cheers

Any chance you mean "PG", rather than "AG"?

VG, or Gycerin USP/EP/BP, is the pharmaceutical grade glycerin we use for eliquids. You get more vapor, but generally less transmission of flavors, and some perceive less throat hit.

It's pretty common to bump the flavor % up for VG mixing. It's also pretty common to thin it a bit, preferably with a bit of pure grain alcohol (I use a 160 proof plain vodka, strongest I can easily get locally), though distilled water (available in a supermarket) can also be used.

Some people are sensitive to PG, need to use little or none of it. Similarly some people are sensitive to VG. In my cae I get a slight "heaviness" if vaping very high VG mixe, though only noticeable when doing things like running.

I haven't heard of AG. I use VG, nicotine and distilled water in my juice, no PG or flavorings.

thanks for the replies i use Pg/Ag dilutents Ag being Aqueous glycerin from tw, i think its thinner than Vg, its pre watered down, but everybody here seems to use vg

Regular glycerin is as I described previously -- thick, clear, excellent vapor production.

thanks markfm some good information in your post, i am assuming theres not too much difference, i find using Pg/Ag carries flav well and vapour and th are both good, do get a kind of dull headache if im vaping hard, is that what you mean by heaviness?? yzer is your nic pg based, i never really get the mixing percentages, are people talking percentages for dilutent only or the mix as a whole if your nic/flav is pg based, sorry have taken this off topic already

That makes sense. Glycerin USP is 99.5% anhydrous glycerin. It is a thick, viscous liquid. I heat it to 100-110 degrees F to make it flow easier for measuring and mixing. Glycerin USP needs to be thinned with something like water, alcohol or PG before it is thin enough to work in carto fillers or atomizer wicks. The nice thing about Glycerin USP is that will have an expiration date of up to five years if the container seal remains intact.

My understanding is that Aqueous glycerine is just VG with deionized water to make it thinner. You can do the same with regular VG and Vodka, PGA or Deionized water yourself.

I buy 100 mg nicotine in VG base. I mix that base with Glycerin USP to 25 mg and store it in the freezer in glass lab bottles. I use that 25 mg base to mix the finished e-liquid later when I want smaller batches in 30 ml dropper bottles. I add the distilled water during the final mixing.

The final percentages for the mix I use are measued by volume. I don't include the volume of nicotine is the mix as it is so small that it doesn't matter. Instead, I describe the nicotine as mg per ml of liquid. 95/5 means 95% Glycerin USP and 5% distilled water by volume. I don't consider the .5 to .3% water in Glycerin USP itself in this formula because that amount of water is insignificant.

The heaviness I get from high VG is in the lungs, not horrible but it's just harder to move; I only get this doing intense aerobics, but have chosen to normally vape no higher than about 50% VG, unless it's testing something that I have made for another person.

A headached from vaping hard -- maybe slightly too much nic? I would drop from my normal 24 down to 12 for chain vaping. (Now I'm at 10 mg/ml, use it all around)

Say you have an eliquid which is 80% PG, had about 12% total flavoring by volume (1.2 ml of flavoring in 10 ml of final eliquid). If you now switch to, say, 80% VG, you might find that the flavoring needs to be bumped up a bit, to say 15% total.

The % are a hassle at times. I generally just go for the dominant %, and that's what I label the bottle with. For instance, if I am using a 100% PG nic base, I'll count all the ml of nic base towards my PG % (don't sweat the little bit that's actually the nic). Likewise if my flavorings are all nominally PG, then those ml all count towards the PG %, I don't sweat the fraction of the flavorings that is the actual flavoring content.

The "outliers" are when I am making something special, for people who are sensitive to either PG or VG, those bottles get labeled as "0PG" or "0VG". In those cases I have made sure that my flavorings have no PG (or VG). I personally don't like to call something 100%PG or 100%VG because those are incorrect in anything I make -- there's always some % of nic, flavorings, and often alcohol in organic flavorings.

I inhale my 95/5 VG/H2O juice sometimes as inhaling VG is much easier and smoother for me than inhaling PG. I hold vapor in the mouth and throat and exhale slowly through the nose most of the time. I still get plenty of nicotine that way.

thanks a lot for all of your help, some really good advice and it looks like i have some experimenting to do. Think i have been mixing slightly wrong, i cant wait to make a new batch im using a nova 2.8ohm, ego twist @ 4.6v, might try vg/alcohol next, ps dont try exhaling through the nose with a pg mix i think i just singed my nose hairs off

P.S how do i pm a mod

sorry just realised, ipad probs

I can't do a high VG content because of the COPD I have. It's hard for me to find the right mixture of PG/VG. Best I've had is a 70PPG/30VG. If to high a VG I have to start my breathing treatments again. (only had 7 or 8 since last september. Use to be 2-3 times a day).

sorry to hear that tnt56 but glad to hear your getting better, did you read yzers post above, may help you out

The PG is in my breathing treatments. Ive tried all sorts of ratios, and the 70/30 seams to work the best. The VG gives me a really heavy lung feeling.
