For those using cotton. How often do you change it? Or maybe the question should be when do you know it needs changed? The way this KFL is working I'm thinking of retiring my rba and building my KFL with the nano kit for Sludge. Dang First one KFL now two and I'm thinking of getting number three. This forum is a bad influence.
I use cotton in my drippers and they dont last but a couple mls because in a dripper it gets low on juice and the cotton burns. In the KFL you ought to get a tank at least if you're vaping HHV. Some of these nasty NETs I like it wont last even a tank.
