mixing

i have 5mls of witches brew that is pg
i have 100mg pg nic base
how do i mix it ?
would normally get me juice 70/30 db and mix me nic base with vg to a 70/30 mix and mix together 50/50
witches drew was free with me order and wont to try it .at 12mg

 

To acheive a 12mg juice 70/30 mix the following;

1.2ml nicotine 100mg pg
0.8ml PG
3.0ml VG
5.0ml doubler.

You haven't specified what mg nic you want so I used a 12mg sample.

 

Without knowing your target nic strength, it's impossible to answer your question.

 

12mg and if i have 3mls witches drew as i just lost 2mls over the bench

 

It's called witches brew. I gave you 12mg above. What a fluke lol

 

Revised for 3ml doubler;

0.72ml nic pg
0.48ml PG
1.8ml VG
3ml witches brew not drew.

 

thanks for help

 

half asleep dammit

 

Think I will be posting on this thread for a while to come yet. I still try the mixing sites but I'm still not confident enough to trust myself. I am doing mostly premix stuff at the moment and if it gets a little hard on the throat, I just add a bit of no nic VG which does the trick. When I really get into dyi, I might camp here. *sets up tent*

 

DiY isn't as hard as it is made out to be, although some members here would have you believe it is
Consider mixing a doubler with unflavored nic, that is essentially all DiY is & in it's concept actually is basic DiY.
Now for proper DiY, you take that a step further, you are sill adding 50% unflavored nic, the same as you would with a doubler but instead of adding the flavor, PG & VG in one shot, you need to add these 3 components separately.
Lets look at the easy ones, PG & VG, these are hard to get wrong VG more so than PG if you are using a PG based flavorless nic. If your nic is 100% PG base & you know what ratio of VG you prefer in your juice, then the VG component is easy to work out.
Lets say you like 30% VG in your juice, the unflavored nic is 100% PG based so then the rest of the components added to the nic need to total 30% VG, well this is really simple, lets look at a 10ml bottle.
5ml will be unflavored nic, if using a doubler to make your juice, we can also use the same amount when doing real DiY, so the base is 100% PG, that gives us a starting ratio of 50% PG, since the other 50% is unknown at this point.
We know we want a 30% final VG ratio, so to get that, we add 3ml of VG, you now have a 50/30/20 PG/VG/unknown ratio, so the VG is the correct ratio to your preference.

Next you add your flavor to your preferred taste, lets say you like a 10% flavor strength. So now your mix is 50/30/10/10, 50% PG, 30% VG, 10% flavor, 10% unknown.
Now lets look at that unknown & make it known, anything after flavor is going to be added PG, using this method, so unknown (10%) is actually PG(+10%) so now the ratio is 60% PG, 30% VG, 10% flavor.
Time to revisit flavor, most flavor concentrates are made using PG as the base, some use water, some use alcohol & even fewer use VG as the base , some use a combination of all 4 or any 2 of the 4 bases. For our purposes, since PG is the most widely used concentrate base & since alc & water thin the juice(much like PG does) & since VG is rarely used as a flavor concentrate's base, we count the flavor as PG in the final ratio of our juice.
So now what we have is a 70/30 PG/VG juice that has 10% flavor & is at the same strength as a juice mixed 50/50 with a doubler & unflavored nic.

So what are the advantages of using concentrates if you can achieve the same results using doublers, you may ask?
Good question, for a start it is usually cheaper to mix your own juice from the basic components used in all juices, those being flavor, PG, VG, nic, those are the main ingredients of all vaping juices.
The next advantage, which is probably of more importance than the first, is you can tailor the juice to your own tastes, lets look at the 10% flavor we mixed above. If that flavor was too strong we could add more unflavored nic, PG & VG to get the nic strength the same & the PG/VG ratio the same with less flavor. Now if the juice was too weak we could add more concentrated flavor, more unflavored nic & more VG to get the same nic, PG/VG ratio & stronger flavor from our juice.
The third advantage is knowing what has gone into your juice, there is no secret ingredients that you don't know about, which means if you are allergic to a particular flavor concentrate(s), you know it won't be in your juice.
There are more benefits but I see the above 3 as being 3 of the best advantages to DiY mixing.

All DiY juice is essentially the same as mixing unflavored nic & a doubler or trippler, there is just a couple more steps to it, it is nothing to be scared of

 

Nice rundown there Noe.

I keep it really simple and pre-mix my PG/VG to the ratio I'd buy a doubler at in a separate bottle,then pump in the deets into here eJuice Recipe Calculator

I use the No-Fuss Syringe Tek to bring the No-Nic plus flavour concentrate up to 5 ml and the rest is 5ml Nic.

Using 100%PG base and strong good quality concentrates that are not diluted to the crapper with VG or PG as they don't bloody state what the base is from some places.

I think HC actually uses VG as it's thick.

Done

WOOT!

Hit the Millennial Mark

 

I've found the easiest way to do the maths is by working out how much nic I want in the final volume of juice.
For example, if I want 5mL of juice in the bottle at 12%, I need 12mg x 5, which is 60mg.
If my nic strength is 100mg/mL, then I will need .6 mL nicotine liquid.
For some reason, it's easier for me to work backwards like that, and it's easy to check at the end visually, that I have done the maths correctly.
No matter how good the calculators are out there, there's still the chance of user error when you input the numbers. I prefer to be sure that I can verify it myself rather than to rely on a calculator.
I always check my numbers with MrGruffy too, be.comse when you're working with 100mg/mL nicotine, you really don't want to make a big boo boo.

 

Good to see the lateral thought mrsgruffy!

It's the same methods I used to get through maths at school,man the arse about way the curriculum dictated was meant to be confusing I reckon.

 

When you are mixing larger volumes, a few drops here, a meniscus there or the overhead of the syringe are no worry, but in such small amounts with such strong base those kind of errors become more relevant - mix well and stay safe abl86!

 

mathsguy thanks i c wot u mean norm i would ps i didnt endup mixing the witches brew in the end for that reason

 

To make it a little easier on yourself to mix, at the expense of a small reduction in nic strength I would amend the above amounts to this:
0.70ml nic pg
0.50ml PG
1.8ml VG
3ml witches brew

You could then add 1 drop more of nic if you wanted to to get the nic strength almost perfect.
