VG will produce the lots of vapor, and has it's own, very mild sweet taste if the temp is right. PG add a throat hit and is often used to loosen up VG. Also PG brings out the taste of flavors generally much better than VG. Adding a small amount of distilled water will also loosen up VG and give a major TH depending on the amount added. You won't generally find fluids for sale with water in them since that opens up those companies to all sorts of regulations and controls. Hope this helps.
Hey thanks! That does help. Brings me to a new question too, what do you mean about distilled water? Im assuming you dont mean tap water then. Are you just boiling water? This may be a silly question, but where do you get distilled water from?
I have a fridge with one of those filter systems, is that good enough?
