29 days — 'German Giant is a solid red colored,
round shaped, radish with crisp, white, and pungent flesh. It resists getting woody or spongy and can be harvested from golf ball size on up to about the size of a cue ball. To achieve the larger sized radishes, provide them ample space by thinning the seedlings to at least one-inch apart. Each packet contains three grams, which is approximately 200 seeds.
