Abrégé

A plant holder, provided with a growing substrate (20) for a plant to be cultivated therein, comprises a substantially liquid-tight casing (10) in which the growing substrate (20) is arranged. The casing (10) can be deployed from a relatively compact, particularly flat, starting state to a deployed state. The growing substrate (20) comprises an expanding material which, when hydrated, expands from a compact starting state to an expanded state. The casing (10) passes from the relatively flat starting state to the deployed state when the expanding material expands, and the expanding material (20) is provided with at least one seed (25) or germ of the plant. Such a holder is particularly intended for a cultivation facility with a cultivation layer in which the holder can be placed.

Abrégé

In a device a crop is cultivated in an at least substantially daylight-free environment, wherein the crop is exposed in an at least substantially fully conditioned cultivation space (10) to actinic artificial light from an array of artificial light sources (30) present in the cultivation space. During a cultivation cycle a power output of the artificial light sources (30) is adapted to an energy absorption of a part of the crop (50) illuminated thereby such that the crop close to each of the array of artificial light sources is subject to an at least substantially constant and at least substantially mutually equal vapour deficit.
