Uhhm.. Sorry to say, but your plant has 0 "flowering weeks"
You could definitely build a greenhouse around it to try and keep out the cold. Stem looks pretty strong, so don't think a lack of wind will be a problem.
- What you can do to make her flower, is wait I guess.. That or figure out a way to seal off the greenhouse, so you can completely darken it for 12 hours a day.. That should make her start flowering.
