Скачать или смотреть Mold on Sunflower Microgreens seeds. Find out if its mold or just root hair

Certain microgreens like amaranth have root hair on the roots to help uptake the nutrients. The root hair has a hairy fuzzy structure (not spider-web) and it is only on the roots so it is easy to detect if it's mold or just root hair. The mold makes your microgreens smelly (musty smell). The mold will generally be on small patch(es) while root hair will be throughout your tray.

If you are still confused if it is root hair or mold, just spray some water over it. If its root hair, it will disappear after the rinse, and come back in a few hours. If it does not disappear, its mold.

A combination of following things can build mold and fungi in microgreens:
Improper drainage or overwatering
Poor air circulation
Dark environment
High seed density leads to inefficient drainage and poor ventilation that leads to root rot. If the seeds are overlapping, the top seeds start to germinate, and the bottom seeds start to rot.
Mold loves humidity. If you have high humidity (more than 50%), the microgreens are going to get damp.
