A propagation system (100) comprising a propagation frame (200) and a propagation trolley (300) is disclosed. The propagation frame comprises carrier structures (210) each including at least one lighting element (220) and/or at least one liquid dispensing element (230). The propagation trolley comprises support structures (320) each being adapted for supporting at least one propagation tray (370) or group of plants. The support structures and/or the carrier structures have free ends allowing the support structures to be inserted between carrier structures by a mutual movement of the propagation trolley and the propagation frame such that the carrier structures and the support structures are positioned alternatingly in a vertical direction. A method for propagation of plants includes inserting the support structures between carrier structures, and supplying each of the propagation trays or groups of plants with light emitted from at least one lighting element and with liquid dispensed from at least one liquid dispensing element on a carrier structure.L'invention concerne un système de propagation (100), lequel système comprend un bâti de propagation (200) et un chariot de propagation (300). Le bâti de propagation comprend des structures porteuses (210) comprenant chacune au moins un élément d'éclairage (220) et/ou au moins un élément de distribution de liquide (230). Le chariot de propagation comprend des structures de support (320) aptes chacune à supporter au moins un plateau de propagation (370) ou un groupe de plantes. Les structures de support et/ou les structures porteuses ont des extrémités libres permettant aux structures de support d'être insérées entre des structures porteuses par un déplacement mutuel du chariot de propagation et du bâti de propagation, de telle sorte que les structures porteuses et les structures de support sont positionnées en alternance dans une direction verticale. L'invention concerne également un procédé de propagation de plantes, le
