Yes! The light on the Instafarm™ is typically on 24/7, however, if you would like to have the light off during a particular time of the day, a quick press of the power button will put it into Night Mode. During Night Mode the plants will still be watered but the light will remain off for 10 hours, after which it will automatically turn back on. The indicator light is blue when the Instafarm is in Night Mode. You may quick-press the button at any time to exit Night Mode, turning the lights back on.
