you can buy pure grain alcohol in small quantities to not having "laying around" the house.
although i don't drink, (maybe once a year) i just bought a pint of PGA which i will use almost all of it to soak the tobacco. surely once you add the tobacco and chuck the bottle in the trash you're not going to be tempted to drink the PGA infused with tobacco!
pga just eliminates the long steep times and also produces a much much cleaner eliquid that doesn't gunk up your attys as much.
personally, i've never done a NET with just PG.. has anyone done both and compared the results?

I believe an ECF member called 'str8tvision' has done both. Maybe even a PG/ PGA hybrid extraction ? Check with him....
Ive done the PGA and VG extracts separately with the same tobacco as a test, the VG extract was very dark and gunky as compared to the PGA ....
I just separated the tobacco and solvent from a 9 month cold PG extraction started back in early March. The PG had turned thicker than VG so I added 15% ethanol to thin it down for filtering. I extracted Sutliff "VooDoo Queen" a tobacco blend I'm well familiar with and often use as a control for experiments. I mixed up a ml using 20% extract and sampled it. The higher flavor notes are absent and much of the tobaccos complexity is muddled but the heavy, deep raw tobacco taste was frightening. After just three pulls It literally left a tobacco taste in my mouth like I had just smoked a full Cuban cigar....*cough cough* Strong doesn't really do justice in describing the flavor, it's quite intense. Perhaps 12% would be better but I'd bet it's going to be a heavy gunker. *cough cough* 
Conclusion: For cold PG based extractions, 9 months might be a little too long of a soak.... So far 90 days is my preferred soak time.

Blobofblubber mentioned earlier in the thread that 10 weeks was about optimal for him, now Str8tvision says 90 days (or 13 weeks) is his preferred soak time. Sounds like 10- 13 weeks is optimal for results from cold maceration.
Thanks to Everyone. Merry Christmas and Happy New Year to All !

I might be talking to myself here, but at least it's recorded for later comparison
I'm listening - keep going
OK, same gear and same technique for sampling as noted earlier;
1) Sutliff Voodoo Queen - Same 'burnt soap' taste as Stokkebye's English Luxury, only not as pungent. This selection may actual blend nicely after filtration and considerable aging.
2) Decatur Black Cherry - mild to moderate tobacco with just a touch of black cherry topping. A decent vape, hopefully the top note doesn't disappear with aging.
3) Newminster #24 Imperial Nougat - moderate tobacco flavor highlighted by a delightful chocolate/ vanilla flavoring. While the tobacco isn't the finest, it isn't garbage either. This flavor could go either way with aging, depending on the tobacco.
That would be samples of all twelve of the NET's I am trying. The third week of January should mark the tenth week of steeping, I will try filtration at that time.
Oh, and I mixed another 3ml each of H&H Louisiana Red and Orlik Golden Sliced, just so I could vape them on Christmas Day
Merry Christmas Everyone !

I just returned home after an extended contracting trip, one that got extended a few times. Hidden behind a bunch of stuff on a book shelf is a jar of what I think is Organic American Spirit in PG. It has been sitting there for almost 10 months! Both curious and afraid to try this.....
If not too strong/robust it might actually taste pretty good. Just remember, if you REALLY like the flavor of a 10 month extraction it'll take nearly a year to reproduce it.
Eight weeks and I can't wait any longer.... started filtering them down. Hopefully by the end of the weekend I will have all twelve done.
A little advice, please - first, the Lab Nerd paper filters I am using do not have a 'micron' rating. Called the manufacturer and they didn't know what I was asking. But it takes about 1 1/2 - 2 hours for 100ml to pass through the filters by gravity feed.
Just curious - if I were to heat the extract in a crock pot on low for a few hours, would I be able to speed up the filtration time ?

Not familiar with those filters but if it's passing through that quick , I would say the rating is pretty high. I'm assuming a 100% pg extract? The 2.5 Ahlstrom filters I'm using takes about 24 hours for a 100-120mlx100% pg of extract @ room temp. to pass through. The Thomas 1.5 filters take 30+ hours to filter. My first ethanol extracts passed through 1.5 micron filter in under 3 hrs. Have not tried heating and filtering together. Hopes this helps.
Yes, warm PG based extract will filter considerably faster than cold extract. If it's too cool, PG doesn't filter well at all. Unfortunately, even if you warm the PG it will likely cool back to room temperature before it all filters through, it's best to raise the ambient (room), temperature above 80F. I've done this using my oven, turning it on just long enough to warm the interior to around 120F then turning it off and filtering the extract inside. I would leave the oven's interior light on to help keep it warm, >80F.
Even heated >80F, 100 ml of PG would've required over 16 hours to filter through the Ahlstrom 2 micron cellulose filter paper I used back then. If the filters you're using did it in 2 hours at room temperature (70F), their retention rating might be well above 5 microns.

If you got off a pretty clean/clear extract after filtering, I'd pull off some and mix it up for aging and a test run. Should be OK. How did it look after filtering?
I agree with USR, go ahead and try it as is. If it's too gunky just get a different filter and re-filter it, won't hurt a thing.
When I poured the extract into the funnel/ second filter, there was a blackish ash-like silt in the bottom of the jar. Started on third (thickest) filter this morning...
The presence of silt indicates the first filter's retention level was woefully inadequate. Hopefully the thicker filter will catch/remove the particulates.
