Hi @r0gue z0mbie. I have found that steeping does improve the flavour of the juice. I can't really say if there is a major difference between a week and two weeks but I know after a week there is a more rounded deeper flavour than vaping just after mixing. For some flavours a longer steep time...
@Derick I have found that the passion fruit also doesn't agree with the polycarbonate tanks. After vaping a few mls I find it creates a white film on the inside of the tank. Doesn't do this in glass tanks though
And always keep notes of your recipes if you inventing new combinations. It's so easy to vape on something after a week and think "this is awsome " only to then have the thought "my god I can't remember the percentages"
Hahaha @BumbleBee I don't usually use 12mg, after a year of vaping I've tapered down by nic considerably. But yes this thing does hit hard. I want to try a store bought juice and compare the flavour production coz right now I'm vaping DIY juice so can't comment on flavour production but can...
