I just ran out of my 60/40 (pg/vg) DFW vapor juice that I normally use. I had half a bottle of 100%vg mod fuel juice that a friend gave me but it was 0mg nic. So I grabbed some of the nic from the freezer and did the calculations and put about 2ml of 100mg/ml of nicotine in and gave it a good shake. I am running just a regular coil in the Merlin with silica wick. Hopefully it works okay.
