You need some type of extraction fan probably unless you can have a door or window wide open, what sort of bulb are you using?

You need an exhaust fan at the top, there are 8",6", and 4" ports near the top of most grow tents. Rip the Velcro patch off the bottom to provide a passive intake. This should be more than enough air flow for an LED grow, you just need something to keep the air from becoming stagnant, and to combat against hot/dead-spots in the air.

No, you need to exhaust air out of the tent from the top. a 4" inline duct fan will be suffice for a LED light.

You want to keep it 70-80. 88 is pushing it. 92 = bad news
You need an exhaust fan in a grow tent. Just blowing the air around the tent won't cut it.

What's the ambient temperature? I was under the impression that LEDs dont give off much heat so if you're hitting 90 degrees, I'd imagine theres high ambient temps. If that's the case you may want to look into an air conditioner.
Finally a response that makes sense.

What do you mean the ambient temperature? (sorry im new again remember ) but I opened up all the vents to the tent, the only problem is that its in my closet. So basically I need an air conditioner or an exhaust fan? also the tent is small its a 2x2x5
i have never had a high temp problem...but i dont see the reason to worry to much, i mean stagnant air is one thing that definitely needs to be addressed, but 90 isnt anything to worry about, as long as you can get some fresh air in there...think about outdoor growers, and mid summer temps...well above 90 most days, and theres turn out just fine.

As a couple people have already said you need better ventilation. A 4" fan is probably good for your tent because you are only using LED, suck the air from the top of your tent, that is where all the hot air is.. Dont watse electricity and $ on an AC unit unless it is still hot AFTER trying to vent it. With good ventilation your tent should be around the same temperature as your houses ambiant temperature.

A 4" exhaust fan? I am going to put up a picture so you have a better idea of what I am working with

In your picture ther looks to be a port in the back of your tent wall. If there is one near the top, setup a fan to exhaust the air out. the open vents will act as a passive intake and allow air to come in.
I have a very similar tent for my seedlings with 8 T5's and it was hot until I had the venting sorted out.

Hey MrDblock,
By ambient temperature I meant the temperature in the house normally. For example, my house stays at 70 degrees everywhere. Except in the cabinet that I grow in, it gets 75-79.
The reason I ask is because if your ambient temperature is in the high 80s, these suggestions of venting it out isn't really going to help. You'll be venting hot air back into hot air, and then taking in hot air. If that makes sense
