Ok so my question is, how come indoor plants are so sensitive to light leaks? Ive read that they can cause hermie's, and stun them, stuff like that. But outdoor plants are unaffected? They can get hit with light from cars porch lights street lights stuff like that with no problems. Ive done a few outdoor grows and now have moved to indoor and it just boggels my mind... Is it because of how much light the sun gives the plants that the little it my receive at night doesn't bother it? Or does the plant some how know its indoors? I don't understand. I would assume its the amount of lumen's a plant receives form the sun vs. artificial light. Any info would be greatly appreciated.
Porch lights and such definitely can affect MJ growing outdoors. Indoor plants can in fact tolerate a tiny bit of light during flower with no consequences. The problem is that every grower has their own idea of how much light is a tiny amount. People get confused, thinking things like "well the moon is bright." No it isn't, it only looks bright to us because we perceive light, we don't experience it directly like plants do, and it seems brighter than it really is because of the contrast against the pitch-black of space. Indoors it's the opposite with our eyes -- compared to the brightly-lit room we were just in, that "little bit" of light leaking into the grow space actually is too much. If we used light meters we would be able to tell these differences, but we use our eyes sending signals to our brains, which interprets light subjectively. Plus, the amount of light that a given MJ plant can tolerate in flower varies from strain to strain, even plant to plant, and possibly from one part of the flower period to another, so it's impossible to define a certain limit that is OK for all MJ plants in all circumstances. And even if you could, there always would be tons of newbies who think "well if they can tolerate X amount of light then it should still be OK if they get only a little bit more." Perhaps there's always room for Jell-O, but there isn't always room for "a little" more light. So, even though plants technically can tolerate a little bit of light, the safest way to play it is no light at all during dark.
Gotcha. I would like to say that I did have a grow in a field by a somewhat popular road and when the cars turned they would get hit with some light for a sec. And they all turned out fine. But what you said makes a lot of sense. Thank you for clearing that up.
