I was also wondering, Is it worth it to spend the money on the supplies if i dont know that I will enjoy the flavors I make?
Start out simple with the basic ingredients and one or two flavors you KNOW you will like. Most vendors use flavorings from any of just a handful of flavor companies. MUCH more information in the DIY eliquid section...
Try this for learning how to "cut juice":
I quit smoking a week before my wife did. She still likes more nicotine than I do... She prefers 24mg, I typically prefer 16-18, maybe a *little* stronger if I'm going out and can't vape any time I like. We both like a couple of the same juice. We save money on these by buying a bigger bottle, usually at 36mg, and with plenty of extra flavor shots...
She prefers a 65/35 pg-vg blend, I like 50/50. We buy our extra strong, extra flavored juice usually in 80-20. I bought a bottle of pure PG and a bottle of pure VG (236ml each) and a bunch of empty bottles. A little math, a little trial and error, and both of us are happy... on one bottle of juice
Now to make things even more interesting I recently got into mechanical mods and super low ohm vaping (0.7-1.1 ohms). A quirk of this sort of vaping is that the vapor production can be so huge that a few puffs of 18mg juice makes my head spin! So I take some of the juice I already cut down to 18mg and then cut it *again* by half, usually with VG, sometimes with a bit of PG too, and I put that in another bottle... 9mg of nicotine, just for "sub-ohm" vaping! The flavor is muted a bit but because the vapor production is so huge it still tastes great!
And that's how one bottle of 36mg, 80/20 pg-vg juice gets transformed into three smaller bottles... one 24mg @ 65/35, one 18mg @ 50/50, and one bottle of 9mg@around 30/70!
Sooner or later I suppose I should learn to DIY from scratch
