PG VG Query
ii would like to try to make a mix of 70VG/30PG or maybe 60VG/40PG

having done some research i believe im right in saying that with my current ingredients its impossible



my Nic is 72% in PG

my flavours are PG based

i use 20% flavours and make 18 MG 



so if i make 10 ml of 18 mg am i right in thinking that 55VG/45PG is nearest i can get as below



NIC BASE 2.5

FLAVOUR 2

PG NIL

VG 5.5

------------------------

TOTAL 10



i have 360 ml of my nic base so im stuck with that base.

is it feasable to buy some VG base and mix the 2 or is that going to be complicated

RE: PG VG Query
You can get nic in VG - personally I prefer this. 

Everything Liquid do it and Darkstar do it (Those are the two cheapest I know of in the UK)

You could mix VG base with PG base - probably more hassle than it is worth.


Your sums are correct - this is something I saw very rarely when I taught maths and science thirty years ago.

I find the easiest way to work out nic is to work out the total amount.


So 100ml of 18mg/ml liquid contains 1800mg of nicotine.


(BTW, the nicotine content is 7.2% not 72% I hope. If it is 720mg/ml then whoever sold it to you committed a crime by not checking your Poisons Licence.)

We have 72mg/ml nicotine so we need 1800/72 ml of nicotine solution which is 25ml.

Thank you for your answer, which has helped. And I am sorry for mix up re; % and mg.

I take it i am right in thinking that if I mix the following i would end up with a 50/50 base

100 ml 72 mg  VG
100 ml 72 mg  PG
--------------------
200 ml 72 mg 50/50 VG/PG    or is there a variable I an missing. as mixing these two amounts should be to big a problem.
many thanks for your help

RE: PG VG Query
That's right. Most flavours are in PG and around 20% flavour works for me.

So you'd do better with 70%VG in the base - so 140ml of VG nic and 60ml of PG nic. 

When this base is used with 20% flavour we get:

2ml flavour 0/100
2.5ml nic 70/30
which gives you 1.75ml of VG and 2.75ml of PG.

So add 2.25ml of PG and 3.25ml of VG to get 10ml of 50:50.

As your nicotine level drops, the small amount of nicotine used means less PG added so it becomes immaterial whether your nic is in PG or VG. 

Below 5mg/ml I use PG base as it makes little difference to the PG/VG ratio. I do this for the 4mg/ml juice I mostly use in drippers as it is still above 80% VG which is the sort of juice I prefer.

RE: PG VG Query
I no longer mix my own juices. I came across a 250 ml bottle of VG that's about 3/4 full. I hate to waste. If you can use it, PM me and I will get it to you. My treat.

ROCK ON! VAPE ON! Music2
