I use 100% vg nic. And most of my mixes are close to 95% vg unless I cant find the flavor in vg base or I cant naturally extract it using vg. If you do cut it I can give some advice, I use a couple diff. Products to cut for diff. Reasons.
Distilled water- I use distilled water since it has no minerals in it and minerals will cause a build up on coils, not to mention fluoride and other additional chemicals not in distilled water. Water does nothing for me but thin out the vg for help with tanks but not to big a deal for dripper. 5-10% used on average.
Pga (pure grain alcohol)/vodka/moonshine- these are normally distilled more than once and the smoother the drink the better it works, it also adds throat hit but I dont use it for that honestly. it can help with mixing of flavors and when steeping it can evaporate leaving the thinning aspect to best less then perfect. 5-15%
Concentrated lemon/lime juice- I tend to use this as a thinner plus a smoother to add complexity to fruit flavors. I also mix it with water/pga to help achieve what im after, I normally use around 2-10% and that depends on the fruit flavors used.
Vinegar/apple cidar vinegar/balsamic- this is a smoother and always mixed with water or alcohol for use in tobacco flavors, its always used in 1-5% and i only use when making tobacco flavor as when adding heat it will take ions and helps to keep the ph more balanced. Which is odd and you would think you want to add a acid that will smooth the higher pg but it does not work as well imho as opposed to the acv in small amounts.
Saline solution- I have used before but never found my sweet spot but it can help turn an acidic fruit into a smoother mix I have heard.1-10% was average from what I remember.
Smooth- I have used it many times with tobacco juices and it works well but it is odd because to much destroys a juice and too little will do next to nothing imho, tfa vape wizard I have heard is similar to it also.
Using things like em or other sweeteners mixed in low percents mixed with distilled water/acv/pga can help smooth it out without adding much of any sweetness and thin out juice.
Tfa has some non pg/non vg flavors and base that is reported to be great for cutting or thinning juice while carrying flavor great, the downfall being it can seperate from vg and can also cloud/crystallize in the vg/pg mix.
There are some other options you csn use on the market also. I can tell you what I have found from my experience, vg/pg/nicotine are all nuetral in ph. When using lemon juice it is used in such a low amount it has very little effect. The same goes for vinegar but acv has an ability to receive ions when heated since its carbon molecules, its been sometime since chemistry so I could be slightly off in my wording. Much like their affect on tobacco and fruits when added its a way to smooth very tart flavors are by using coffee flavor, I use 1-5 drops of diff. Coffee flavors to smooth the super tart flavors, to understand why add a tbsp of expresso to a strawberry or lemon shake and enjoy.
I have reached my limit on this message so far but will add more when I get time lol, hope this helps someone.
