light leaks? does a little bit matter?

hey guys
just finished setting up my dark room for force flowering my outdoor girls.
basically i have a very tiny bit of light seeping through the crack in a door and i cant think of a way to get rid of it? the room is completely dark, cant see my hand infront of my face. but if you look where the door shuts theres a small bit of light.

will they still be okay in there?

cheers, peace

Yep! I've got a darkroom myself and it does that same thing. I've read numerous things about people having the same problem too, and it never seems to affect the plant. Of course, my darkroom is in a dark room when the lights are out, but still, after thoroughly researching it, I am confident in saying you are fine. If you are worried though, find a way to seal that up a little bit. Drape it perhaps?

all depends on how stable they are. and how direct of light it is. light dosent bend, so if its residual/reflected light its usulay ok...but depending again on how stable

I would put a towel or blanket along the crack to block any light trying to enter the room. Better safe than sorry, don't want any hermies.

yea thats what i was thinking of doing, putting a blanket over the door. yea thats what im gonna do. easy , cheers guys

Just think as if it was in mother nature growing somewhere. The moon gives off the relfection of the sun light. So a little is ok. =) Truly it's never 'dark' outside. Not completely anyways.

plz, let me put this debate to rest.... i see this question alot.

lets get all sherlock holmes on the subject, and use some deductive reasoning.......
here it is-

at night time, in the wild... is it pitch black?

no.

as a matter of fact, in tropical lattitudes, there is enough starlight, that one can read by it........ and the landraces dont hermi.

now, you tell me......

i had the same problem but its been good for 4 weeks. but does any 1 know what hapenns if im 4 weeks into flowering and lastnite one of my lights didnt go off when it was supposed to and found out 5 hours after they were supposed to turn off. is it gonna go back to veg stage or am i ok as long as that doesnt happen anymore.

I don't think you can simply put this idea "to rest", since it is a potential problem. The reflected moonlight and distant starlight outside are a very different thing than a beam of light coming through a gap and landing directly on a plant. I know this is not the case in the OPs situatiuon, but it will cause problems. If hermies don't show up, there's a good chance of airy and strange looking bud with a flowering time that just won't end.
Many sativa landraces hermi every time and uncontrollably, and they come from these areas where you could read at night.

yes it does matter if it is later in flower might not matter as much but first half or so seems to matter more

i remember being in Afghanistan long time ago, i guess around herat ... anyways, at night the milky way was like a solid band of light ... high up, it was really incredible ... and that is where all the good stuff grows ...

ive seen it to.

kinda why i mentioned it in the first place...........

but let me rephrase that for the techies out there-

refracted starlight and moonlight, bright enough to read by, does not cause hermi conditions in the wild.
say what you want, but like i said above, ive seen it in action with my own eyes. there isnt a book in print that will convince me otherwise.

intense light, like from a HID discharge lamp, can cause hermi conditions, if it leaks into a darkened room. the reason being, the intensity of the hid light, it has more PAR than refracted starlight, therefore, can cause light poisoning.

perpetual 12/12 does not exist in the wild, except for 2 days a year, and THAT, may have more to do with your fluffy buds and extended flowering than light leaks.....

I been wondering about that for some time now. How does moon light effect the flowering in nature..

Well, moon light is a reflection from the sun like I said, so technically it's sunlight, not nearly as many lumens or as bright...but it is light no matter how you look at it. Just not enough to truly give the plants a sense of light. With canopy from other trees around the outdoor plants, or even in a field of themselves at night they're dark...so is the ground so no relfection. By the time the light gets to your plant from the moon it's so useless. Light degrades over space in intensity, and that's a lot of space from the moon to your crop.

Take a light sensor out at night where no man-made lights can affect it. Measure the reading at midnight at noon. The difference is proof I guess.

But please someone correct me if I'm wrong, I'm stating all this just from knowledge of my own, common sense, and google.



The two days of 12/12 in nature would take place right after the harvest moon...right?

Weather stripping comes if different shapes and sizes while also being cheap and easy to use/apply.

I don't know how you're just rephrasing it for the techies when you were comparing moon and starlight to indoor light leaks, on an apples to apples basis in order to put an issue to rest. I don't have any of the light issues I brought up, but I've seen wacked-out light stressed herms first hand, and they're not exactly prize plants.

I'm not trying to pick your post apart, but perpetual 12/12 exists in the wild at the equator. I didn't really understand that last comment to begin with. In Nairobi, Kenya, the shortest day of the year is 9 minutes shorter than the longest.

try insulation or electrical tape. if you are able to get silicon near you then try that as it has better insulation properties.

Weather stripping is perfect for doors, and if you get extra, you can use it other places where you might want to dampen vibration.
