Thanks for the details fourthrock......do you do tobacco?
Now that I have My Recipe (I don't do variety...I like menthol. Period) I generally mix and fill 60ml. bottles. I use the graduated cylinder to measure my PG (I just pour using a funnel and use the markings on the cylinder to get the correct mls. and the VG (use a large syringe with a VERY big bore needle) then measure my flavorings...using a 18gauge needle syringe or drops, depending on the amounts needed. Once that's done I measure my nicotine base in (I use a 48mg. base and only vape 5mg. so I only need 6mls.) I use a dropper for that. Once it's all measured out I pour it into my bottle. Drain the cylinder in there good. Cap and shake the bottle then let it steep in hot water (capped) until the water is cool. Put in dark cupboard. I find this to be efficient and I like that I can measure the PG (which I use at 85%) easily in it. I have a larger graduated cylinder if I want to make a 120ml. bottle. And a smaller one...which I'm not sure I'll be needing now that I've got the hang of things. It came with the set though.
