I am trying to get into DIY and I want to use natural flavors rather than artificial flavors. Are there any vendors that have natural flavors or do I have to extract them myself? Also, pretty much how this works is mix your desired amount of flavors into a base liquid and get it all to the desired ratios, right? Is there stuff other than flavors to add? I don't want lots of throat hit, I like VG more than PG I'll probably do about a 70VG/30PG end ratio. Thanks guys!
