Juice has four core ingredients : Food grade Propylene Glycol, Vegetable Glycerin, nicotine and flavor. The nicotine is your base and comes either in PG or VG, your choice. The PG and VG you can get for about $10 a quart, if not the grocery store then Amazon.
I use the Vape Tool app to keep my recipes, though there are several other good ones. Makes it easier to calculate on the fly when changing batch sizes.
An array of 10ml, 5ml and 1ml(1cc) syringes are what I use for measuring. An example recipe to mix a single 30ml bottle at 3mg nicotine with 2% juice concentrate with a 60/40 PG/VG goes like this :
3% Base (liquid nicotine base starting at 100mg in VG)
.90ml
35% Vegetable Glycerin
10.50ml
55% Propylene Glycol
16.5ml
5% Thinner (distilled water, optional)
1.50ml
2% Flavor concentrate
.6ml
I mix them either into a wider mouth glass stopper bottle or into a tiny measuring cup (nice to verify volume at end), then use a final 10ml syringe to transfer into squeeze bottles. Keep one or two syringes for each ingredient so you don't cross contaminate, water wash-up at the end. The VG is syrup and a real pain to get in a narrow bottle, but once mixed it's not too bad. Cap the bottle, give it a good shake and it's ready to go. Let it steep for a week or two for best flavor development.
Some prefer to use graduated cylinders to measure, all personal preference there, just be careful with the 100mg concentrated nicotine. Wearing gloves while handling this stuff is a good practice, and store that somewhere safe since a kid or a pet would be in danger if they got to it.
Nicotine %, or none, is whatever you're used to. For my mod tank I use 3%, when I'm in an EVOD pen mood I use 18% since it produces so much less. $10 120ml nicotine base makes me a couple quarts of juice at that rate. I've been using Nude Nicotine and Vaper's Tech for my flavors and nicotine, though there are lots of others that have flavor concentrates and nic. Flavor % varies both by flavor and by maker of a particular flavor, they give a recommended % on the bottles. I never start with more than 2% even if they suggest higher - can always add more to your taste.
There are lots of videos on YouTube showing how others mix, I'd suggest watching a couple now that you have the overview to see what looks like the measuring process for you. Good luck and stay off burning leaves!
this mod is a dual battery and goes up to 200w however the tank can't handle more than 80w. The mod costs about $70 and the Tank is about $30
