Abstract
In this study, the thermal, energy, economic, and environmental perspectives of a smart Cannabis plantation are investigated. A commercial R-32 air conditioning at a cooling capacity of 12,300 BTU/h is implemented for the 5-lighting sets. One 300 We-violet-light-emitting diode (LED) and two 100 We-daylight-LEDs are designed for one lighting set at a photosynthetic photon flux density of 100 µmol/m2⋅s. A smart watering system is designed to automatically control a watering period of 62 h, an operating time of 40 min, and a watering rate of 41.5 L/time. The smart Cannabis plantation can produce a fresh inflorescence of 250 g and a dried inflorescence of 46.3 gdy, respectively. A power consumption of 126.9 kWh/plant is mainly driven the environmental impacts of a climate change of 6.22E+02 kg CO2 eq/kgdy. The economic result of a levelized cost is approximately 262.85 USD/kgdy.
