    Shift Light Cycle

    Hello, just looking for a few opinions on shifting my light cycle. I have three flowering autos in a tent an my attic. The weather is getting hot so daytime temps in the tent are getting up to 33 or 34 for maybe 5 hrs in the middle of the day. Up to now the weather has not been great so temps were pretty ideal of mid twenties by day in the tent.

    I'm contemplating a sudden shift in light cycle so the lights are off during the middle of the day. I guess I have the following concerns

    1 Should I bother, is it ok if temp is high for a few hrs only each day
    2 would a sudden 12hr shift in the light schedule mess up the plants. I intend having one very long day to lead into the schedule shift
    3 my tent would probably end up hotter during lights out than lights on even if I make the change. Would this be a bad idea for this reason

    Any advice appreciated.

    Autos can deal with 24/0 lights, and may prefer it. RH when the lights are off would be my concern, but I grow outside in Oklahoma heat. I would extend the light off time, not the on time.
    Why 12/12s? Autos will flower under 24/0 starting at 3-5 weeks old.


      They won't mind but like Rwise says why 12/12 they don't care as long as they get 18hrs of light or more is better for bud growth. How long they been in flower?

        Thanks guys. 1 plant is about week 10, 2 others week 7. Just to be clear, I'm not intending to change the no of hours the lights are on, I just want to change the time of day the lights switch on and off. At the moment the lights go off at midnight for 6 hrs. I would like to change it so the light goes off at 12 midday for 6 hrs so they are off in the hottest part of the day. Just not sure if it will shock them by making such a drastic change in one go.

          What she said!

        Ok thanksguys. And would you be concerned if lights off temps are higher than lights on? Even so I'm guessing this is the better of two evils if it avoids getting up to the mid thirties in there
