7 weeks flower, skip 1 day cycle to change schedule, is this a problem?

Hello! Basically I'm at 7 weeks flowering, and I need to switch my day and night cycle. But I don't want to extend my flowering time any, so I opted for lights off during my day 12/12 and turning them on the next night at a better time to run. This equals about 27 hours of pure darkness. Will this hurt my plants or cause any significant stress? Will it decrease my flowering time a little bit even? The lights run from 7pm to 7 am, I'm looking to push it back to about 10 or so. Normally I would have just done this yesterday with less stressful hours, but the lights(more like my window ac) cannot be on during the day tomorrow.

it will stress them a little.....but should be ok if you stick to a tight schedule once the lights are on again

Sounds good. Will it affect flowering time any?

I have no idea... I've never done it

Plants haven't missed a beat.

could turn it hermie though from switching light cycles

If you are at week 7 you should be fine.

At this point your plants are almost done and its real hard to mess them up light wise the last 2 weeks (if 8-9week strain).

For instance: if you were to set the lights back on a 24 hour schedule it would be almost two weeks before you would see ANY change/revert.

And the extra dark wont hurt a bit.

Extended/extra dark during flower=OK

Extended/extra light during flower=NOT OK

The one exception is the last week OR two of flowering. If you raise the light hours to 13 or 14, or say leave the light on for 24 hours by accident, its too late in the flowering for it to have any real effect before you chop it.

At least that has been my experience. Your mileage (or strain) may vary.
