Cornelius entered the darkened greenhouse with mild interest on his features. He wasn't expecting Herbology as a class to be this...immersed in plant life. The ivy seemed to literally be coating all of the greenhouse walls around them, not helping the classroom's already dim lighting. Which seemed to be because of the ivy, or at least, that's what Cornelius gathered as the professor asked why there was so little light. He thought for a moment, remaining quiet as the rest of the students raised their hands to answer; seeming to have a lot of similarities in their ideas.

He agreed with a lot of their suggestions, but was inspired to think a bit more as Professor Bentley challenged them by mentioning that there was more to it than what everyone was saying. He raised his hand, hoping that he had come up with the right answer, though a bit unsure. "Is it...because of temperature as well?" he asked curiously, his eyebrows raising just a bit. "I mean, sunlight, yes, but...does the ivy thrive in a colder, more chilly climate...brought about by the lack of light?"
