I usually buy my diy vape mix premade 50/50 ratio at target nicotine level.I am trying to cut back on some costs ,and make an unflavored base mix to have on hand .My plan is to buy a 24 nicotine strength bottle of PG base ,and a bottle of Vg .My question is if I mix equal parts of the 24 strength nicotine pg to equal parts of the vg, does that make my base 12 mg nicotine strength .I appreciate any help ,thanks.
