I don't think Light leaks or being a few minutes late to turn off the lights will cause seeds to produce. the amount of sunlight changes throughout a whole outdoor grow. moonlight has to have more of a light leak than any light under a door crack. My theory on why people get seeds in a female plant is that either it hermed, or that it got pollen on the plant from another source. What I think alot of people might overlook is that we all smoke. some of us (including myself) roll our own joints or pack our own bowls with weed that has seeds and then gotta check out the plants. then transfer pollen from the bagweed to the plants. just a theory tho. either way you'll be smokin that muzzachunka soon. nice buds man
