Abstract

The study was designed to assess whether the addition of grass clippings to
hydroponic lettuce systems would benefit them. Initially, a seed tray filled with coco peat was used to hold the lettuce seeds. However, they received water and a special lettuce combination, which was essential to their development. The seedlings were put in a still water hydroponic system once they reached the appropriate size. The pH readings, electrical conductivity (us/cm), and total dissolved solids (PPM) were the main factors that the researchers monitored. After 23 days (about 3 and a half weeks), the lettuce plants were transferred to a Flowing Deep-water culture. The researchers measured the plant's length, width, pH, and nutrient concentration on a weekly basis. They discovered after analyzing all the data collected throughout the experiment that there were no significant differences between the two variables: hydroponic systems with grass clippings and Epsom salt (treatment group) and hydroponic systems without any additional nutrient source (control group).
