Hi, I have been mixing my own juices for about 9 months and have just ordered a pre mix base 40pg/60vg having previously bought pg and vg seperately. When using an e juice calculator am I right in assuming that I add together the pg and vg base totals together? e.g the calculator states 10ml pg and 8ml vg so I would add 18ml of the pre mix base. Apologies if a stupid question but just wanted confirmation. Stay safe everyone during the current Corona Virus outbreak.
