Gloop ratio

[icepie]

Sorry if this has been done to death but I can't find the answer I'm looking for.

Is there a rule of thumb for mixing a particular PG/VG ratio for a particular power or resistance? All the calculators I have seen either assume a standard ratio or require you to input a ratio. What I'm looking for would be something along the lines of you input the Watts/Ohms and the calculator works out the ratio, or maybe just a general %VG per Watt, something like that.

To clarify... if I'm using say a 0.3 coil at 30W, how much VG do I need, how much for the same coil at 50W and so on, or the other way round if my mix is 60/40 how much power can I use?

I get that higher resistance = more PG for example, but is there a definitive relationship between the electrics and the recipe?

No, higher VG content will need better wicking, that's all.
Watts used depends on user, airflow, taste, possibly your build (or stock coil) but not the juice.

As @mannikon says - there is no relationship at all between the wattage / resistance and PG/VG ratio...
I vape 50/50 in pretty much everything, but I've also vaped 100% VG on 1.5 Ohm coils. PG/VG ratios are mostly decided by wicking - tiny holes don't wick thick juices and huge holes could get gurgly with very thin ones, Flavour and clouds are also a factor - high PG carries flavours better and gives more throat hit while high VH is smoother and gives denser more visible vapour...

The only time I've ever really noticed the need for thinner juice is when I used to Mouth-to-lung vape. That required a thinner juice (60pg/40vg)

Since started sub ohm (long ago) I use 70vg or 80vg. Even tried 100vg.

Wattage makes no difference at all. It's all down to wicking if you use RBA/RDA.

Thanks for those replies guys. Seems I have been somewhat misinformed. According to the guy at VHQ, thin liquid gets scorched at high power and thick liquids don't work in high resistance coils. (I don't build my own... yet)

If there's no relationship, then I can just get on with experimenting. From what Chris has said I think I'm still going to need a few different mixes as I use stealthy MTL in public and cloud-chasing DTL at home.

If it was me mate, I'd try a 60vg/40pg juice. I found I could use that liquid in both MTL and DTL.

Right OK - I see where he was coming from, It's sort of right but for the wrong reasons, most of the thinner juices are used in MTL devices (with small wick holes) that simply are not designed for higher powers - they have very small wicks so if you turn the power up you vapourise the juice faster than the wick can transport it - result? dry hits, same with the thicker juices - they just dont wick well in things with small wick holes and tiny little wicks...
