These Red Arrow Radish microgreen seeds are bred explicitly for sprouting and microgreens. One of the more popular radishes in Japan. Use these microgreens to add zest to sushi, salads, and sandwiches. Especially Burgers!

Radish microgreens are quick to germinate, though the Red Arrow radishes are about a day behind other green leaf radishes but are vigorous growers once it gets going. They quickly reach 3- to 4-inches in height and are ready to harvest in 6- to 10-days.

Red Arrow Radish microgreens have medium-green to dark green leaves and are attractively lobed with pink to red stems.

Red Arrow Radish microgreens have a similar flavor to full-size radishes but a much milder spiciness and a pleasant earthiness flavor.

Radishes make the perfect edible garnish that will add a touch of color and spice to any dish. You can use radish microgreens in place of sliced radishes.

As mentioned, the flavor is spicy but not harsh.

Radishes are a staple microgreen because they grow quickly and easily and have excellent flavor and texture.

By Measuring Spoon

Home Microgreens Tray: 1.6 teaspoons

1010 Tray: 4.3 teaspoons

All volumetric measurements are level, not heaping spoons.

I use these vertical-sided measuring spoons because the seeds are easier to level with the straight sides.

These are my recommended seeding densities to produce a great-looking tray of Red Arrow microgreens.

I like to allow microgreen leaves to develop to a larger size as they provide more nutrition & flavor than producing smaller leaves and stems.

Microgreen density depends on many environmental factors and seed germination percentages.

You may prefer to modify the seeding density, but my seeding densities are a great starting point if nothing else.

Check out the Home Microgreens Seed Density Course if you have a different size tray.
