Radish Microgreen Growing Kit: Harvest spicy, peppery radish microgreens in only 10 days. Ideal for adding a vibrant crunch to salads, sandwiches, or as a garnish. Planting: Radish seeds are slightly larger. Scatter them evenly but not too densely, as they grow quickly and need space. Germination: Radish seeds germinate rapidly, often within 1–2 days. Ensure the medium stays moist but not waterlogged. Growing: They grow fast and thrive with direct bright light or under grow lights. Harvesting: Typically ready in 5–10 days. They have a crisp texture and a spicy kick, excellent for garnishes.
