A carrier tray for carrying multiple plant pots includes a plurality of sockets for receiving plant pots, where the sockets include a first set of planar areas, arranged alternately and with a second set of planar areas, with a concertinaed section provided between each planar area of the first set and of the second set. The first set of planar areas are of variable geometry and can be urged from a first, kind angle to the vertical when the socket is unfulfilled, to a second, smaller angle to the vertical when a pot is inserted into the socket.

The disclosure relates to a stackable grow box and a modular grow box system. The stackable grow box (10) comprising an upper part (20), a middle part (30) and a lower part (40), wherein the lower part (40) comprises a tray to carry plants or insects to be grown in the box, the middle part (30) interlinking the upper part (20) and the lower part (40). The upper part (20) and the lower part (40) comprise corresponding fluid coupling means configured to provide an automatic fluid coupling when an upper grow box (10) is arranged on top of a lower grow box (10). The box further comprises fluid handling means configured to dispense fluid received from the fluid coupling means of the upper part (20) to the plants or insects in the tray and for collecting excess fluid from the tray and passing it to the fluid coupling means of the lower part (40).

A support platform for holding bucketed plants includes a top and an opposed bottom, a sidewall extending therebetween, and a reservoir bounded by the sidewall. Seats formed into the top, the seats defining depressions shallowly recessed below a top surface. A channel extends between the seats, the channel shallowly recessed below the top surface, and the channel joining the seats in fluid communication with each other. A drain is in the channel and is configured to drain fluid from the channel into the reservoir bounded by the sidewall.

A method of increasing interspace among plant containers. The method comprises: providing a set of plant containers, the set comprising first and second plant containers; arranging the first plant containers in a first structured grid formation along a horizontal plane; and arranging the second plant containers in a second structured grid formation along said horizontal plane, whereby when viewed from above the first and second plant containers are alternatingly arranged in a joint structured grid formation in a first area. The method comprises, for increasing the interspace among the plant containers, mutually simultaneously moving the second plant containers in their second grid formation away from the first plant containers in a vertical direction and subsequently placing the second plant containers in a second area.
