I'm a newbie so maybe I shouldn't already be working on DIY, but I'm a flavor Junkie and I already love to create my own flavor blends for tea etc, so ive ordered my nic base and PG and VG, installed an ejuice calculator app on my phone and read a bunch about it, now I'm concerned that I dont know how much flavor I should start with since some flavors are more highly concentrated than others.... some people say 10% other say 30%, some say 30% of dilutes etc, I imagine it all must greatly depend on the manufacturer. could someone who has some experience with using flavors from natures flavors help me out and give me some recommendations on the amount of flavoring to start with? I am especially excited about creating my own lychee pear juice... juicy vapor's tribute rocks my socks off!
