Bot Shot Calculation

[Kieran Woodward]

I'm after some assistance with adjusting a calculation on one of my Bot Shots that I received in the post today as I have just found out that I have ordered 6mg instead of 3mg strength.

The bottle is to be 250ml of 70/30.

Instructions given with the bottle is to add;
20.8ml of 72mg VG Nic
24.2ml PG
175ml VG

What would I need to adjust to make it to 3mg strength using 18mg Nic?
What would I need to adjust to make it 0 Nic?

Yours Aye,

just a guess as ive never tried the big bottles before.

how much concentrate is in the big bottle @Kieran Woodward as that needs adding to the bottom left on the steam engine http://www.steam-engine.org/juice.html
usually concentrate are in pg so dont tick the vg box.

as long as you are using 100vg nic shots and once you add the concentrate the correct amount should be on the right.
this pic is without the concentrate so the readings on the right will be wrong until youve added to bottom left.

I think it is 30ml.

I get that by subtracting the quantities of VG, PG and 72 Nic from the 250ml total.

I'll have a look now I have that.

Thank you @MrDJ.

Even the quantities they have given you don't look correct to me . For a 70/30 mix a 250 total will need 175ml of vg. So adding vg nic shot's will make it wrong.

I see what they've done. The 175ml quantity they give includes the nicotine.
Check out the pic's below for 0mg and 3mg using 100% vg nic shot.

 

[Kieran Woodward]

Ah I get it. VG and Nic added together to make up the 175.

Still, that is poor instruction on their part. Written on the bottle also!

So am I right with the 0mg on the left and 3mg quantities on the right?

Roughly yes. See my above pics [emoji6]

There's nothing wrong with their instructions.

This is very simple - using 18mg nic and aiming for 3mg, your mix needs to be 1/6th nic, so 250/6 = 41.6666ml of nic. Call it 40 for simplicity, you'll never notice.

You have 25ml of flavouring in the bottle + 40 pg nic = 65ml. You need 75ml pg for a 70/30 mix so you add 10ml pg and top up with vg.

 

[Kieran Woodward]

This is the bottle.

The way I see it there us 175+20.8=195.8ml of VG in the bottle. With the remainder made up of PG.

Surely the ratio cannot be 70/30 then. Surely it's more 80/20
