Which factor is not recognized as influencing the growth of cannabis plants?

The growth of cannabis plants is influenced by several critical environmental and biological factors, among which genetics, soil pH, and light exposure play significant roles. Genetics determines the inherent traits of the cannabis strain, including growth rate, yield, and resistance to diseases. Soil pH affects nutrient availability and uptake; if the pH is too high or too low, it can hinder the plant's ability to absorb essential nutrients. Light exposure is crucial as cannabis plants require a specific light spectrum and duration to optimize photosynthesis and growth stages.

In contrast, the availability of social media does not have a direct impact on the biological processes or physical environmental factors that contribute to the growth of cannabis plants. While social media can influence market trends, consumer education, and awareness about cannabis, these factors do not affect the cultivation or physiological development of the plants themselves.
