An integrated plant cultivation system for enhancing plant cultivation efficiency in controlled environments or agricultural facilities may incorporate a growth-inducing light source. The system may include a versatile rack assembly for multi-level plant cultivation with boxes on each level. The boxes may contain incubation chambers for plant growth. An irrigation system may connect to the incubation chambers, providing water and nutrient solutions tailored to each chamber's unique nutrition needs. The system may also include a drainage management system to recover excess water and nutrients, promoting sustainability. In addition, the system may further include a ventilation sub-system configured to provide ideal atmospheric conditions within the incubation chambers. The system may further comprise a controller configured to oversee the growth-inducing light source and environmental parameters in each chamber, optimizing plant development according to their specific growth stages and requirements.
