In the video, a man is standing in front of a row of plants. He is wearing a black shirt with the words "R & H Hort" written on it. The man is speaking to the camera, and there are subtitles at the bottom of the screen that read "The water and nutrients flow by gravity to a in the middle of the row, down there." He continues to speak and the subtitles change to read "The plants take what nutrients they want, and don't want it gets recycled round and round." The man is gesturing with his hands as he speaks, and the plants behind him are green and leafy.
