switching sunrise/sunset for 12/12

Im currently on 18/6 where 5:30pm is the sunrise and 11:30am is the sunset. It would be great for temperature control, and although its not a big issue stealth would be increased if I were to run 12/12 on 9pm to 9am. Would moving dawn effect my crop since it seems to me that common sense would have people moving sunset. thx for any help

i moved mine but only by about 15 min they didnt seem to mind although i heard you can stress them that way not sure how a few hours change would due try it and see if they get stressed just use superthrive a few times and they prob be ok

You have two 'easy' options. 24 hour light period, or 24 hour dark period. Then back to 12/12. It doesn't really matter which you choose(as far as the plant is concerned).

alright so at 5pm one day, the lights will go on, I will cut it off at 9pm and then turn it back on and switch to 12/12 the next day at 9pm?

Right, that'd achieve 24 hour darkness and may negligibly shorten flowering time. More light may negligibly increase flowering time. The choice is yours.

alright thanks so much, Im going to go with 24 hour dark mostly for heat reasons...+++rep

i run 7pm - 7am for the temps, its fine
