Our “808 FACTORY” business has been profitable for eight years since establishment of our first plant factory. Here, we present the business model of the brand that we have been operating. We discuss factory layout and operation management. We review measures of productivity per unit cultivation area, per unit of electric energy consumption, per labor hour and merchantability/commercialization ratio. We also outline control of variables such as temperature, photoperiod, airflow, CO2 and nutrient supply.
