    for convenience my light schedule switch on from 9.30 am to 9.30 pm. Grow tent is total czip up light proof outside that time. I have been flowering my bluedream with this time schedule for 6 weeks now. I just got news that I need to be traveling in 3 day time and will be away for a week. So nobody will be around to zip up the tent.
    As u know the sun come out around 6.30am -7 am and go down 6.30pm- 7pm . I can't zip up my tent due to heat issue.
    So my concern is the sun light will start penetrating the room at around 7a. if I stick to 9.30am to 9.30pm schedule. It will have additional of 3 hour of light in the morning. So I intend to temporary Change the schedule to 7am- 7pm to follow the natural sun schedule until when I return, then I will switch back 9.30am to 9.30 pm
    Will it cause problem?

    thank you for your advice, but I will be away for 7 days. And I don't mean extra 2 hour of dark. I mean I change the light on time from 9.30 am- 9.30pm to 7.30am - 7.30pm. Still ok?
     
  4. anyone can advise?
     
  5. As long as the dark period of 12 (or more) hours is uninterrupted...
    You want to make the change where your Light cycle gets short changed by 2 hours.
    So before you leave one light cycle is going to come on at 9:30a - but then they will need to be set to go off at 7:30p (thus having a 10 hour Light cycle) and then the 7:30a-7:30p cycle will begin from there.


    But i'm just a noob, so maybe someone with more knowledge will happen along before you have to leave.
    What i have stated above is just what i did during approx. the same situation.

     
  6. I meant it as 2 days of transition, plus when i said extra hours, im assuming your gona cut off the lights early the night before at 7 to dtart the 12 hour night cycle
