My plants are at third week of 12/12 flowering, and doing well. But because of rising heat (and an incomplete ventilation system), I'd like to switch to night lighting.

My primary question is this: I know the best way would be gradually change the on/off times (like an hour or two difference each day).

But I was wondering if I could simply run them through their twelve-hour cycle today, keep the lights on (but on low) through the night, and then turn them off tomorrow morning.

But it is safe fof the plants? I don't mind if this might do some minor damage--but obviously I don't want to lose 15 plants because I didn't ask the experts first.

Thanks for the input!
