I have read a couple of different places that, during flowering, plants need complete darkness to do their thing properly. That even a tiny LED light can disrupt the plant.
Is any of that true?
If so, I am in big trouble. I don’t see how I can have good air flow, proper temperature and humidity while also blacking out my grow space.
As always, I eagerly await your wisdom.
Some stats listed below.
Thanks in advance!

Yes, even ambient light from your equipment can cause a hermied plant. It can also cause flowering plants to slow their growth. If you have any equipment that has even small lights on it you need to cover with black tape or something equivalent. You should also sit in your growspace with lights off and be sure that you have no light leaks.
It’s possible that even with some light that you won’t necessarily have a issue. But why risk it, having a hermied plant in your growspace, especially if you have other flowering plants isn’t a pleasant experience
I don’t know. For my indoor grow I put a blanket over the tent. Outdoors we have street lights, solar lights and motion activated flood lights. I have not had a hermie yet.
I’ve seen people make that point, same thing about full moon. Nearly everything I’ve read here and on cannabis growing websites say that light leaks and inconsistent light schedule can cause a hermie. But they mainly talk about genetics and environmental stress. I think I’d prefer not to take a chance and just try to keep all stress factors to a minimum.
With autos it really does matter but if u have photoperiod plants in flower they need a full 12 hour of darkness and if they get any light in the tent in that dark period it can affect the plants flower cycle
I don’t know about indoor, but I do know outdoors. As @JaneQP said…street lights, motion lights never had problem either. I did read somewhere a long time ago that the light had to be bright enough to read print on paper to disrupt the flowering. True? I dunno, but as @Bulldognuts said why chance it if you can control it. I wanted to shoot out a store light one time cause I thought it was going to be a problem…it wasn’t and I didn’t
I dunno - I actually had a humidifier in my grow space that had a green light when on and running (fine), but it turned red when it ran out of water. So in the middle of the night when everything was dark, that stupid little red light would kick on. I think that must have happened every two or three nights for a month before I realized it was on (with lights on you can’t really see either the green or red light on it).
None of my plants in that tent Hermed, and the buds were nice and dense. Maybe if I didn’t have that light kick on every now and again they’d have been better but I have no clue. Moral of the story is it didn’t herm and everything seemed fine. I’m with @JaneQP that outdoors ambient light is very real. But I’m also with @Bulldognuts if you have LEDs or equipment with status lights, you may as well cover as much as you can.
One of the first things I learned about on forum was that ambient light could cause a hermie. Equipment lights, light leaks, or repeatedly exposing plants to light during dark periods. I’ve not really researched this personally, aside from occasionally reading some information on cannabis diagnosis websites. Most of what I’ve seen emphasizes stress related issues such as temperature, nutrient issues, like deficiencies or even burn. Basically anything that could cause stress. I have read on sites that light leaks can cause a plant to hermie. The big one is genetics, for example, why does one plant hermie and one sitting right next to it, exposed to identical conditions doesn’t. It would have to be genetics, I would think. So everyone will have to decide for themselves if allowing light leaks or ambient light will be a issue. I tend to err on the side of caution.
Two of my outside girls were on the end of the deck closest to the kitchen, where we run a set of under-cabinet LEDs at night - all night, every night.
The plants were on the porch about 35’ away and through a Low-E picture window size window.
I used PPFD Meter on an S21+ and couldn’t even get the needle to move near the girls. The full moons, in fact, actually did register, but just barely.
Even though the lights appear bright to our eyes the amount is nothing compared to what a plant actually requires.
That being said - i don’t open the tent during lights off for any reason and I would cover any source of long-burning light on any peripherals I was using except green colors. That won’t effect a plant.
Plants appear green to us because they reflect, and therefore, don’t use light in that part of the spectrum. Same reason a blue jay is blue and a apple is red.
Mine is completely anecdotal, but with my auto, and especially my photo, my lighting schedule has been all over the map… I open the tent during “dark” time…do basically everything wrong, and have not had a herm
However I do lead a semi charmed kind of life, and I seem to get away with all kinds of shit normal people don’t get away with
I have never had that happen but if the darkness should be complete I will do my best to make that happen.
I heave attached pics of my grow area and I am open to suggestions on what to use and how to hang it. Obviously, it will have to be opened everyday for airflow, temp and humidity control. The panel I use is reflective and easily I’d to open. The open space above helps with air, temp and humidity.
It is difficult to see but the nook is where the light is. It is in a corner with a window perpendicular and a closet on the other side.
Always open to suggestions.
Thanks, Ms.
