Cultivating vegetables using a hydroponic system is no longer something new. Many types and models of hydroponic installations have been implemented by farmers. One of the most popular types of hydroponic systems is Deep Flow Technique (DFT). This hydroponic system has several installation models that vary the height between pipes, generally according to the available land. A pyramid-shaped installation is a hydroponic model that has advantages because of its high pipe arrangement. This research aims to determine the influence of differences in height between pipes and directions in the DFT system pyramid hydroponic installation on the growth of green lettuce (Lactuca sativa L). The research was carried out at the SITH Haurgombong Research Garden in December 2022. The research used a Randomized Block Design (RAK) consisting of 8 treatments with different heights and directions of hydroponic pipes with 8 repetitions, namely as follows: A (50 cm, west), B (50 cm, east), C (90 cm, west), D (90 cm, east), E (130 cm, west), F (130 cm, east), G (170 cm, west), and H (170 cm, east ). Growth data in all treatments were tested using Analysis of Variance (ANOVA) and Duncan Test with ?=0.05. This research concluded the differences on height and direction in the DFT system pyramid hydroponics affected plant height, number of leaves, leaf length, fresh plant weight, dry plant weight, and dry shoot-root ratio of green lettuce (Lactuca sativa L) in treatments G and H; leaf width in treatments F, G, and H; the longest root length in treatments A and F; while the wet shoot-root ratio in treatments A, D, and E.
