I run sealed rooms, no exhaust- but I do supplement with co2.
The heat is removed by water cooled air handlers, which also dehuey in the same pass.

I'm just not going to be told that a 432 watt t5 ruined plants and can't be run in a small space when I'm doing it just fine.
Been running them for a couple years now. I've worked the bugs out and know what it takes to do it.
I had heat problems among other problems until I exhausted out of the house.

My temps never went above 84 with the same setup and RM3 says in posts elsewhere he gets canopy temps up to 92. This is what you're not understanding here, because you take the fact that I am "new" as not knowing what I am discussing. The temps was not the issue but the plants are being burned. I simply stuffed too much into this enclosed space. The light was three feet plus away from the canopy and there were multiple strains under it. The pictures are in my thread.
If the exhaust was the issue my flower tent would be suffering the same fate as well right?
I put the LED light back in the 2x4 and the plants respond wonderfully with new growth and no more burning. This same UV bulb when I first ran it as a supplement to my COB's by itself burned two of my plants big time. It runs hot, but it's like a radiation, not an ambient temp thing not sure how to explain this part.
Please keep in mind not all grow areas are the same, so just because something is working for you in a 2x4 (though not a tent) does not mean I can duplicate the same results, especially in a different geographical location.
FYI- I will be running the exhaust out this week, because summer is upon us and the heat here will only get worse so I do not want you feeling like the point you're driving is being ignored, the room is a work in progress.

That's fine. That works.
Mono is exhausting the heat to the room the tent is in and then trying to cool the hot air.
Just exhaust the heat outside and problem solved and no need to run the portable a/c.

I saw your post yesterday about going back and forth with people on here brother, and not going to do this all day with you. As I have told you before via PM all of your help has been/is/was appreciated. I am not sure what's up your ass with me today, guess I was the lucky 100th customer or something. But you need to open your mind to one simple fact. You can take two identical size spaces like ours and run the same equipment and get different results and different issues, if for nothing else due to geographical locations.
You win.
I am a newb, I do not know what I am doing, my resons and testing are irrelevant and don't make sense. I will exhaust outside and fill the room with T5's and live happily ever after

No biggie man. I get it. I burned some plants with mine.
Mainly the plants need to be started and grown the whole time under the t5.
Heat is not the only reason I suggest exhausting outside.
Mold is a reason. I had to scrub two rooms and paint with kilz because of exhausting into the house.
The next reason is to air exchange. To replenish the c02 they use.
Ttystick runs sealed with c02 and removes heat and moisture.
For us low budget guys we have a couple options.
The cheapest and simplest is to exhaust outside. That removes heat and moisture without an a/c or dehumidifier. It also replaces c02.
There were other problems I ran into for not exhausting outside. You may or may not run in to them.
I'm just trying to save you the trouble, no matter which light you use.
That t5 has smart ballast. You can simply take out two bulb and it will still run. Or I can with mine.
It is what it is. I'm not trying to knock you. Just stating my opinion.

Pull the UV bulb and change it to see if you get different results.I saw your post yesterday about going back and forth with people on here brother, and not going to do this all day with you.

It takes growing them from seed under that bulb or you will burn them.

I already pulled the fixture out. The COB is back in.
The last day I ran the T5 with one of the banks shut off down to just 4 bulbs and the temp dropped almost 10 degrees, the UV bulb was off............
But now I did not have the entire spectrum running so this defeated the purpose I was looking for.
What I really think the issue here ios "for me" with this particular light is that the fixture is literally the size of my tent basically, so the air from the circulating fans has trouble mixing from under the light with the hotter air above the light due to the ballasts. There were two fans on the floor, and then a clip on hanging from the top blowing across the ballast, inline with the passive intake, blowing toward the carbon filter which is the start of the exhaust.
Now with the LED, you peek into the tent, and even though the gauge is reading high 70's/low 80's as the buckets, the ambient feels much cooler and the air movement inside is great, it feels cooler in the tent than the room........this is why I do not think the exhaust is the issue, because the exhaust is not that hot to begin with........

It is. If you look at my light in my cab I cut four big flaps in the reflector to let heat go through. I didn't need it after exhausting outside.
You will see a big difference even with the other lights when you exhaust outside. You will most likely not need the portable a/c.
