Description: Growing strawberries in a controlled environment can be difficult during winter months when lighting hours are low. Cultivation is further compromised when low light conditions promote irregular growth, often resulting in reduced fruit quality. In this study, the internal light environment of strawberry cultivation in a greenhouse was monitored and characterized to better understand strawberry growth response. A total solar radiation (RAD) sensor and a photosynthetic photon flux (PPF) sensor were installed at the center of the test greenhouse and at five additional points (east, west, north, and south). Data were collected at 10 minute intervals over a period of four months during winter (?20.11~?21.2). A light distribution diagram was prepared based on the greenhouse dimensions to demonstrate uniformity and transmittance. Results from the two sensors showed high distribution at the south point and low distribution at the north point. The rate of decrease in RAD averaged at 54%, with the rate of decrease in PPF averaging 61%. This variance showed a significant decrease in the amount of light entering the greenhouse during winter months. The uneven light distribution in the test greenhouse resulted in the location being deemed unsatisfactory for strawberry growth. Therefore, supplemental lighting is needed to improve the environment for efficient strawberry cultivation. This study was supported by the 2021 RDA Fellowship Program (Project number PJ01510402) of the National Institute of Agricultural Sciences, Rural Development Administration, Republic of Korea.
