The image displays an exterior view of a greenhouse structure located in Na Sangkham, Laos. The foreground features the side wall of a long, tunnel-like greenhouse, extending from the lower left towards the upper right. The upper portion of the wall and the unseen roof are covered with translucent, weathered white plastic sheeting, supported by an internal framework of metal or light-colored beams. Below this, the middle section of the wall consists of a fine mesh screen, heavily stained with vertical streaks of green algal or moss growth. Through this mesh, rows of white horizontal pipes or channels, consistent with a hydroponic cultivation system, are visible inside the greenhouse. Young, green leafy plants are discernible growing within these channels. The lower section of the greenhouse wall, visible beneath the mesh, appears to be constructed from vertical, light-colored slats or panels. To the immediate left of the greenhouse, a narrow, slightly elevated concrete or paved edge runs parallel to the structure. Below this edge, a strip of uncultivated ground or a shallow ditch is filled with various green weeds and a distinct fern plant. The scene is brightly lit by ambient daylight, and no individuals are present.
