What is that white fuzz near the roots?

Microgreens often show a white fuzz near their radicles, known as root hairs or fibrous roots. These usually appear within 2-3 days after the microgreens are planted and have a soft, cotton-like appearance. With a diameter of 5 to 17 micrometers and a length of 80 micrometers to 1.5 millimeters, they are particularly small and delicate, but serve to increase the root surface area and improve soil penetration. Their main task is to absorb water and nutrients and pass them on to the plants, which supports the natural growth process. Their presence is therefore a sign that the germination process is proceeding successfully and that the plants are being supplied with everything they need to grow. The shape of the root hairs varies depending on the microgreens variety.
