I have noticed since I started diy that with my own juice I am gettin way more vapor production! Not sure why this is - I mix up 30ml unflavored base @ 65pg/35vg then mix 5ml flavored batches. I'm doing this because I like to switch flavors a lot! Reason I am going 65/35 is because all my flavors are pg based so I'm shooting for closer to a 60/30 final mix. But I'm finding way more vapor compared to premade juice! Has any one else found this? Its not a bad thing imo!
