Passive income: NO

Starting an AI Smart Greenhouse Automation Service has the potential to generate passive income, but achieving full automation and passive earnings may not be common for most individuals. Setting up automation systems and outsourcing tasks like maintenance and monitoring can help in making the business more passive. However, reaching a fully passive income level typically requires a significant initial investment in technology, infrastructure, and ongoing maintenance. While some individuals may share success stories of earning passive income from this type of service, it is more common for active involvement to be necessary to ensure optimal functioning and profitability. Therefore, while passive income is achievable in this business, it may not be easily attainable for the majority of participants without ongoing active management.
