A short promotional film containing time-lapse photography for Swift & Company's commercial lawn fertilizer, Vigoro.
This film displays two potted tomato plants growing side-by-side in soil that is described by Ott's narration as, "deficient in plant food elements." Ott indicates that the soil belonging to the plant on the left has been supplemented by the completely balanced plant food, Vigoro. Subsequent time-lapse photography documents significantly greater growth and appearance in the Vigoro-fed tomato plant compared to its neighbor on the right. The song, "Cascade," performed by the Royal Artillery Orchestra accompanies the time-lapse photography.
Ott regarded this film as clear evidence of the importance of variations between daytime and evening temperatures toward soil stimulation and plant growth. In Ott's autobiography, My Ivory Cellar: The Story of Time-Lapse Photography, he remarks that because approval for this film project was not granted until the hot summer had already commenced, "To my surprise, there was no noticeable difference in the growth between the two plants being photographed...This experiment was started over again several times, but it was not until fall when the weather and temperature in my greenhouse was considerably cooler that a noticeable difference between the fed and unfed plants was evident. Then the difference was so great that it was almost unbelievable."
