Abstract

Farming is an essential way of gathering food for humanity, and has been altered over the years thanks to technology. Throughout the past couple of decades, different methods of farming have been created, such as hydroponics and aeroponics. Aeroponics is the process of misting the roots of the bulb, seed, bud, etc., in order to give the plant the nutrients it needs to grow. The purpose of this experiment was to determine the best root temperature range in which to grow plants aeroponically. It was hypothesized that the bulbs with the highest root temperature would have the longest root length based on the fact that plants tend to thrive in slightly higher temperatures than 21°C . Three aeroponic devices with water temperature settings of 13, 21, and 31 degrees Celsius were used to allow the Muscari bulb to remain suspended in the air while still receiving necessary nutrients from the mist. The two temperature groups, 21°C and 31°C, were shown to support the hypothesis that the bulbs with the highest root temperature would have the longest root length [F(2,9) = 9.1, p=.00015] and [F(2,9 ) = 6.7, p=.0015]. The group held at a temperature of 13°C did not show a significant difference in growth [F(2,9) = .752, p=.47]. Therefore, the bulbs grown in colder temperatures had a more negative impact on the root growth, and the warmer and neutral temperatures had a more positive impact on the growth.
