Hand watering Microgreens – No system attached

  • Fill sprayer with ONLY cold tap water below the MAX line and close cap tightly
  • Pump the air pump as much as needed
  • Inspect the solid white garden tray for standing water
  • Dump out the standing water (if any) to avoid molding
  • Remove the humidity dome (if any) from garden tray
  • Spray until growth medium is saturated (approx 10 sec)
  • Spray the inside of the humidity dome lid
  • Replace the dome lid carefully to avoid splashing large drops to seed/plant
  • If mold is visible: spray with hydrogen peroxide in dilution (1 : 5 = 30% H202 : H20 ) using the spray bottle. (Make sure you see bubbles form on the mold, that will indicate if the peroxide concentration is strong enough)
  • If seeds have sprouted (are showing baby leaves) then move the tray into another position in the light.
  • Update database accordingly.
