Overgrow is a term used to describe a situation where plants, particularly weeds, grow excessively in a given area, often outcompeting other vegetation. This phenomenon can occur in gardens, agricultural fields, or natural ecosystems, leading to reduced biodiversity and crop yields. In the context of cannabis, "Overgrow" can also refer to a movement aimed at promoting the cultivation of marijuana for personal use and advocating for its legalization. This initiative encourages individuals to grow their own plants, emphasizing the benefits of self-sufficiency and the importance of plant-based medicine.
