Phytotrons are culture chambers used by researchers in which ambient parameters such as temperature, humidity, irrigation, electrical conductivity of the nutrient solution, pH, lighting and CO2 are finely controlled. In addition, these installations make it possible on the one hand to measure the impact of environmental changes, and on the other hand to optimize the growth of plants in artificial growing conditions. Thanks to the democratization of hardware, cloud computing and the new possibilities offered by the Internet of Things (IoT), it is now possible to build a personal phytotron at an affordable cost. In this article, we propose to use connected objects to develop a personal growth chamber in order to produce fresh vegetables in an urban context.
