Etiolation is a process in flowering cannabis plants grown in the partial or complete absence of light. It is characterized by long, weak stems; smaller leaves due to longer internodes; and a pale yellow color (chlorosis). Etiolation aims to increase the chances of root initiation.
In botany, etiolation /iːtiəˈleɪʃən/ is a characteristic of flowering plants (angiosperms) grown in partial or complete absence of light. It is characterized by long, weak stems; smaller leaves due to longer internodes; and a pale yellow color (chlorosis). The development of seedlings in the dark ("skotomorphogenesis") leads to etiolated seedlings.
