Purple rain in purple tent

Hello my friend, if the tent is hot already then the only thing that can help is airconditioning. But it is better to prevent the heat in the first place. You can turn the lights on during the colder hours of the day so at night. This way you keep a more stable climate between night and day. The second option is to extract the air from above the lamp and get an inlet from a colder place in or outside the house.
