I always advise, to start small, test after 24 hours, make adjustments, test again in 24 hours and so on, until its where YOU like it.
I started small with the LorAnn only because of information in the Wiki and I am glad I did. I have two other MCC Flavours here, that I use in between 10-20% and the LorAnn is 1-2%
The great thing about vaping and DIYing, there are always choices and LOTS of them available!
