OK, back on topic again.
The calculator
eJuice Recipe Calculator
can be used to do the 50/50 thingy also.
Enter the strength of the NIC juice, like 35mg/ml VtVapor unflavored (VG based, already has water in it, but no need to complicate the calculation)
Then the desired strength, like maybe some medium 15mg/ml (sorry Generic),
Then about 10% more water,
Then about 5% flavor, like maybe Loranns Cinnamon.
The results are:
21.4ml of NIC juice (VG based),
21.1ml of no NIC juice (use PG),
5ml water (distilled please),
2.5ml (about 2/3 of the 1 dram bottle of Loranns)
You get 50ml of 15mg/ml of what I would call 50/50 PG/VG
Even if you rounded off to 20ml of NIC Juice, 20ml of PG, 5ml water, 3.7ml (whole bottle of Loranns) you would be close. (a little less than 50ml of 14.4mg/ml juice). Won't cure the morning Jones', but I'd vape it later in the day. Heck, try it and if your don't like it start your own "Pot Luck" bottle.
