Cut # 2 in half as well. I use 3% for my main flavors. I have never gone with suggested %'s. I can see it being alone as a single flavor. You very well could be a low percentage user like myself. I would suggest using no more than 3% for the main flavor if your going into complex mixtures. I have a blueberry muffing mix that is 11 different flavors with a total of only 9.1% total flavoring. Kind of looking at this whole thing as a cook would. Less most of the time equals more. You should just be able to make out the flavor that you want when you mix the flavors together. Then you let it steep a day or 3, week, 2 weeks depending on the flavor. Here are a few Great reads for DIY: starting out with this snippet from one of them that made the lightbulb go on above my head after reading. "Disclaimer: Hoosier's DIY blogs are to only be read and understood by folks who have read all the sticky's in
DIY E-Liquid and are based off of my experience with mixing my own juice for over a year.
Hoosier's levels of flavoring from too little to too much:
- Nothing (Did I forget to add the flavoring?)
- Something Odd (This does not taste like the flavor I put in there.)
- I Can Taste Something Kinda' Like It (I can detect the higher or spice notes, but not the actual taste)
- Hooo, It's There, but Real Light (Getting close now, let it steep before adding any more)
- Bingo (Duh, we have a juice)
- Hmmmm, That Is Close, But Has A "Je Ne Sais Pas" of Oddness (Dang didn't let it steep and I overshot)
- Kinda' Close, but the Perfumey/Chemically Kills It (Going into the too much realm here and may be due to ignoring the steep part of #4.)
- Whoo, Did I Forget to Put the Flavoring In? (Too much flavoring can actually make things impossible to taste.)
Note that the first tier and last tier are much alike, the only difference is the way the unvaped juice smells. If it smells fairly close, but has no flavor then it is usually too much. (Usually, not always as there are exceptions.)
Steeping means leaving the capped bottle out of sun light for a period of time to allow time for the components time to reach an entropic state. If you think steeping is something else, or don't know what an entropic state is, please talk to someone else about your issues. I have a closed mind on steeping and have not taught basic physics since my freshman classes when the professor gave up trying to counter my arguements and left the class to me.
