Since it's a recurring question , here's a way to work it out the traditional way:
Operating system : The grey matter between your ears
Hardware : A scrap of paper, a pen, handful of braincells, a pocket calculator
Pre-requisites : Read the stickies regarding DIY
AAQ ( i.e. Always Asked Questions )
Find answers first i: ( The answers are examples so that you're able to tag along )
How much juice do I want to make ? - 20 ml
How much nicotine do I want in my juice ? - 6mg/ml
What ratio of PG / VG do I want - 40 % PG , 60 % VG
Now take your scrap of paper, run a line down the middle.
The left column you name PG , the right column you name VG
40% of 20 ml ( 20 x 0.4 ) = 8 ml
Write 8.0 at the bottom of the column named PG.
60% of 20 ml ( 20 x 0.6 ) = 12 ml
Write 12.0 at the bottom of the column named VG.
Lets start with the nicotine base :
USA , most common base is 100 mg per ml
Europe it's anywhere from 72 mg/ml down to 36 mg/ml.
Check the label on your nic base : It should tell you the nicotine content AND whether the nicotine is dissolved in PG, VG, or even a mix of both ...
As we want 6mg /ml our 20 ml bottle will need a total of ( 20 x 6 ) = 120 mg of nicotine in it.
Let's say your nicbase is PG with 100 mg /ml :
120 ( your desired total ) divided by 100 ( mg/ml ) = 1.2 ml.
You need 1.2 ml of your nic base.
As it is PG, enter 1.2 ml in the PG column.
If your nicbase happens to be VG, then of course you would have to enter the 1.2 ml ( quantity of nicotine hasn't changed ) in the VG column.
Flavours next :
Again, check labels
By far the most flavours come dissolved in PG.
Very few come dissolved in water or ethanol ( aka drinkable alcohol ).
Steer clear of flavours dissolved in vegetable oil. The may be fine for cooking or baking, but aren't meant to be vaped.
After you done some checking an musing you decide on 8% for Flavour A .
Flavour A comes dissolved in PG.
The total of 20 ml needs to get flavoured ( 20ml x 0.08 ) = 1.6 ml needed of Flavour A.
Note 1.6 ml in the PG column.
Flavor B comes dissolved in PG as well.
To round our our recipe, we need let's say 3 % of Flavour B
The total --- 20 ml x 0.03 = 0.6 ml of flavour B go into the bottle.
Write down 1.6 ml in the PG column.
Guess we're done ... now lets tally up the columns.
PG:
Nicbase 1.2 ml
Flavour A 1.6 ml
Flavour B 0.6 ml
Total : 3.4 ml
As we need 8 ml PG in the bottle we top up with ( 8.0 - minus 3.4 ml already allocated ) 4.6 ml unflavoured/nicfree PG.
Our VG column is blank safe for the total VG we calculated right at the beginning.
Thus, 12 ml VG go into the bottle.
With me so far ?
Good. Then you surely remember to put a cap on the bottle before you start shaking it
If not....start reading from the top .
Hope this helps some of you
