Make money online: YES

Vertical farming setup and smart agriculture technology integration can be a remote-friendly side hustle as most of the work can be done online. However, there might be some in-person requirements for setting up the physical farm infrastructure initially. People on forums like Reddit and Twitter generally find this business opportunity promising, especially in terms of sustainability and innovation. The success of this side hustle may depend on your location for access to clients and suitable climates for farming. It's crucial to consider time zones for communication with clients and ensure you have the necessary equipment for farming and integrating smart technologies. Setup costs for vertical farming can range from $10,000 to $50,000, and it may take around 6 months to start seeing profits.
