again lol

My overall plan was to mix up a big base of pg/vg 30/70 and 3% nic at 500ml then i can draw from this to make smaller bottles with concentrate in

Thanks in advance

I suppose you could just add 10% of VG to your PG/VG mix to get it to 20/80, then after adding your flavours and nicotine you will be around 30/70 again.
Take out 50 ml of your 500 ml PG/VG and add 50 ml of VG to it, that will up your VG with 10%. I wouldn’t add the nicotine to that base if I were you because after adding the flavours you will not be at 3% anymore. I suggest you make your 500 ml base and add the nicotine to the little bottles at the same time you add the flavours.

The math is actually pretty easy. When you create a recipe the calculator will tell you how much pg/vg to add. This of course is also dependent upon you entering your nicotine base and how much of that is PG and VG.

So, look at this recipe which is for 30/70 PG//VG

Since the recipe is compete, you’ll see that the amount of PG and VG to be added (dilutants) are shown in ml, Drops and %. Let’s just worry about ml.

With 30/70 pg/vg blend, that means for every 1 ml of pg there will be 2.33 ml of vg

Since there is 5.98 ml of PG called for, then take 5.98 x 2.33 = 13.93. That tells you that when you add the amount of your 30/70 blend to get the needed 5.98 you will have also added 13.93 ml of vg. So 5.98 + 13.93 = 19.91 total of the 30/70 mix. You add that. But you’ll see that it called for a total of 20.62 ml of vg. So 20.62 - 19.91 means you only need to add .71ml to make it exactly 30/70 for the total recipe. In this situation you might think why bother, if it’s that close I’ll be fine. But the recipe I just used as an example was @Shaner Chewy Spicy Sugar Cookie and it is over 8% flavoring, which is counted as PG. So the amount of VG added may be small here, but will fluctuate depending on how much flavoring is used.
