I know you can order VG, PG and Nic separately but Mt. Baker sells a liquid that is premixed to your specifications and I'm starting with a 50/50 18mg solution. I ordered an 8 oz bottle, a number of flavors and a sweetener. I know this is going to save me a lot of money, as long as I don't screw stuff up and have to end up trashing any batches. I'm pretty confident that I can calculate the correct mls equal to the percentagese with the base and the flavor and I am planning to just pick up an oral syringe for measuring them. Given that the base solution is premixed, this should be a fairly simple process for a DIY first timer. Are there any tips anyone wants to throw my way?
