I already got a fan bringin fresh cooler air in would it be good to get another fan and point it out to remove air from the tent would that cool things down or would it be better to put the other fan to bring more fresh air in?

Typically, your fan should be exhausting the hot air out from the top and cool air is brought in passively at the bottom of the tent.

You don't specify what type of fans you are using, nor what your temps are at. Also, what is the environment like surrounding the tent? Do you have windows nearby or are you growing in a closet?

I would say get a 4-6" in line, venting out, and a small fan moving air. It depends on the size of the tent, but a cheap 4" should be plenty. Also some people open the door if they can while the lights on, you will lose some light containment though.

Your tent will never get cooler than the ambient air unless you use ac. Adding an exhaust fan to your intake will help move the air, but since it has nowhere to go it's going to gradually heat up. Is there any way at all to get some fresh/new air in there? You need to change the air in your closet since that's all the tent gets. It doesn't have to be a huge hole, I've seen cracks under doors that could feed a 6" exhaust.

just cut a hole in the the wall near the ceiling in the the center of the room, use that for the exhaust, and extra fan for intake, one on either side of the opposite wall on the floor and the pressure you build up in the room will move the air through the exhaust hole. I wouldn't waste a fan for pushing air out, use it to push more freshair into the room.

Before I got my tent, I hung plastic from the rafters in the basement. I put one fan pulling into the area and one pushing out. Do you have a fan blowing cold air into the closet through the door? I would have one fan pulling air out of the tent and one blowing air into the closet.

Sounds like your hot lights and your AC are doing battle.
Move your fan to exhaust, instead of intake, and exhaust the hot air outside of the room its taking the cool air from. (your bedroom). Also, if your exhaust venting is long, or has bends, get a good centrifugal fan. The ones with speed control are an excellent way to control your temps.
Good Luck.

You need to vent the hot air out into the larger space, and likewise, bring in air to the passive intakes of the tent from the larger room (along the floor).

If you can afford it, get a 440CFM 6" fan and some ducting and do the above. If you can't afford it, do your best to blow that hot air into the larger space so cooler air will be sucked in at the bottom.

Just get bigger fan and exhaust out and bring passive air in. If you have a return air close by have the exhaust pipe near it. How are you dealing with odour? Its gonna get stinky lol. As others have said you could vent it into attic if structure allows but that will cause huge moisture issues if you are in a cold climate in winter.

A fan blowing into an open closet should be plenty of ventilation. I'm assuming you have central A/C? Is the outer room getting too warm also? If so, you may want to turn your central A/C systems fan to "ON" instead of "AUTO". This will keep the room from warming up too much while the thermostat is only monitoring the temp in another part of the house. The A/C blower running constantly will make a noticeable difference in your electric bill. If you can see the amp draw on the blower motor (not likely), you'll have an idea how much electric.
