Short Day Plant
Short day plant explained in an easy to understand way:
Imagine trying to watch your favorite TV show, but it only airs when it's dark outside. Just like you waiting for nighttime to catch your show, a short day plant needs more than 12 hours of darkness to initiate flowering. The TV show represents the flowering process, and the nighttime is like the required period of darkness; both need the right conditions to start.
