Hi, I am currently facing a problem i dont know how to fix. When my 2 fans turn on at night to cool my growth rack, the temperature rises from 20 degrees celcius to 21.7, why is it rising? If anything, shouldnt it be dropping? This is even when my air conditioner is turned on at 19 degrees celcius. Has anyone experience this before?

Presuming your fans are blowing in the correct direction there are only two options that come to mind.
1. The airflow brings along the heat of your lights to your measuring point.
2. The fans themselves produce heat as they turn.

To find out: take a handheld meter to take temperatures at several points including near the fans, inside, outside etc.

Hi, thanks for the reply. I figured out the problem, it is the outside air the fan is suctioning in is hotter than the interior of the rack. I just gotta find out how to fix that, thanks for the reply.
