It's my own recipe.. my son's g/f vapes about 20ml a week of the stuff and... I would like to make a 100 ml bottle of the stuff - so I can get some peace . OK the 1 drop ingredient - (lime) will be easy - 5 drops. But there are some ingredients that have 12 drops, 8 drops etc and I am going to lose count or the will to live if I have to add it via drops and not a syringeSorry I don't know what the recipe states, but if it states one drop, it would all depend on the size of the creators drip.
