Yes, that's correct. But it would produce the same vapor as the pre made juice you vape now if the base is exactly the same as what you vape now unless you're vaping a blend of PG/VG. VG = more vapor, so conversely PG is less vapor. If you are looking for the least amount of vapor as possible, juice in 100% PG would be your best bet. You can buy that pre made. No offense, I think we're saying the same thing, but I'm not sure and your first question scared me. So, unless you are 100% sure you know what you're doing, just look for pre made juice that is 90% or 100% PG or and you'll have the lowest vapor production you can get.
