31.5 degrees celsius too hot??

Had no probs through winter.running at a steady 20-28 degree celsius.now its warmed up its hitting 32 at its hottest.they look ok at the moment but worried that over time it might be too hot for them??

i would say so. you would want to be at 23-29 cel

got to get temps back down...do what ever it takes to get every part of your set up and growing skills to get it all perfect [video=youtube;dtQYUgTD6qM]http://www.youtube.com/watch?v=dtQYUgTD6qM[/video]

it really depends on your air / co2 situation. if you have enough air flow or are using a co2 injection system higher temps are much easier to deal with for the plants.

chances are you are only hitting those peak temperatures for a few hours, which the plants can deal with easily.

also how you are growing them. if you have a hydro reservoir in there sustained 30+ degrees is bad.

Basically as long as you aren't sustaining that temperature all day with little or no ventalation or co2 injection you should be okay.

Thanx people using coco + at the moment and 600 hps for light.full extraction filtration kit and 5 extra little fans.still hitting same temp but think ive just got to prey now lol + still on veg so hopefully wont be to bad when drop to 12/12 and yes only hitting top temp for maybe a few hours.so hopefully all will be good .thanx again
