i am new to making my own liquid and i did my 1st lot yesterday and i we to VRU shop and told them what i was doing and that it was my 1st time doing this and they give me 1ltr of VG 5 60ml bottles and i got 2 30ml concentrates. is that right though no PG they said i dont need it useing a dripper
I've had a quick look at this and worked out it could work if you're mixing your concentrate at 10%, not adding any nicotine and are happy with a final ratio of 90% VG and 10% PG
(270ml of VG mixed with 30ml of flavour concentrate)
I've never tried juice with that ratio and tend to make mine 80% VG and 20% PG with more flavour concentrate (I've found VRU concentrates weak)
If you want to try an 80% VG 20% PG mix this can be done by using 20% of your flavour concentrate and no additional PG will be needed
(120ml of VG mixed with 30ml of flavour concentrate)
I'd try making up 10ml of each and try them to see which you prefer.
9ml VG mixed with 1ml of flavour concentrate = 90% VG 10% PG at 10% flavouring.
8.5ml VG mixed with 1.5ml of flavour concentrate = 85% VG 15% PG at 15% flavouring.
8ml VG mixed with 2ml of flavour concentrate = 80% VG 20% PG at 20% flavouring.
Hope this helps and my apologies if I've over complicated things.
