I am going to use 100% VG juice. I have read where in many instances the juice does not wic as well due to it being thicker. I saw somewhere, really can't remember where now, that you could add maybe 2 or 3 drops of vodka maybe to 20 or 30ml of juice to water it down. I am not saying I know this works, I am saying I do not know. Does anyone know if this is possible. I would not think it would be dangerous as this small amount would not make it flammable.
