A system for adjusting one or more settings of one or more identified light sources for horticulture growth of plants or crops, comprising: at least one input interface; at least one control interface; and at least one processor configured to: - use said at least one input interface to receive input from one or more sensors (21-23,26-28,89); determine, from said input, an attention area of an operator (81,83) where performance of an operator task on or related to one or more plants or crops is needed; identify one or more light sources illuminating said attention area; and use said at least one control interface to adjust one or more settings of said one or more identified light sources from grow light settings for growing the plants or crops to operator light settings for performing the operator tasks; the system being characterised in that the at least one processor is further configured to: - use said at least one input interface to receive further input from said one or more sensors (21-23,26-28,89) and/or one or more further sensors; determine, from said further input, that no further attention by said operator (81,83) is needed in said attention area; and use said at least one control interface to adjust said one or more settings of said one or more identified light sources from said operator light settings to said grow light settings or to new grow light settings upon determining that no further attention by said operator is needed in said attention area; - wherein the at least one processor is further configured to determine a duration of use of said operator light settings; and determine said new grow light settings and/or a period during which said grow light settings or said new grow light settings need to be used after applying said operator light settings based on said grow light settings, said operator light settings and said duration. at least one input interface; at least one control interface; and at least one processor configured to: - use said at least one input interface to receive input from one or more sensors (21-23,26-28,89); determine, from said input, an attention area of an operator (81,83) where performance of an operator task on or related to one or more plants or crops is needed; identify one or more light sources illuminating said attention area; and use said at least one control interface to adjust one or more settings of said one or more identified light sources from grow light settings for growing the plants or crops to operator light settings for performing the operator tasks; - use said at least one input interface to receive input from one or more sensors (21-23,26-28,89); determine, from said input, an attention area of an operator (81,83) where performance of an operator task on or related to one or more plants or crops is needed;

- wherein the at least one processor is further configured to determine a duration of use of said operator light settings; and determine said new grow light settings and/or a period during which said grow light settings or said new grow light settings need to be used after applying said operator light settings based on said grow light settings, said operator light settings and said duration. - use said at least one input interface to receive further input from said one or more sensors (21-23,26-28,89) and/or one or more further sensors; determine, from said further input, that no further attention by said operator (81,83) is needed in said attention area; and use said at least one control interface to adjust said one or more settings of said one or more identified light sources from said operator light settings to said grow light settings or to new grow light settings upon determining that no further attention by said operator is needed in said attention area; - wherein the at least one processor is further configured to determine a duration of use of said operator light settings; and determine said new grow light settings and/or a period during which said grow light settings or said new grow light settings need to be used after applying said operator light settings based on said grow light settings, said operator light settings and said duration.
