Nope, your plant will become totally hermied out in the final week it has to live and become worthless.
Probably hundreds of male flowers forming as we speak spewing pollen on the plants and walls. No doubt you will never be able to
use that room again without getting a ton of seeds.
You'll need to wipe down walls with a mixtures of peroxide and and concentrated acetic acid, possibly even flame sterilize with alcohol.
That will teach you to use a cheap timer.
