Try it..ive read something like that to..but never tried it. I know it has to be an opaque bag but needs to still breathe.

You can sex a branch by covering it so it gets 12 hrs of dark for sure. dunno bout just 1 leaf, my gut feeling is no but i could be wrong.

i agree with the cat
i dont think its gonna work, mary janes got too many leaves its just gonna forget about that one 'retarded' leaf that is in another dimension of darkess

iv heard about it before just never really believed it would work.

It works on a branch, need more than one fan leaf.

Wow. I have NEVER heard that. Well, not until now.
Just fukcing with one leaf is not going to hurt the whole plant. At least, that seems like it shouldn't happen. I mean, that would be a crappy mechansim for a plant to have, right? I mean, if damage to one leaf can hurt a whoel plant, then really, no plants would ever survive, would they?
But in the interest of science, why not just try it out on one of your plants? I mean, it's certainly an intersting thing to think about and if it does happen, then you've learned somethign imporatnt.
Of course, I'd rather someone else try it out than having it screw up my harvest. LOL
Your professor is a bullshit artist. Saying something hes heard that someone said that... Misinformation. One leaf is not going to "induce flowering" (for the whole plant), we know that. If one leaf gets covered up in nature, maybe by a competing plant, suddendendly your plant can't veg anymore and has to flower. Doesn't make evolutionary sense.

Ya im thinkin that this professor is NOT a bullshit artist, especially since he teaches at UCBERKLEY.. And have you ever tried it? I didn't think so... I am sure he knows more about plant biology then you, the professor I'm speaking of is in the vid i posted before this one

when I was younger I grew outside, and I would use a cardboard tube from a paper towel roll and slide it over a lower branch , in two weeks that branch and only that branch would show its sex . I would do this around June and if it was a male I'd schwack it down.No seeds and no wasting time, water,effort...ect. worked every time.Simple,easy,cheap and fast.

Look back on darwin for your answer.
As a plant matures, and size, shape, and foliage increase, lower leaves start to fall off and die. The process is exponentially faster if the leaf gets inadequate light, and the plant focuses more energy on canopy leaves.
If you COMPLETELY shade one leaf, odds are the plant is just going to shed it.
If you cover INTERNODES, then they will flower. But just covering a leaf wont do shit.
If anyone here has a copy of cervantes's book on gardening, theres an image with a little passage showing a large outdoor plant, where half of the plant got darkness at night and flowered, and the other half got light from a regular street lamp, and remained in veg the entire time.
From this example you can see that the plant only flowers the INTERNODES that get darkness.
Sorry, but I'm saving you some time and energy trying to kill one large fan leaf.

if it was covered by another plant's leaf, it's not full darkness so it probably wouldn't work. i can't say i've ever put a single leaf or branch in a black box or cloth to provide full darkness, but i see how it could work. the plant produces it's flowering hormone when it's dark, so causing a single leaf to produce that same chemical all day, could fool the plant into flowering. my concern would be that it may cause the plant to turn hermie cuz of stress. i was also thinking that when my plants lower leaves stop getting light, they turn yellow and fall off eventually. so perhaps if you were to cover that individual leaf for most of the day, but give it a couple hours to get light to prevent the yellowing, it could have a chance.
