Does this look like heat stress?

Yep. Spot on. Better to start with one and include the second if one isn't enough. Get both CFLs on too and see how that goes.
It should make a difference. The warm air should be vented away from the tent also so the air it pulls in is as cool as it can be

yes i have noticed the pinholes near the seams maybe ill leave it as it is , def just experimenting this time , im hoping she recovers from the nute burn though , the fresh growth is looking ok so all i can do is hope :) and try and get these temps down of course . First thing tomorrow im gonna get all the bottom flaps open , im assuming its the pressure of the air being pulled out sucks the air in at the bottom then, so by running both exhaust fans , should that suck more cool air in from the bottom than if i was to just run the one?

Ok so today ive had a complete change around , ive moved the tent across to the other side of the room .Its a bit more airy that side and gives me full access to all sides of the tent properly. I`ve moved the exhaust fan to the back of the tent and raised it to the top. I also added my air cooler to the tent , the type that you put water into and it blows fans across the water and out. Repositioned the humdifier and tidied all the wires and plugs.Raised the 2 side flaps and opened the intakes at the bottom.
Results :
With both lights on (300w cfls) and 1 exhaust fan the humidity stays between 40&50% and the temps go up to 87 degrees.

With both lights on and both exhaust fans humidity stays at 50% and the tent temp 84-85 degrees.

1 Light on both exhaust fans running humidity stays around 50% tent temp 82 degrees.

1 Light on 1 Exhaust fan as pictured , humidty in the 70`s tent temp between 79 & 80 degrees.

When the humidty was up to 70% the leaves seem to become damp like , so ive been in and lowered the humidifier and lowered the speed of the water cooler. Now the humidty has dropped to around 60% but the temp has gone up to just over 81 degrees.

Any other ideas ? Which setup would be better?

where does your ducting go ?? intake and outtake if its all in the same place you are basically just filling your tent with the warm air youve just extracted....can you extract to a different room ???

i think youve got to remove some of the variables and get it right with the basic stuff first. air cooler will be adding humidity as well as a humidifier...so hatll make it impossible to regulate,,,,, take the humidifier out and see what happens with just the air cooler on

open a window to let fresh air in.......other than that bro, without seeing your setup as a whole im a bit stuck!!!

how warm is the room your tent is in ??

Only got the 1 fan exhausting now to an open window in the same room. Room temp is about 26 degrees c. Ill switch the humidifier off and leave the cooler running see what happens.

Or try this this is my DIY air conditioner but in all honesty mate the fans u have running should b more than sufficient to accommodate that space by the way I made the air/con as a bit of fun but it lowers my temps by 4degrees C by the way the info oil maker is giving u is sound the fans have to b positioned correctly for max performance.

I made a very similar device with a pond fogger in to create humidity. Worked well but too hard to control.

I honestly believe it's an issue with tents. Don't know why but they just seem to be hot.

Thanks for your continous help guys....
Ok so ive tried every possible thing i can think of to get the temps down and still cant get lower than 27.2c (81 farenheit) As soon as the humidity dips into the 40s the temps start creeping up. As soon as i put the second cfl on the temp goes up and stays at 84 degrees, i even tried a 135w ufo over the auto seedling but the temp goes straight up to the same 84 degrees.At the moment i have gone back to 1intake and 1 exhaust fan which is keeping the temps steady at 81-82 farenheit tops. I have been reading about being able to run at higher temps when using co2 . Do you think i could do this with both bulbs running and an exhale c02 bag?

Hi bro

I'm not sure about co2. Never even looked into it in all honesty. Currently dealing with the facet I've put the wrong nutes in my flowering clones and fucked em up so I may not be on here quite as much. What cubic meter is your exhaust fan and filter?? I've just upgraded mine because i cant get enough heat out of my tent too. I'll let you know how I get on
