Hey so I have a 4x4 grow tent in my closet with a full spectrum 250 watts and my grow tent temp is 85 I’m running a carbon filter a clip fan and another fan how can I get the temp down
Are the plants starting to smell already? If not the filter isn't necessary and you could increase airflow by using the fan disconnected from the filter for now with a little modification. Possible to snap a photo of the setup might help others give you some more advice. Good luck!
Inline fans are primarily for air exchange. If that alone isn't bringing temperature down to where you want then consider purchasing or using an air conditioning unit.
