So i just got my stuff for diy and im going to have my 1st go at mixing with a one shot concentrate. Never used a calculator before but does this look right to make 50ml with 7.2% nicotine at 3mg 70vg 30pg??
Just want to check before i mix it.
Drop it in a basin of hot water and give another good shake when hot.
It will look like that - lots of space in the bottle gives a good airy shake.
Then leave.
