Thanks everyone for your responses... Here's the reason why I'm asking this: My locaton is approximately 25 degrees N latitude, so our winter season is VERY mild...

Let's say that a grower starts a plant at this time of the year (February). During vegging, that grower places his/her plant outside, then brings this plant inside at night to receive some low intensity fluros (better than nothing). This plant would be getting close to 20+ hours of light 7 days a week...In 2-3 months, we'd expect this plant to be a pretty decent size. If that grower wanted to flower his/her plant in May, when there is still roughly 13 hours of sunlight, would s/he HAVE to cover the plant, making sure that the plant is limited to 12 hours of light? Or would this 13 hours of light still allow the plant to flower, since early on in its life, the plant received 20+ hours of light?

I guess matters are complicated since the days are still getting longer in May, right? Anyways.....comments? Any other ways for this hypothetical grower to flower his/her plant without doing the very difficult task of covering the plant every night?

Once again, thank you!
knocks Reviewed by knocks on . My First Post! Question about flowering... OK, I've done a fair amount of reading over the last few years, but here's something I just started wondering: Most growers will veg anywhere from 18 to 24 hours a day, right? So if a plant has been getting 24 hours of light everyday, will it still flower at 12/12? As I understand it, MJ flowers since it "knows" that it will be dying soon with the coming winter, right? So does the full 24 hours of sun early in its life somehow trick the plant into flowering earlier.......with, say, 14 hours Rating: 5
