My daughter gave me an aero garden and the light stopped working all of a sudden

Hello, thank you for using Howly. I’ll be happy to help you out! May I ask your name?

Nice to meet you, *****!
Have you tried any troubleshooting by yourself already, before contacting us?

Thank you for clarifying
Please, try the following:
Use the 'Lights' button to turn lights ON if they are not already on. Grow Lights must be ON to reset the light timer. Press and Hold the 'Lights' button for for 3-5 seconds until the control panel lights blink, then release.
