Can this plant be saved?

It seems like I made a gardening mistake. Will this plant recover? Or do I need to replant? I used a NewAir EC-111W Evaporative Cooler for ventilation and to help control temperature and humidity.

I was compensated monetarily for including the evaporative cooler in this video.
