Unless its a real emergency then do it but you are risking having those plants revert back to vegetive or hermaphrodite. Cannabis is a long night plant so its needs that 10-12 hours of "total" darkness, I've read somewhere that just 30 seconds of light during dark phase can stress the plants so like I said if its not a real emergency then you can wait until the light come on or take that risk.

This is fucking nonsense.

Keep it under 30 minutes, don't do it every day and you'll be fine.

I have two females flowering beautifully in my window.
My bedroom light has always been on and off through out their sleep cycles. Plus I usually have my tv on all night, and their not directly in front of it but their pretty close to it. To add to that theirs street lights on across the street. ZERO signs of being hermaphrodites. I've even messed with them, trimmed them, took pix of them through out the night of their entire life.
They'll be fine. Just try not to use a light powerful enough to give them energy, go in with a flash light or something. Maybe that's why i'm getting away with so much light leak is I'm not growing with artificial light.

haha your hilarious your probably sitting in front of your computer waiting to argue with someone hhahah yea its nonsense to advise someone to introduce light into a flowering room. Maybe one time won't hurt but give this a read and then think about it but then again its probably nonsense

Light Response Why You Need to Know: Length-of-night determines flower-set for cannabis. Unless you have a grasp of this fundamental aspect of marijuana physiology, you will fail, to some degree, in your endeavor to grow weed. While it is not necessary to fully understand all of this, it does make for interesting reading. You were probably taught that when you reduce your plant's light period (photoperiod) to 12 hours or less, your marijuana will begin to flower. This is functionally, but not factually, correct.

Cannabis is what is commonly called a short-day plant. However, this is a misnomer, because what cannabis (and all other plants that flower by day-length) responds to is not duration of light, but rather, duration of uninterrupted darkness. Cannabis is a long-night plant, not a short-day plant . When the length of contiguous (uninterrupted) darkness equals or exceeds 12 hours (this varies somewhat by strain), then the plant begins to flower.

This is not just splitting hairs. The plant has two phases, the photophile phase, which is induced by the presence of light, and the photophobe (or skotophile) phase, which is induced by darkness.

This is an example of something you already knew, but perhaps didn't know you knew. Allow me to prove it to you: You would not have a problem shutting lights down during the photophile phase if you needed to relocate a ballast or change a lamp, for example; but would you flip the lights on during the skotophile (dark) phase to show your plants off to your friends? No, you would not. You know not to do this, so you know that contiguous periods of uninterrupted darkness are critical to your plants' flowering mechanisms, whereas contiguous periods of uninterrupted light are not.

Your plant flowers under conditions of uninterrupted darkness--12 hours is sufficient. A flash of light, even for just 30 seconds, will disrupt the flowering process. However, if you do accidentally flash your plants, a final flash using light with a 730nm wavelength will make things okay again.

Interested to see how your quality is with all those lights being introduced during dark phase. Only if growing top shelf quality was as easy as you make it seem. Its also funny why the green light was even invented and any grow/commercial grow I've been wouldn't even allow a phone to be in the flower room during dark phase let alone take a picture. But hey if its working and the quality satisfies you I can't argue with that.

I can see what you're saying but I
think your taking it to the extreme. I personally enjoy the scientific detail you go into. I'm not like other growers who just follow some guide and don't really understand the science behind horticulture. A lot of idiots on here that give shitty advice as far as "the plant isn't dead so it's doing great" I'm a perfectionist.
But in this situation he's completely fine to disturb their sleep a little.
I think these plants are more intelligent and resilient then we give credit for.

They are in stellar condition. Growing very potent. However I won't be getting more then like 8 grams between both plants. This was just an experiment grow. Didn't think I'd be getting anything when I started.

Yea this plant is a special living organism and very resilient ,I know a little light won't hurt probably but if people are suggesting that its okay without any explanation then this person might think its okay to just keep doing it and whoever else stumbles upon this post. My original response explains the "possible" risk in introducing light during 12/12 and that he can wait until lights on just didn't want to respond with a simple "yea its okay"

Yea. I definitely know what you mean. Some random person you dont know just says "yea" . These are idiots that actually don't know. Their just doing things based off what some one else says. I think it's valuable you at least gave a reason with it.


Ok.

I'm always on the prowl for desktop growers giving bullshit advice.

There's plenty of growers on here that will tell you its no big deal.

Plants look nice for being grown by a window, as another experiment try giving the plant actual total darkness and see if there is a difference in potency because we know light can degrade thc but like you said your not using artificial light so that might not even matter just give it a try why not it definitely won't hurt.

What strain is that by the way it might be genetic as to why its not so light sensitive

These plenty of growers on "here" you speak of are most likely desktop growers ,I can go on about my experience but my threads speaks for itself but yea my advice is bullshit and your advice of keeping it under 30 minutes sounds like desktop grower advice.

Can you even explain why 30 minutes ? why not under 20 mins or 10?

Because it's WORKED for me. Real world experience.

Not "I've read somewhere.."

Wow I really wish I knew what strain. Two completely different strains growing side by side in the same pot. One I can tell to be a sativa, the other an indica. Neither plant has more than 5 blades to a leaf.
And don't get me wrong, for the most part they do get plenty of darkness, but just about every night the light is on just long enough for me to pack a bowl or find the remote, then the light goes back off. I am conscious of their sleep cycle, but I pretty much live in my room so light leak can't really be completely avoided. I don't really believe light leak causes hermies, I thinkI it's a gengenetic thing. OR light leak from powerful grow lights. Because if it's strong enough to mimic the sun the plant is gonna freak out and think our planet is going to shit.
