As a result of the serious natural changes we are experiencing, the subject around ecology has gained interest, and the need for environmental preservation is driving significant efforts to reduce ecological footprints. This has resulted in a considerable trend toward the handling of eco-friendly devices that use resources in a sustainable manner. The concept of SmartEnvi, which includes SmartFlora Technology (SFT), is an innovative and complex system for the future of urban gardening and microclimates that integrates smart technologies and sustainable practices to develop optimal life care solutions and transform urban areas into green smart environments (GSEs). The integration of Linear Programming (LP), Graph Theory (GT), and Discrete-Time PID Controllers (DT-PID) should lead to enhanced plant growth and reduced resource consumption. Based on anticipated results, SmartEnvi has the potential to significantly expand smart plant care by innovatively merging technology and sustainability.
