Hi, everybody! I wanted to revisit this thread to share my findings over the last 6 months of gathering only PG-FREE concentrates and extracts. If you are looking to mix without PG for any reason, this is a peak at my stash. Mostly RF, NF and MF, which are easy to find and high quality.
I’ve read lots of ideas on thinning VG if needed, and while they are all good ideas to explore and experiment with, I’ve found that any of my recipes can be flipped to PG-free by simply omitting the PG in the calculator(I like to add 10-15% PG for mine, omit PG completely for my wife). Hand-shake for a minute or two to blend, shake a few times during the steep. Let it steep for 2-4 weeks, or more if you’d like. 4(+) weeks is best. This has worked with 1-2% total flavoring(MF recipes) as well as 8-12% total flavoring.
I realize there are are lots of opinions on this that may challenge mine, but this works really well for me. If you’re using a low wattage, small, screw-in and go, coil head like the old eGo tanks, you might need to look into thinning the VG, but sub ohm tanks like the Arctic and Cleito have no trouble wicking high VG at all, and any RDA, RTA or RDTA definitely work wonderfully.
I hope this can help anyone with a sensitivity to PG. Happy mixing, everybody!
