There are two sets of fans in your Grobo:
- Exhaust Fan
- Intake Fans
The Exhaust Fan help cool down your Grobo. There are a lot of LED lights inside the Grobo and this fan helps get rid of some of the heat to allow proper temperature control for your plant. This is located inside your Grobo at the top.
The Intake Fans bring in new, fresh air for you plant. Proper circulation and airflow are needed to keep your plant growing. These fans are located at the bottom, back panel of your Grobo.
Remove any debris or blockages that could be obstructing airflow to either fan.
