Does this look like heat stress?

Shouldn't b a prob bud as long as ur still able to get plenty fresh air into ur room.that fan in ur pic is the same as mine I've got one intake and one exaust and a standard desktop blowing inside to keep the girls on the moving works for me.
Can i ask what grow space and lighting u use and what temps u maintain with the same fans?
I do have an air cooler im thinking of putting in there tomorrow as well. Would that b a good idea?

All depends bud my room is 6ft'6ft'3ft with 5plants in it.It is a bit crowded but I manage to keep my temps between 28c on sometimes slightly higher and 20off my humidity is usually between 40/60 so it's just about right do u have a fan blowing inside ur room that defo makes a big difference?

I have a clip on fan blowing across the cfl and a tower fan on swing blowing across the tent.y exhaust fan blows out into the room and the intake is taken from the landing which is airy as most of the time the windows are open.

I`ve just checked the room temp in which the tent is in and its 82 degrees as well , i might try and cool the room tomorrow,im assuming this is the problem thinking about it.

Greenhouse;save.... I bow out knowing this guy is in good hands. As I've stated, you have good knowledge and i respect it and you.

My flower room is at 30c with 30RH to encourage resin to coat the leaves and protect it from drying out. It was written by Jorge cervantes and i read it and I'm doing it. The same goes for.temps. I vegged those. Clones in that same temp for three weeks at 29-32c because i couldn't get the heat down. the first two clones died of overwatered the second two flourished when I put RH up to 70.

All I'm saying is its possible to negate the heat by raising RH.

Check my thread "first grow.ever" and have a look at them. Three weeks old and over 22" tall and bushy as fuck.

It's only my 2c

Good luck bro

28.4 degrees celcius
Hmm, I know that the Rule book says its too high but I don't know how youre gon get it down.

Leave the door open?? 300w cfl??

I got two 300W CFL in my 1m2 room and my fan sucks that heat right out??

I'm down to 24-25c in hot weather. Which is perfect :/

Is there a heater in your bubbler?

Upload some pics of you grow area. Walls, insulation, equipment etc. If you grow in a tent it can be really difficult to regulate temps

My air pump is outside of the tent as u can see , both fans exhausting , i will be changing them back to in/out tomorrow.
The other cfl that i would have liked to have covering that poor auto is switched off until i can get the temps down and if i cant wont be going back on .
Anything you notice that could help?

dude where does the ducting go ?? in should be LOW out should be high as poss, thats why your passive intake vents are at the bottom of your tent..you shouldnt need an intake fan in all honesty. out take as high as possible on the opposite side of tent to the intake23TEN010-484878W-N-setup.jpg
ignore the filter at the bottom.....it should be at the top..... ill find a better pic.......you have no cool air coming in is my guess

The ducting goes out through the top panel flaps of the tent through the flaps in the diagram, so i should get those fans up to the top of the tent? My intake up until this afternoon was in the bottom left by the humidifier, the flap is still open slightly to allow air in.

yes bro......just try one fan on at the very top of the tent sucking air out and open all the flaps on your tent....... see how much of a difference it makes.....if not enough put the other fan on extracting too also at the top of the tent. it should work.......you will need a filter though at some point because it will smell more as it gets bigger

i was worried by leaving the flaps open at the bottom about light leaking in? Or should i close them every evening?I`ll open all the flaps in the morning and see if it makes a difference , hope so :)
thanks for all your advice so far , appreciated :)

yeah youll have to close them if you cant keep the tent in a dark place......BUT you can veg for 24hrs a day which means itll only be a problem in flower

i veg 18hrs a day just to be kind to my ladies lol

thats the light cycle im running at the minute 18/6 , can i switch that to 24 without stressing the plant?or maybe switch to run the 18 hour cycle of a night time and dark during the day when its warm.

switching isnt an issue as far as i know, your plants are already stressed so it might be worth experimenting with your grow environment and setup for your next run....

lights off in the day is ok too BUT you cant have any light leak or youll be inundated with hermies,,,,,,

i have lights off when it pitch dark outside on in the day. just helps with light leak issues..... you will defo have pinholes in your tent too

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?
