Bottom Vents

Have a 4X4 Tent with 700W LED Light.

Problem is it is getting way too hot. I'm vetting into the room the Tent is in. Running 11/13 I have one Vent open at the bottom and it don't seem to hurt anything. Can I open the other Vent?

For sure, open all the vents if you can. Just beware of any light leaking in - you may need to open and close them each day as your lights go on/off. If you can vent the hot air into a different room, itl be a huge help too.

I keep my bottom vents open 24/7. I manage heat/humidity with the door to my lung room.

I sometimes have heat issues, I would definitely open all the vents, you could try having the lights come on at night, when it’s cooler. If you can, and your equipment allows it, you can relocate the LED driver outside the tent. Last resort, small portable a/c unit.
