I'm planning to start using a diluted fish emulsion for my pepper and onion seedlings, but I'm really concerned about the smell. They are currently growing in my kitchen, and I want to avoid any bad odors. How long does the smell usually stick around in the soil, and how strong is it when the emulsion is diluted?

From my experience, fish emulsion has a strong odor when used indoors. I tried it once and found it quite unpleasant. Plus, when I used it outside, it attracted local wildlife, like raccoons! I think you might want to hold off until you can move your plants outdoors.
I totally get the smell concern! I use fish emulsion indoors, but only in low concentrations—about 1 to 2 teaspoons per gallon of water—and it's generally not too noticeable, especially with my three litter boxes around to mask it! But if you're not comfortable, consider waiting until your seedlings are ready to go outside.
Using fish emulsion indoors isn't the best idea if you're worried about the smell. I'd suggest mixing it at about a quarter of the recommended strength, just to be safe. And if you have any spills, definitely clean out your drip tray to avoid lingering odors!
