Properly disinfect trays before growing.

For hydropoinc without any medium, tilt the white net tray about 45 degress for about 1 minute to drain out the water on the tray after each spray.
Control the humidity of the growing space.
Control the temperature of the growing space, too warm may cause the mold grow agressively.
Provide good air circulation in the growing space.
Presoak the seeds with eco enzyme, ratio for eco enzyme to water is 1:500.
Add eco enzyme or 3% food grade hydrogen peroxide into spray water, ratio for eco enzyme or 3% food grade hydrogen peroxide to water is 1:1000.
Avoid seeding too densely.
Set up proper lighting conditions for 6-10 hours daily.
Remove the seeds with mold immediately, prevent the mold to spread out.
