Why will this not work?

[xirokx]

Hi there

I am using 52mg unflavoured PG nicotine as a base

I want to make 24mg strength e liquid at a final mix of 70/30 PG/VG

I use e juice me up software when mixing liquids

Here is the result




Questions

- Can you see where the software suggests I should use 0.83ml of Plain PG? How can that be when the PG I use is mixed in with nicotine already?

- So what do I do with that 0.83ml of Plain PG it is suggesting? Should I add that figure to the recommended Plain VG to use instead? if not then what do I do?

- Should I use a stronger nicotine base instead? so stronger then 52mg base? to obtain a final receipe of 70/30 PG/VG at 24mg strength?

Thanks for your help

Try bumping down the "Percentage PV" in the results section until it doesn't request any un-nick'd PG. I think in the long-term you'll want to get some PG without nicotine to be able to brew the way you want to. If you have any kind of farm/ ranch store close by they'll have it. Other place do too, like some WalMarts.

It's telling you to add plain PG so you can get your 70% pg concentration (although I haven't checked the math). If you don't have plain PG go ahead and substitute VG- you won't have your 70/30 blend, but it will be diluted to the proper strength.

Here's your recipe in plain text:

52mg PG . . . 2.77mL . . . 46.17%
PG . . . . . . . 0.83mL . . . 13.83%
VG . . . . . . . 1.8mL . . . 30%
flavoring . . . . 0.6mL . . . 10%

If you add up everything except the VG, you'll find that it totals 4.2mL, which is 70% of 6mL (flavoring is counted as PG).

Edit: SuziesMom is correct. Add the 0.83mL plain PG (or substitute VG) to get the proper nic strength.

You should be able to obtain Propylene Glycol at a chemist shop.

You have to mix plain PG to bring your nic strength down to 24mg per ml. You can add the extra VG but then you won't be 70/30PG/VG, it would be 56.2/43.8 PG/VG... Your flavoring is PG based, so your figures show 46.17% nic + 13.83% PG = 60% PG, then add the 10% flavoring to make it 70% PG and the remaning VG 30% to give you total volume.

right, so I definately need to top up with plain PG? to get the final resulting reciepe at 24mg?

would I obtain 24mg if I added 0.83ml of plain VG instead?

What would happen if I added extra 0.83ml of PG with nic? would the final reciepe be stronger then 24mg?

Just wondering...

 

[Tasteles]

Yes it would be stronger than 24mg. If you top it up with VG, the 24mg would be the same but your final ratio would be 56.2/43.8 PG/VG.

thanks for your help guys

So I think the verdict is clear, buy some plain PG to obtain 24mg at 70/30

Cheers for that..

You can get PG at the Capella site.. 120ml for $3.95.. they also have the flavors on sale buy 4 get 2 free and shipping is pretty cheap too.. $3 I think.

If you plan on doing alot of diy, you can order USP grade PG on amazon or ebay. It costs about 25 shipped a gallon. If you have a large farm supply store nearby they sell it too. Its used to treat ketosis in cattle, and will be near the medications for animals. It sounds like alot to buy at once, but its worth it and it will last you a good while.

thanks guys

I bought some plain PG and I can see its well worth it because now I make 60/40 - 65/35 and even 70/30 final receipe juice at 24mg

It removes the harshness and edge compared to what I was doing before i.e. adding drops of flavouring because I initially bought the wrong base..

Cheers
