The oxygen concentration in the nutrient solution is extremely important for the health and development of plants, including lettuce. Lettuce plant roots perform respiration, a process through which they absorb oxygen and release carbon dioxide. This metabolic process is essential for providing the energy necessary for growth and optimal plant functioning. An adequate oxygen concentration in the nutrient solution is crucial for the roots to efficiently carry out this process. Insufficient oxygen concentration can lead to inefficient nutrient absorption, thus affecting plant growth and development. The purpose of this paper is to investigate the impact of different lettuce varieties and cultivation technologies on the average plant mass, length, and average root volume. It examines how various growth conditions, such as additional oxygenation and LED lighting, influence the development of lettuce plants, especially the Lugano and Carmesi varieties. By evaluating these factors, the paper aims to provide relevant information for optimizing agricultural practices in lettuce cultivation, with the goal of maximizing production and crop quality.
