Extreme temps...what to expect?

My room has been running really hot over the last week thanks to a heatwave. Av temps 32-45c . The girls have been heat stressed a lot in the past but never to this degree. Have canoeing at the moment and growth has slowed right down but wondering what else to expect if the temps keep up? Short of a portable aircon any ideas to help them get through?

Get some air moving around in there and lower your ppms of your nutes so they dont drink to much nutes to fast. Can you turn off half your lights to keep the photo period going and reduce half the heat generated from the lights till heat wave passes, alternating the lights on each day over plants so one side doesnt get the light all the time. Raise lights up a bit might help if thats all you can do.

Unfortunately, if you're not able to control room environmentals it will cause some funky growth . When I ran a few 'freebie' seeds along with my normal indoor grow last winter it turns out they were VERY sativa dominant and didn't finish until May. Room temps were in the mid 80's and resulted in quite a bit of fox-tailing and larfy bud. Still potent weed and made some great meds but just didn't have the aesthetics. I suspect the plants will survive but your results will suffer.

Thanks guys, am running 2 canopy fans already and will raise the lights a few rungs. Have been told to put frozen water bottles in the res as well which i will try. Just hoping it doesn't last too much longer.
