Thanks for all the advice guys, I can always count on this site to be helpful.
I know this mixing lark is going to save me money, eventually, but like everything to do with vaping it's so hard to stop spending!
started off with a starter kit from makemyvape, then discovered I'll need a dripper for testing, so went on to gearbest to get one. Decided I might as well get myself a new mod and a new tank whilst I'm on there!
After my first run of making half a dozen juices using syringes, had a look around and decided mixing by weight is the way to go, so have ordered some digital scales as well.
Wish I'd discovered the e-liquid calculator site before i bought another 20 flavours from chefs flavours, only discovered it when i was looking for info on how much % i should be using for single flavours.
Luckily the flavours I did buy seem to be some of the most popular, so I have good base to build on.
Just waiting on my scales to come now, can't be arsed to mess around with syringes again.
