Abstract

L'invention concerne un appareil de culture de plantes pouvant comprendre une armoire comprenant une chambre de culture dans laquelle au moins un lit est disposé et des plantes sont cultivées, un capteur de détection d'eau résiduelle configuré pour détecter si l'eau résiduelle de l'eau d'alimentation fournie au lit est présente, une pompe à eau configurée pour pomper de l'eau dans un réservoir d'eau vers le lit, une vanne de trajet d'écoulement configurée pour être ouverte pour fournir l'eau pompée par la pompe à eau au lit, et un dispositif de commande configuré pour mesurer un temps de rétention d'eau qui est une période de temps pour laquelle l'eau reste dans le lit à partir d'un moment où l'alimentation en eau du lit est achevée lorsqu'une opération d'alimentation en eau est effectuée sur le lit et détecter la survenance d'une erreur lorsque le temps de rétention d'eau est inférieur à un temps prédéterminé.
