How do you maintain your proper VG/PG ratio if you are making different recipes? Do all your recipes have the same exact amount of flavor and exact same amount of nicotine so your lines remain accurate to maintain proper ratio? What if your neighbor wants 60/40 and you vape 80/20? How do lines in a bottle work that way? Do you have every bottle marked? Wouldn't that take a bunch of time to measure out and put lines on each bottle so some how they don't get smudged off. I really don't understand how this could work and be accurate?
First, this is long, which is why I didn't post it on another discussion before, and asked people to PM me if they'd like to know about it. But, here's how I do it. Hopefully it'll answer your questions above. If it doesn't, just let me know.
Neighbor's eliquids are
all made so his finished ratio is 50PG/50VG and 3mg nic.
I use 100mg/mL nic base in 100%VG for all eliquids, his as well as my own.
I use flavorings that are 100%PG based, except for a couple from OSDIY that I like...which are 57%VG/43%PG based.
The below applies to the
eliquids made with 100%PG based flavorings.
I'll use the neighbor's finished PG/VG ratio and Nic mg to explain how I do it.
His finished 50mL bottles of eliquids contain:
50% PG ingredients = All flavorings + Plain PG
50% VG ingredients = Nic base + Plain VG
For making HIS eliquids...I have a line drawn on a 50mL "master" bottle at the 25mL mark (level for PG based ingredients), and another one at the 50mL mark (level
after VG based ingredients are added, too). I've put a piece of clear tape across those lines. I use
that master bottle and an extra fine tip permanent marker...to transfer those 2 lines (about 1/2" long) onto however many 50mL bottles he wants made during that mixing session. (It's simple to lay them down next to the master bottle that's marked and transfer the lines to them using a ruler. Takes maybe 5 seconds to mark each bottle.)
For
each recipe I'm making for him, I have the recipe card in front of its 50mL mixing bottle:
1. I draw out the flavorings (in PG) and squirt them into its respective 50mL bottle.
(If I'm making more than 1 eliquid for him, I do the flavorings for ALL the recipes first.)
2. Then pour/dispense the plain PG up to the bottom line on each 50mL bottle.
3. I draw out his nic base (in VG) and squirt it into each 50mL bottle.
4. Then pour/dispense the plain VG up to the top line on each 50mL bottle.
Done! Put the dropper tips in and the caps on each bottle.
Mine are done the
exact same way, except
my 50mL bottles will be marked (using the "master" bottle for my own 40PG/60VG ratio) at the 20mL level and the 50mL level.
He always wants 50mL bottles made. However, I make some 30mL, some 50mL, and sometimes even 100mL bottles for myself. So I have 1 master bottle for me...marked for 30mL batch on 1 side, and for a 50mL batch on the other side. Also have 1 100mL master bottle marked for me.
This method works for anyone's final PG/VG ratio and nic mg desired. Just last Thursday I met with another ECF member in Orlando, who vapes 70PG/30VG at 18mg nic, (using PG based flavorings, and 100%PG based nic)...to show her how I do it. I'd already marked "master" bottles for her, based on her PG/VG ratio, using PG based flavorings, and 100%PG based nic. She made 3 different recipes while we were there. Another ECF member who lives about 20 miles from me (vapes 20PG/80VG ratio and 3mg nic, uses PG based flavorings, and nic in 100% VG), is also using this method, instead of by weight, as he'd originally planned. He'd even already bought a scale, but now only uses it for weighing out portions of deer meat, etc. for deep freezer storage.
It may not be a method for everyone. But it works well for the people I've shown and/or told about it in person and/or in PMs, and for myself.
