Mixing help needed

[greendollar]

I have a bottle of Frogsters WLT & Liquorice at 18 mg and want to make it up to 28 mg but I'm unsure exactly what quantities to add to achieve this ??? .....I have 75mg nic base , tobacco concentrate & liquorice flavour but need some help

I can't help with the maths, as I'm carp at this GD, so I'll leave that to the mathematically enabled.

But, what size bottle of ready mix is it you have?

[greendollar]

30 ml Perps

You could make up some 38mg/ml e-liquid using your base and flavours, then combine the two in equal proportions. (38mg/ml+18mg/ml)/2 = 28mg/ml

Thank you PMS I'll get on it tomorrow

I am interested in this too as there may be a time when I have to do the same thing and I don't want to sound thick and I understand the maths I.E 38+18 divided by 2= 28. but surely if you add 38+18=56 by combining the two together and shake the bottle really well, well surely no matter how many times you split the bottle, wouldn't you still have 56mg and obviously smaller ml per bottle or am I being thick.

[greendollar]

lol , no not being thick infact a good question but i think it's a combination of PG/VG nic base & flavouring that 'waters' down the nic level to the desired level when you put the two together ......or perhaps I'm being thick

There are not 18mg of nic in the first bottle but 18mg/ml
i.e. in a 30ml bottle 18mg/ml X 30ml = 540mg nic and in the add mix 38ml/mg X 30ml = 1140mg nic.

Combining gives a total nic content of 540mg + 1140 mg =1680mg nic and a combined volume of 60ml.

This is 1680mg/60ml = 28mg/ml

Ah I see you multiply the mg to ml to get the volume. On which I forgot to do, in fact it didn't even occur to me. I always had a feeling but I now know for sure as I stand in the dunces corner.

Thanks for explaining Dave and good luck Greendollar
