over heating grow tent

I seem to be having problems keeping my temperature down...its currently growing as high as 36 degrees Celsius
Opened top vents...
got a fan blowing up da grow tent...trying to push heat straight out the top of grow tent.....im currently on my 6th week of flowering. Baba kush..midnight×××2
And my utmost importance python. ..well show some pics

Make sure your fan is drawing OUT of the tent, and make sure it's decently sealed. What kind of fan are you using? It may not be rated high enough.

As Dub said, and also.. you may be able to get in there and trim up some of those big fans at this point to allow more air circulation through your plants. I run a 1k in a 3x3 tent and have no problems with temps using a 400 cfm vortex fan, a tower fan in the corner of my tent, and air conditioning in the room.

Hey buddy thanks....
If I pull of some fan leaves around da colas ...literally under or ontop of the buds..if I rip some out .to let more light penetrate the plants...will this hurt or affect my buds

Hi python, gotta get those temps down, the plants look great for 6 weeks in though. I have a bunch of different tent/cabs and a main flower room. I do different things in them at different cycle times and depending on what I'm doing (different lights, number of plants, size of pots) the rooms can behave differently. I always step back to the basics when I'm having an issue with temps or humidity. Basic rules I use for cooling and humidity control are:
Bring in cooler/drier air - this works the best imo, if you're using passive intake and it doesn't cut it, put an inline or booster fan in or crank it higher (or go bigger)
Exhaust more/faster, same as first one but on your exhaust vent
Increase circulation which has already been mentioned above, sometimes do this with one of the two above.

I'd recommend higher air circulation before defoliation if you can avoid it, I've done some light defoliation with strains that have dense/packed leaves at the end of the cycle but it's usually my last resort and only if I think it may affect/induce mould. Getting the temps down, reducing your humidity and airflow should take care of any potential mould though. Trim off any dead or dying leaves but plucking healthy leaves is best kept to a minimum imo.

Cheers and good luck, not long now...

LG makes a neat AC unit for 300 bucks. 8 or 9K BTU's and it has a 6" vent that moves air even when the AC isn't running. It's ideal for small rooms and moves air like a bitch. Worth every penny since I'm running AC/DE 1.4K open hood.

He is near the end of his cycle a light defoliation will actually be a good thing as those buds start to ripen. I am not sure what you mean by defoliation causing mold, as actually it does quite opposite. Removing some of the larger fans at the end allows more air circulation around the inside and the plant and actually DECREASES the chance of bud mold in strains that produce very thick buds. I certainly don't see how it could cause mold.. but I could be wrong I guess. The defoliation is something people who just read about it often say don't do but the people I know who actually do it seem to like it so do your own research. Just seems to make common sense to me that more airflow = better temps for your canopy.

Are you using a carbon filter and fan combo? My tent is 2X2.5 and I have a 4" fan connected to a carbon cannister. I have the air intake coming into the carbon and out some 4" ducting out of the top of the tent. This setup takes care of most of the heat. I also have a box fan setup outside the tent pushing more air into the intake flap at the tents back rear. Finally I have my oscillating fan inside my tent moving plants. Temps run 78 with lights on and everything running! Once again the carbon filter fan takes care of most of the heat. You need to be pushing air constantly out of the tent. Having vents open without a proper fan ducting air out wont cut it.

Thanks alot for your help...all of you...friggin went in to feed today and temp was 37 degrees....killing meeeeeee...
Look I lifted the lights uo to the top of tent..which now I realize I stuffed up..because u need the hot air to rise to top of tent and out da vents....but if heat remains up there all da time with lights there...so im dropping lights...and taking plants off the milk crates. ..I hope it allows for the heat to escape..with two fans pushing up...im gonna also upload some pics.....very nice. ..halfway through week 7...

I run my tents with the doors open. Saves a ton on electricity by eliminating some intake fans. My tents are in a 150 sq ft room with a 2 ton mini split blowing at them. Temps over 80f/26c will hurt your plants more than keeping a tent open. i still pull 1/4 to 1/2lbs per 600. (have added cfl lighting)
