Had a thought yesterday, I may have missed it being talked about in the last 150 pages, if this is a repeat question please forgive me. While steeping using either the heat or UC, would it be a faster steep time using either straight VG or PG? Then once that is steeped you would complete your VG/PG ratio mixing afterwords?
When I first moved from the little gas station e-cigs to a clearomizer a few years ago the availability of e-juice and shops selling it were limited and I could not find a juice that didn't have a solvent taste and was vapable so I went to
vaping an unflavored mix of 75% PG - 25% VG. It wasn't until six months ago when I found a local shop that lets you sample juice that I started
vaping flavors again and for me they are all too strong. I cut all my flavored juice with the unflavored mix at 1/3 flavored to 2/3 unflavored, shake it up and vap it right away, steeping my cuts does not improve the flavor at all. To my surprise, cutting the flavors by 2/3 doesn't really reduce the flavor drastically, maybe by 40-50%. I also get a lot more bang for my buck on the store bought flavors.
While I was cutting a new bottle of Uncle Junk's Jon Wayne last night the light bulb lit and I started to wonder if steeping in straight PG would be quicker because it's thinner.
