Using premixed base when mixing

[gabos]

Hi folks,

Going to order stuff to make e-juice soon but I have a question about using premixed bases.
I intended to buy seperate VG and PG bottles so that I could make 70/30 mixes. Doing this works fine using online recipe calculators.

But I also came across a 70/30 premixed base. If I would use this base in my recipe, what would I have to change? Let's say I use 4% flavoring (as recommended for this particular flavor) in a 50ML bottle. Do I just top it off with the premixed base or do I have to re-calculate?

EDIT: The flavor's I'm using are PG based.
also 0 nic.

I use a pre mixed base. I usually add one or two flavors to that, or sometime just 'vape the base'.

4% flavor added to 50ml base is 2ml so the difference in pg/vg ratio is negligible. I just starting pre mixing my own nic bases and notice no difference in taste or nic satisfaction.

Not too sure of what you are asking.
"I intended to buy seperate VG and PG bottles"
Might want to use the following calculator and fill in the blanks with your flavor(s), nic, VG/PG requirements (The calc. will tell you how much VG and PG to add to fulfill your requirement).

"But I also came across a 70/30 premixed base."
You can use the premix VG/PG. The calculator will give you the results above using separate amounts of VG and PG.
Example reading the calculator "Calculate" button: answer for a 70/30 VG/PG addition -----------------> VG 3 ml. and PG 1 ml. (which equals a total of 4 ml.VG/PG).
You would then take your premixed 70/30 VG/PG and measure out 4 ml. to add to your flavor(s) and nic.

If you put 2ml (4%) flavoring in your 50ml bottle and topped it off with 48ml of 30PG/70VG base, you would end up with a finished ratio of 33PG/67VG. (Actually 32.8/67.2).

IMO, this discrepancy from your desired ratio of 30/70 is not enough to make a noticeable difference.
