wow! I'm new at this too and it's soo refreshing to hear how far you have come in so little time. Keep going strong!!!
Yeah I'm stoked. I can't believe my friends actually want to buy my liquids. I was just making them to make them. But they like my mix, so I'm cool with that. It will pay for all the supplies and trial and errors I did. Honestly, it isn't that hard, you just have to be cautious when handling the nicotine based liquid (I prefer PG over VG nic base, as many forum goers say the nicotine mixes better with the PG than the VG.
I am college educated, but totally not a chemist or anything like that. My degree is in compute engineering, but honestly, with all the help in the forums, and thousands of recipes for mix out there published on all types of websites, I found it pretty easy, and you should to. If you just want to experiment, you can buy in a smaller quantity, like 120ml of PG nic base and maybe 120ml of PG and VG and some flavoring and go from there. Just be sure to read a lot first, and then use the calculators out there. You don't even really need the bottles, you COULD put them straight into one of your tanks, but from what I'm reading here lately, steeping makes your liquids taste better.
Steeping is the process of storing your freshly made e-liquid in a dark place for a few days, basically letting it sit. With PG/VG, it can take a few days for the flavoring to mix properly and blend with all the other compounds in the mix. You ever notice that your liquid from the same bottle tasted a little different a few days later than when you first received it?
Also, if you liquids are nicotine based, store them in the shade or dark, and keep them out of the sun. I see friends often put their bottles in their car, in the cup holder or something. Nicotine reacts to direct sunlight and will darken over time in the sun and also destroy some of the compound of the nicotine (from what I'm reading). So don't store your liquids in hot places, or leave in your car.
