Guys, we are having an intense heat wave in the uk atm and the plants arent doing too well. They are 5 weeks into flower but i cannot get the temps in my tent below about 38c atm because we are having averages daytime temps outside of 30c min. They have started to look limp and the branches are falling over although the rest of the plant looks healthy i think it may be heat stress. They are adequetly watered. Setup is 1.2m x 2.4m mylar lined tent with 2x 600w air cooled lights. Not sure what to do about this as im only a few weeks from harvest but i dont want em to all collapse and die. What is the best course of action here?
take one of the lights out/ turn them down if digital ballast, or replace the bulbs with 250s ?

are you venting the hot air from your tent into the same room the tent is in ?

the heat is more of a problem for me than the plants, my house feels horrible in this weather too humid
but the plants seem to love it, as long as the air is constantly moving
hydroponics works well with high heat as the plants always have a water supply to cool themselves down my temps are 75f lights off 92f lights on

peace

Yea thx for your replys guys .....but......here's a couple of pics to let you no wot I'm up against........I couldn't insulate my door but what I done was fill in any GAPS(this was winter time)with roofing felt .........this had a duel purpose.....1 to keep the cold wind out(I have a 8inch gap between shutter and the frame of the door at the top)this was also to block any light from leaking out (2 recectangular windows) so that no one could see any light coming from around the frame at night time(total blackout)PERFECT......as for venting into the same room .......No ......I have a pipe running into the attic then out of an exhaust port I have for my kitchen fan........

Yeah i have to vent the hot air back into the room with the tent because i live on a built up estate and have lots of neighbours directly facing my house so i cant be running a pipe visible out of the window its too obvious...so to combat this i just leave all windows open during lights on and close em when lights are off. I know it would be better to vent directly to outside through a pipe in the wall or into my loft but i cant as i live in a rented house.

i would always recommend going from room to room or into the loft or whatever rather than outside unless you live somewhere where being
inconspicuous is not important

fan makes a fair bit of noise on the outlet and is visible, to neighbours and folk who walk by
when the lights switch off and there is a rapid humidity drop a strong cut lawn/grass like smell wafts out of the filter, even when you run ozone with it too
so i like to keep it all inside,
i know you said its rented, you could make a small hole in a joining wall with a diamond bit core cutter, you can rent those
they cut through brick very neatly without cracking the bricks and you get a long shaft of brick/concrete you can put back after.
no one would ever know lol

if you cant extract the air out, you could bring new air in directly, that would be the 2nd best thing rather than the re-circulated air in your room getting sucked back into your tent,
you could use an inlet fan to suck colder air in from near a window and blow it straight over the plants, this air will have more co2 and be cooler than the air in your room

Yeah cool mate nice one for the reply. These are ideas ive toyed with a lot but never got round to doing. I thought about making a wooden box around the window and putting the vent into there aswell. If only i could access my loft it would be so much cooler in there. Unfortunatley my loft is kept locked by the cunting landlord! Lol
