Abstract
A cultivation system for indoor farming of saffron plants (Crocus sativus) and other plants can include one or more compartments coupled with one or more climate modules which are controlled by one or more control systems. The control system can be configured to control the climate modules to provide different climate conditions to different compartments for different stages of the plants growth. Further, the temperature, humidity, and lighting in the compartments can include cyclic sequences configured to accelerate the life cycle of the plants. In addition, the plants can be trimmed, genome-specific fertilizer can be added to growth medium, absorbance pads can be used under the plant corms.
