No need to apologize- we are all here learning IMO. I've DIY approx. 9000 ml juice.
"Generally" pre made juices are 70/ 30 PG/ VG or 80/ 20 PG/ VG
PG= TH, Lung Hit and flavor enhancer
VG= vapor
Nicotine= TH, Lung Hit and our need for nic.
If someone wants more VG then because it's thick and doesn't flow properly some will add a small amount of PGA, vodka or distilled water. Some say these give a TH while others say it adds harshness and is not nice- don't know as I've never used them.
My mixes started out at the above #'s and that's what I mix for friends but, for myself, I now mix a 60/ 40 PG/ VG and add in extra flavor because I enjoy the vapor but also the flavor.
So from what I understand you're mixing flavors + nic PG based juice?
My nic juice is PG based as it's easier to work with than VG based nic. Are you using a calculator?
When I order the juice they ask... "Base PG or VG", so I always choose PG then like I stated on topic 24/28mg strength.
Now I'm real confused as thought PG was a mix base as was the VG but VG from my reading was supposed to be thicker. Not understanding the chemistry obviously behind the making of the juice - sorry.
