You can definitely bend that bad girl over. As stated before, if the stalk breaks it should still survive. I usually wrap the effected area with electrical tape. You could try hanging a light weight from her to continue a steady bend on her.

You really don't have to worry about light pollution outside. Unless you have a bright security light right over the top of it or some such thing then the light will be diffused before it effects the plants budding. You should see discernible buds any time now. Harvest should be around Sept 15 - Oct 15.

I think your big problem is going to be odor once she starts to bud up. I hope your neighbors are either cool of ignorant because there really isn't much you can do about that.

Best of luck
