When making a starter with White Labs yeast does adding a yeast fuel (AHS term for yeast nutrient) add that much to the starter to justify the purchase?
I use Fermax in all of my starters. You can buy a half pound of it for $7ish, and you only need half a teaspoon in a starter and/or 1 tsp/gallon in your boil. The result is healthier yeast, so I think of it as a small extra price to pay for higher quality and less chance of a stuck fermentation.
