Try it for the experience, if it interests you.
Radishes outside need to grow fast in fertile soil. Some potting mix comes with some level of fertilizer ( would say it on the bag) and most have no fertilizer included.
Whatever this does for you, if you enjoy the process, consider microgreens, or lettuce. The hydroponic 'local' lettuce I buy is about a dollar per ounce/ $16 per pound.
Sadly, I am having poor luck with indoor pot grown lettuce.
