Radishes are a salad favorite, and boy do they grow quickly--about 20 to 25 days. Our seed packs contain around 300 seeds. Radishes are very versatile; you can use them for sprouts or micro greens. They can grow in the cold; just keep water on 'em in the heat. You can replant every week or two. All our varieties are Non-GMO and Heirloom. Get a few packs to plant, water, repeat! Happy growing!!!
