YOU SHOULDNT HAVE ANY PROBLEMS WITH THIS. IVE DONE THE SAME THING. I SWITCHED MY FIXTURES AND BULBS OUT THE OTHER DAY (GOT SOME DIFFERENT LIGHTS) ANDDID THIS. MY TIMERS HAVE A FIXTURE "ON" SWITCH ON TOP TO ALLOW YOU TO TURN THE LIGHTS ON MANUALLY, BYPASSING THE TIMER. WHEN I GOT MY NEW FIXTURES PUT UP,I SET MY TIMERS,ECT AND SOMEHOW ACCIDENTALLY FLIPPED THE BYPASS SWITCH. I WATCH MY TEPS CLOSELY WITH A REMOTE THERMOMETER, AND USUALLY IN THE DARK PERIOD, IT SAYS AROUND 70 DEGREES, WITH MID-HIGH 80S BEING THE NORM WITH THE LIGHTS ON. I NOTICED HIGHER TEMP AND FIXED THE PROBLEM DIRECTLY, BUT THEY GOT ABOUT 2 1/2 HOURS MORE LIGHT THEN THEY SHOULD HAVE. THEY WILL BE ok THOUGH, JUST GO BACK ON 12/12

FYI...plants dont get "confused" as they DONT HAVE BRAINS. photosynthesis is a chemical reaction, not a conscience physical reaction on the part of a plant. also, plants wont turn into hermaphrodites in stress situations unless the plant they originally came from had hermaphrodite tenancies. tenancies to turn hermaphrodite are genetic defects in the plant, and can be brought on by stress, but leaving your lights on for an extra 2 hours or 4 hours isnt going to generally do it unless it was on the verge anyway

just speaking from my OWN experiences.

How does a hermaphrodite point to genetic defects in the plant? Am curious, as cannabis is considered subdioecious and falls into the angiosperm group... of the angiosperm group, a high percentage is herm by their very nature (75-80%~), < 15%~ are monecious, and the dioecious section sits close to 10%~. A majority of the samples found re: cannabis point to dioecious, but the subdioecious tendencies can/may produce flowers that are not 100% clear as to if they're male/female. Am not trying to argue, am just curious how you came to that conclusion - unless that was summarized with your 'own experiences' at the bottom of the post. Environment can trigger geno/pheno responses, and one of the traits could definitely pull herm, as an aside.

I believe he said "hermaphrodite tendencies" As in, some varities have more of a tendency to show flowers from both sexes i.e, some tropical sativas.

These tendencies can be "bred out" or at least made less common through breeding. Breeders who dont take time to breed out less desirable traits end up with strains with higher tendency to turn hermaphrodite, be more susceptible to disease, etc. You're right, Its not really a "genetic defect", it is perfectly normal. It is more a breeding "defect" i suppose.

I think the whole "hermie" thing is blown way out of proportion. I dont think female seeds are more prone to this condition, nor do I think "stress" causes it. If its going to happen, its going to happen.

I found this thread as I was very worried as the same thing just happened to me, somehow my timer didn't turn off, I had moved the surge protector last night and somehow the timer did not go off on time. I caught it but 6 hours too late. Very Thankfull for this old thread and the information contained and still alive here!!

As far as stress causing hermies, yes, I found that out in about 1980..I was doing my first ever sense buds and one plant (all female) had been almost broken and leaning over so I tied it up and it grew fine but then became a hermie! I considered it lucky for me at that time as I didn't know about cloning and those plants were all I had..so I ended up getting seeds to continue my crop. Sense wasn't that common back then and it was more precious than Gold.

Thanks guys for all the information about lighting issues! :)

I know this thread is old AF, but I got a new tent set it up in the dark cycle with green light. Was extremely careful moving everything over. Until I unplugged an air purifier that has a very bright, blue light LED screen. Went to plug it back jn, but because of the green light di dnt notice the light had switched ON! It was probably on for about 1hr not directly on the plants but I know they could see it as I saw it after closing up the tent. Will this light for a short period cause hermie?

I found this thread to be of some help to me also. I had a pretty similar situation happen...I have UVB lights on a separate timer in my setup and of course I'm over 5 weeks into flowering and left the UVB lights on for 4 extra hours while the main lights were on a timer and went out. So the UVB lights were the only lights that were on. After reading this thread and a multitude of others like it I'm feeling pretty confident I'll be fine. From what I've seen, heard and read plants (especially marijuana) seem to be pretty resilient. As long as theres no prolonged exposure to anything thats detrmental to the plant's health they can handle it. Everything just needs to happen in small increments, whether it's feeding or lighting or whatever. If you screwed up a little bit, as long as it wasnt a catastrophic fuck up, they will survive. Maybe I'm wrong, I am a "newb" and far from saying what I speak is the gospel. Just making an observation.

My dollar store (mechanical timer not electronic) ended up Getting stuck before a lights on and didn't come on. Sometimes it's the timers fault. Next upgrade is pro ably going to be an environmental monitor.

This threads 10 years running and people still be using it.

Don't use a dollar store timer. They are not that expensive and worth paying for a decent one.

I have a wifi one too but it's always failing as well. I'm looking for a good digital timer that dosnt require Bluetooth or WiFi.

I said dollar store but I meant hardware store. The dial style with the pins

I created this account to dig up this thread once again and confess: I too accidentally bumped the timer light to always on.

Approx 37hrs straight daylight in my flower room. 2 plants within a week of harvest, 1 on week 7 of 11, and 2 more on week 4.

Accidentally hit the timer while changing the reservoirs. Caught it on the second night when I entered to retrieve my ph meter at what I thought was an hour after bedtime.

Switched the timer to give them a full 12 hours of dark and will probably cut the day short tomorrow to get them back on the correct timeline.

I promise any fellow oafs out there, who are also stumbling upon this ancient thread in their hour of panic after realizing what theyve just done, that I will save my login credentials, and return once again to update you on how the ladies respond.

Stay safe - and don't be an oaf like me.

Your plants are now totally seeded with herm genetics, if they were fems its even worse like mutations and unstable offspring hermie death type stuff.

No you will be fine the plant probably didnt even notice.

Shout out to my man 2Hearts - my friend on this journey and probably the only other person to read this post.

Few days post mishap and the short version is - everything seems pretty much fine. It may have caused a bit of foxtailing but we'll see.

2 Plants preharvest - still come down tomorrow, there is noticeable effect at all.

2 plants on week 4 - no noticeable difference but it's still early. They are a crazy hardy Triangle Kush that's basically indestructible and would probably be fine on Mars.

Only noticeable "ill effects" are on my week 7 - Skywalker OG. It has been done stretching but since this has put out a few more stringy buds with those stupid round single leafs. I've grown this plant before and that is not normal. To that note, this particular plant is really special. She is unbelievably picky and will punish you for every mistake you make, takes an eternity to finish, and yields "ok" when you run her perfectly... but what she grows is some of the most sticky nasty funk that will plant even the most seasoned cowboys dick in the dirt - so she keeps a spot in the garden. She's probably going to be a bitch about it because she is about everything.

Final thoughts and conclusion:

Unless youre working with an unhealthy plant or some crazy genetics in the first place - one extra long (37hr) day during flower seems harmless enough.

Left my lights on for 21 hours, 5(5 hours extra) in the 3rdweek of veg, should i stick to my normal hours or should i leave them off for 6 hours and change time cycle? And yes im an idiot ‍♂

The most important thing is that you return them to the full 12hrs of darkness ASAP. DO NOT CUT IT SHORT. If you only had 6 hours left of dark - adjust to give them the full 12. If you want to get it back on your time schedule you can simply cut the first day short to match.

The periods are darkness are what causes flowering. A few extra or less hours of light won't change a thing if the plant continues to get 12hrs lights out.

Obviously don't push your luck but you should be just fine.

I misread you were speaking about Veg. As long as the plants don't get 12 hrs of uninterrupted darkness it doesn't matter. They will continue to veg just fine.
