Tent is way too hot

As someone who has had heat problems, the solutions I used were:

Open a window in both ends of your house/apartment to increase air flow in your place.
Turn up the osculating fan in your tent.
Open all the passive intakes you can, perhaps even the tent door a bit.
Keep a few bottles of water in the freezer, put them in front of the fan, cools the tent for the next few hours. Useful for day time if it's super hot.
Exhaust vent into another room
Have an oscillating fan in your room to blow air around.

Ok, these are all sound ideas. And I did everything but leave the door open and open a window. Can't open windows in winter being -35 and the tent door open would let the room itself heat up. When I started this, the room was 90 degrees in no time. That's just too much for the dogs who also have their kennel in there.
Ice bottles have been mentioned but I've not gotten around to try it. Me and my girlfriend both work shifts, so that's going to get forgotten one day and then it's all cooked.
I really do appreciate all the options you guys throw at be but it would have to be something permanent.

I don't understand how your tent heats up that much. Either your LED is producing an insane amount of heat, or your room temperature is really high.

Another option is taking some ducting and putting it ouside. My tent has a hole by the bottom for ducting, for a passive or active intake. You could run ducting from that and to a colder room/outside. Then it would passively pull in some cold air. Just remember some filter on the end, so you avoid bugs flying in etc..You can use a pantyhose or something like that.

I'm venting to a cooler room, can't vent out. I got these shitty crank out windows and have no idea how I would shove something in there to do that. The room itself is now 77 degrees, stable. The light iswarm to the touch but not hot. But it's the only heat source in there so it's gotta be it. I can't remember what it was called, there's heat and then there's heat. Sorry, my brain isn't working too well right now. Like I can stick my hand in there and find it comfertable. Yef the thermometer shows a temperature I know I wouldn't like. Could be the thermometer sucking up heat, radiating down like someone mentioned earlier.

Thanks everybody who was involved trying to help me with this. I've taken a lot of notes and will go through it one by one. And see what I can do with it or if I've fucked things up too bad.
Like I said, I do have a much smaller tent coming, and if all else fails I'll use it instead. Then all my shit should be big enough.
Gotta find the upside somewhere :)

This resonates with me so here you go..

No heat issues. You can place the air circulator where the intake air comes in and it will push air around with cool air and the hot air exhausting.

A four inch inline fan usually has about 170 cfm.
A 4x4x8 = 128cf.

I should explain more I have cool air being pulled in at about 67. Tent goes up and Lights on 78-83

Off
71 or so.

Add co2 if you can. At 85 and above plants use it best.

Yea, math wise I'm ok. I got 2 fans in there running full bore. The temperature doesn't seem to care about it

Something like this will give you the surface temperatures of leaf canopy or medium temperature or different temps at different locations. (Plants closer to the light/ position...)

I don't have to cut holes. It has em already. My led panel draws air in on top like most, with 3 fans. And blowers it out on all 4 sides. I'm not sure I follow what you have in mind.
You're obviously not a cooking man.

Make an exhaust hood like those over a stove. If you lived around me I'd give you one that's in my basement that came off the overhang of my stove when I installed an overhead microwave.

You could make a light weight one out of a piece of duct work from Home Depot for 6 bucks. Buy a short piece of 8 inch ductwork, use tin snips and cut it open, bend it out but leave it in an arch, cut a 6 inch hole in it (or whatever size duct you're using) and attach it with sheet metal screws. Hang it just above your light and run the duct to a small fan and suck the air out.

The heat will make the air rise up to the construct and it gets vented directly out the roof without being blown around all over the place.

Here's a picture to give you an idea of what you would be building:

Dude, you need to get a 6" fan on a speed controller. It will fix your problem I guarantee it. The 4" fan you have now for exhaust can be used for intake. Spend the $60 more and do it and start growing.
I agree that proper air flow is key to heat issues at least for me as i run two Mars 600 panels (heaters no doubt) in a smaller tent (2.5x4x5). I use the 4" inline fan in my tent with a speed controller and it keeps up but i have a smaller space to pull the heat from then you do. I exhaust out of the room into another room also as you do op. I also run my lights during night time hours in the summer. My temps usually run 76-78f during lights on. I use no booster fans for intake so its passive. I feel for you on the subject because once summer came i found the same problem with the cheaper LED panels. One bonus i suppose is they heat the grow area for a person in the winter thus cutting heating costs but so would HID for half of what i spent on my Mars panels ($300). So i totally get your frustration after you invested your initial money.

I gue

I guess you also failed too look at my pictures above too. The scrubber is in the tent above.

Do people only read there post and pictures only?
Ikid ha
I know it is. But he advised to push air through the filter when you don't wanna do that if you can help it.
