I've grown one before, it didn't stretch very much tbh. Also, I didn't smell any lemon at all until after harvest, but then it got a really strong lemon flavor if not so much a lemon odor. Very similar to lemon haze I've had in the past. It yielded fairly well, if I remember correctly. It really depends on if you are under 600 watts of HPS or LED. If you don't mess up majorly, you should end up with 1 to 1.5 lb. If you have some experience, you are looking at 2+ lbs once you get things dialed in and learn how to maximize the productivity of your canopy.
