It is recommend to use Go-Ferm nutrient in conjunction with Fermaid K or Fermaid O for yeast rehydration. Technical data sheets for each are below along with some quick guides. Why do you want to use both? Using an analogy… you’re car racing on an oval track and use plain gas (Go-Ferm) for the first half of the race. You’re doing good but you want a little boost to improve performance so you can win big! At the pit stop, you add octane booster (Fermaid) to your fuel and it gave you the extra boost you needed to get that big win.
