Lights out question

So I always read "never let ANY light in during 12/12 lights off period" what about very slight glow coming from under a door? Aren't plants naturally expecting there to be some moonlight? I have a closet that i can't seal completely.

the moons glow & the artificial light from ur closet r different things. you CAN stop the light leakage, I grow in a closet with the same problem. I have 2 black cheap walmart sheets attatched to nails on the top of the closet (above where u open the doors) on the inside, & nailed to the side walls of the closet. u put ur nails up & just push the sheet through them. I do this every morn when lights go out. easy to get in, because I just unhook the sheets from the middle of the closet, & let them fall like drapes to the sides where they r nailed in. it can be done! if not be prepared for hermies. I hope I explained that well enough. My closet is a 3 sliding door type...so I have to worry about leaks in several places.

that small light isn't going to make a hermie. moon light is way brighter than that. you are fine unless there is a mirror on your floor and hitting your plant in the face. even then it would have to be a pretty bright light to disrupt anything.

the less light leaks you have the better. I also had a small light leak that came from under the door because it didn't seal completely and gave me hermie problems . be careful with light leaks for you won't be so happy when you discover your lady made seeds ! just my 2c worth.

It is a very little amount of light I don't even know if the plants will detect it. It will take quite some effort to eliminate all the light so I am hoping this tiny amount won't F-UP my first grow.

well "hope" away then, but if they do hermie, just remember the wise ones of us told u so but I am sincerely hoping it doesn't happen to u.

I am not ignoring the advice.... I am just trying to understand how and why things work so I can determine if spending a bill and half a day is worth the effort.

certainly dont want to be argumentative, but yes u r ignoring the advice...you said It will take quite some effort to eliminate all the light so I am hoping this tiny amount won't F-UP my first grow.

meaning ur not going to do anything to prevent the light leak, which u have been told "can" hermie a plant. Sure I like to know the hows & whys to, but there is no big answer for this one, other then u r not dealing with exposing these plants to natural light. u r unnaturally growing a plant meant to be grown outdoors in gods beautiful earth & under his sun & moon. Once u take it to growing inside, well u have to add nutrients, that soils dont have like the great earth, u have to manipulate artificial light & try to duplicate the spectrum of the suns rays by the season, understand? it is simply a fact, any artificial light leaks for indoor grows can cause hermies, not will but can; this also could be the difference in how sensitive ur strain is.

Now I dont understand ur reference to spending a bill and a half a day? for what? and I do not equate money spent in the same sentence as "effort" which requires nothing on ur part in monetary means. I think it is just that, u couldn't be bothered putting forth a little extra effort to rig something up that couldn't cost more then a few dollars to ensure u have no light leaks.

I have a theory I can't back up. The more wattage you use during the day, the more light-leaks the plants tolerates - as it's all relative. A 250W system will tolerate much less light-leaks than a 1000W. Might not be true

a theory worth giving a moments thought, hmmm, okay, maybe, but I doubt & would not make an experiment project out of it...just me as I dont take all the time & effort in veg, to now experiment in flower...on no, I WANT that end result!

not trying to be right at all, trying to give u enough food for thought, that "might" change ur mind to what I think is best, true...but in ur best interest. But UR plant, UR grow, has to be & will be ur choice. I would just hate to see u be disappointed when it could have been avoided. Hey, I am a Peace & Love ol' wise one!

I like it.... Now we are utilizing this thread the way it was intended. Thank for the input KroK It would be an interesting study/experiment trying to prove it.

Sounds good.... I am just here gathering info and not looking for an argument. If you knew the kind of closet I have and what I am dealing with then you would understand, but there is no need for me to prove anything........ you can just take my word for it. Right?

The solution is simple, put a rug or anything easily moved over the crack like those draft snakes for the bottom of the door. It only takes 2 ft. candles of light to disrupt flower initiation. This is much stronger than moonlight on a full moon which is 0.02 ft.candles. Moonlight has nothing to do with light interruption. With constant light interruption you will probably have trouble in the flower cycle and will not set good buds or none at all.

The light pollution is not an issue in vegetative stage because the plant will veg in light cycles from 18-24 hours. If you want to gamble 12 weeks of work don;t correct the problem and take your chances, but don't say you weren't warned. There are numerous easy solutions to this problem if you are committed to growing.

This statement is blatantly false. The intensity of the light during the day hours has nothing to do with the amount of light needed to stop flower initiation.

He never said this was a fact but a personal theory. I seem to recall reading how plants have different measures for dealing with periods of intense light (like a high noon sun at the equator on a clear day), and it would seem to me that this would play a role in the development of a plant that had noon sun for 18 hours VS. a light that was say 60% of the noon sun. It would be logical to assume that the plant that was exposed to lower intensity light would be more sensitive to lower light levels as it would have less natural sunblock. That being said, like the original poster I got nothing to back it up and I am not saying that there is any basis in fact for this theory.

Light leak is gonna hurt you...better to just cover it up...maybe a draft guard at the bottom of the door would work better for you and be a little easier to deal with than a sheet.

My buddy thought light leaks were "no big deal" too....moonlight, blah neon street signs blah blah (lazy). He had the smallest little pinhole of (moon) light coming through his AC unit (swamp cooler type) and he didn't cover any of the little red power cord lights with black tape. I kept telling him...."better safe than sorrow!" (I'm a lightproofing NAZI).........Anyways.......Long story short, guess who ended up with 2 pounds of the seediest Bubba Kush you've ever seen? Wah wah wah.

WHERE in anything I wrote, did u take as I was getting mad? U should learn how to read or interpret better, IDIOT...wow! Some people's kids, lol. There was never conflict, or anger, or anything. I simply gave the best advice, he decided he didn't want to take it, we agreed to disagree & then u come chiming in without a clue. So please get one next time u refer to one of my posts, thank you.
