So I'm roughly 6 weeks into flower. On 12/12. light went off this afternoon as planned. 5hrs later I needed a fan so had to unplug the timer (no real issue as its lights out time) I plugged the timer back in and went about my day. 4hrs later I back in room & spotted light coming from tent so i turned them off straight away & tested the timer to find its on permanently (timers knackered) new timer in place what light/dark settings should I now use, the old settings or new settings based on today's Araghhhh? 12:30 light off for 12hrs 17:30 light on 21:30 I discover & turn light off & reset the timer to come now at new time of 09:30. Is this correct HELP!!
So, if I'm understanding correctly, your lights turned off at the scheduled time, but instead of being off for 12 hours they were only off for 5. Then they came back on for 4 hours. And you then turned it off. You should put them on a new 12/12 cycle starting with 12 hours of darkness from the time you turned the light off (after you discovered it was on). Not the old settings. HTH
your understanding is correct. Only problem now is I'm getting different information from another source. This person says too leave it as it is, that there should not be an issue with a one off light hiccup. This all happened last night and with no information at hand at the time I just left them on the regular setting. Thanks for the advice either way, that was my initial thinking, but indecision lead to going with the flow, wish me well
