If a Grobo is overheating, it will shut off the LED lights inside the grow chamber and then restart after a 'cool down' period. 



To help troubleshoot an overheating unit, please do the following:


  1. If the temperature in the room your unit is sitting in is on the hotter side, drain the Grobo completely and then move it immediately to a colder room - or - turning on climate control (i.e. A/C). Please see HERE for what temperature your Grobo's room should be.
  2. If the temperature in the room your unit is sitting in is not hot (i.e. Regularly managed by A/C), please conduct the workflow below. 


Check for Crossflow Fan Movement:


  1. Unplug the Grobo. Your plant will be just fine without lights for a bit.
  2. Remove the Carbon Filter.
  3. Plug the Grobo back into an outlet.
  4. From where you removed the Carbon Filter, look up inside and observe for fan movement. To be safe, do NOT put any fingers inside the fan's oscillating space. If you cannot look up inside the Carbon Filter's space yourself, alternatively, put your cellphone into Selfie Mode and record the space by holding the phone underneath it. Note what you observe.
  5. Going to the back of the unit, put your hand on the grating and feel for air flow. Do you feel anything? Note what you observe.
  6. If you do not feel any fan movement, please reach out to Customer Support immediately.
