Juice DIY

[Slinger]

I have read umpteen threads and just need to clarify something on mixing my own juice.
When i purchase ready made juice i might buy RY4 and it says 75% PG and 25% VG.

So after few months vaping i am ordering my own juices to mix.

This is what i will order..
38mg Base PG 100ml
100 ml PG
100ml VG
Strawberry Flavour to mix for example.

I want to mix a sample 5ml bottle of this @ 6mg stregth and like the ready made as above @ 75% PG and 25% VG.

So correct me if i'm wrong.

Base is 38mg
Target is 6mg
Flavour Strawberry @ 5%

According to eJuice calculator i need ....

17 drops 38 PG Base
53 drops PG (75%)
25 drops VG (25%)
5 drops flavour

=100 drops 5ml / 20 drops per ml

Will my resulting juice be 5ml Strawberry 6mg ,75% PG and 25% VG???

Here is a great calculator to use. I use it. eJuice Me Up - e-Juice e-Liquid Recipe Calculator
and by the way don't trust counting drops. There are supose to be 20 drops in a mil I tryed diferent dropers and liquids messured in 2 different gradguated cylenders and never got 20 drops to eaqual a mil.

Looks like it to me since most flavorings are in PG (though not all are) - depends on how you want to calculate it. It becomes more important when using more than 5% of flavoring.

53 + 17 + 5 =75 PG drops (if you include the flavoring as PG)
25 = 25 VG drops

How did you decide 5% for the flavoring - some flavoring need 10 or even 15 percent

I would first try 19 drops PG and 1 drop flavoring (5%) and see if that is enough flavoring

If it was indeed 20 drop/ml your numbers are correct. However, keep in mind that not all droppers yield 20 drops/ml. Also, be aware that different fluids may yield different drops/ml due to surface tension, viscosity, etc. I always use a graduated cylinder or syringes to measure liquids. For small amounts I use a 1 ml and a 3 ml syringe. The 1 ml syringe is graduated in .01 ml increments so you can do pretty precise measurements.

Agreed, I found my dropper bottles took 35 drops to make a ml.

I also agree that a graduated cylinder is a good idea. The type of dropper, viscosity of juice and even how hard you squeeze can really affect the number of drops per ml. That said, I typically find 30-35 drops to equal a ml. I typically measure the base in a graduated cylinder and then figure the flavoring drop by drop so I don't contaminate the cylinder with flavoring.

That's the calculator i used, great application.

Cheers,
My main query was to see if the way i was going about getting a 75%PG and 25%VG ratio in the mix correctly. My fear was that i would of also needed some VG nicotine base and mix that with the PG nicotine base first then proceed to mix.
I'm making this simple query very complicated but you answered it perfectly for me.

I won't be using drops as measurements, it was just for the benefit of my query.

Regards flavour percentage, i am buying from Inawera and it says add 3-5% for a particular flavour.
Was thinking of adding 1 drop of flavour for 1ml of juice ( 10 ml of juice-- 10 drops ( or maybe 12-15 )

Thanks for all the replies.
