I'm trying to sprout a seed mix for inclusion in salads, which is sometimes called "microgreens". According to my seed bag, I'm sprouting a mix of broccoli, radish, alfalfa and clover. I keep getting white fluffy mold on the sprouts, as shown in the photos below:
It occurs in both sprouting methods I use:
- A plastic tray with holes at the bottom to avoid stagnant water
- A jar with a steel-mesh top for drainage, where the steel-mesh top is downwards facing so it should be draining all the excess water
How do I prevent this mold? Am I watering the seeds too often? I leave them beside some potted plants, is it possible the mold is coming from there?
