    Default High temps during lights out, problem?

    So I'm a few days into flower, lights are out 10am-10pm been having really hot weather in the day when lights out, temps going up to 32! Is that going to be a problem that needs sorting or can I get away with high temps when lights are out? Cheers lads

    If your temps are 32c when the lights are off, what temps do you have when lights are on?

    i had same couple weeks ago,32-35 lights out temps,was crapping myself lol,but all seemed ok plant wise,they did a strange thing where they didnt droop as normal and they kept praying to a non existant light,wierd as fk.

    all my fans were on including air boost fan and the constant change of air got them through it i think.

    they went to harvest ok,they did yellow up very very quickly but the bud was solid,not airy at all.

    32c should be OK, but as Rockhopper says, what are the temps with the lights on!

    Myself, I'm going nuclear on summer temps with a serious upgrade on my ventilation

    Temps don't go higher than 25 at with lights on, but that's cos it's cooler at night. This week weathers going to be cooler so I should be ok. But it's start of July so going to have some hot days coming up, will I be ok with these temps of 32 with lights off? Or will it need sorting the further I get into flower cheers lads

    Proper conundrum this one. I run 12/12, lights on 8pm to 8am (night) even on the most recent of hot days with the extraction running at full tilt my lights off temps never exceeded my lights on temps. Are you running your extraction 24 hours? Or does it go off during lights off?

    I hit 32 with outdoor temps of 40 the other day, day and night , plants seemed to love it tbh , of course they drank 3 litres of water per day . and fans blasting all around them of course, and light misting just after lights out
