So I have some heat and humidity issues that I been having a hard time keeping under control. In my 4x8 grow tent I have two 1000 watt Mars Hydro led grow lights , two Ac Infinity 6 inch fans and filters , a dehumidifier and that set to 65 . The problem that I’m having is that when the fans are set on auto the suck in the text so hard that it keep breaking the poles. Plus I can’t keep the temperature under control with everything in the tent .

Maybe....Connect the two fans to a single controller.
1 fan sucking intake air
1 fan blowing exhaust air
Both will operate at the same speed to bring in cool and push out the hot. No tent suck.

I wanted to do that but they sent me two different controllers haha

I only have a single 6" T6.
Exhausting hot air.....passive intake thru bottom vents.
Try running one fan exhaust, one fan intake at same speed.
The controller in your pic has a second port for another fan to plug in. Tried that?

Take the dehu out of the tent and put it in the room, it wont keep up with the rate of air exchange in the tent and its adding heat.
Open all your intake flaps on the lower portion of the tent.
Do what tint suggested.
Them lights are low power, shouldn't be hard to keep temps a few degrees above ambient.
What temp are you aiming for?

What's temp/humidity of room outside the tent? My tents tend to stay around 10F warmer than the room they're in.
+1 on taking the dehu out, those make a lot of heat.
If its sucking that hard you need more intake like has been said. More vents or a fan blowing in at 50% of the exhaust rate. But I have a 1000cfm pulling out of my 10x10 with just passive intake vents with ac air filters taped over them.

Yes I tried that and the controller is different so when you plug both in there on fan stays on no matter what
The tent is going to 83 which I feel like it’s to hot for the text plus my humidity is going from 65/72 which is unstable

Whats the temp and rh of air your pulling in( your ambient air)?
Are you venting the heat outside or recirculating in the same room?
83f is nothing to worry about with LED, 72% rh though.. different story.
the Temp in the room stays at 70 % I have the ac on I just wanted to have more control in the tent

Something isn't working as it should then.
The lights are only 150w each if they are mars ts 1000s , if your ambient air is 70f you shouldn't be getting a 13 degree rise using 2x 6" fans, or even just one.
But like I said, you need to take the dehu out of the tent, that's a lot of heat and your exchanging air, a dehu cant lower the rh as quick as the air is been exchanged, so its a pointless bunch of heat. Better to try lowering the rh of the room.
Where is the sensor for the temps?
If your constantly recycling the air the RH is going to go sky high unless you have a pretty big dehu.

Just a thought but 83 seems fine for running LED's
Ok just was freakin out
Going to do that

I turn the heater on if my tents get below 75 for too long.
They like it warm and humid, you just gotta control the humidity because of fungus liking the same conditions so much.
I try to keep my setups close to 80F/50% I have opposite problem of typically being 25-30% relative humidity though

Try moving the temp probe somewhere else, like one near the root zone and one at the canopy level, but make sure it is not inappropriately heated up by the heat of the lights.
Have the output fan set to a max setting of maybe 6 and the input set to max 10 and min 6-7. That will keep a slight buldge in the tent

Yeah my humidity has been the problem before to keep control so that’s why I
ok
