Summary We present a simple and effective high‐throughput experimental platform for simultaneous continuous monitoring of water relations in the soil–plant–atmosphere continuum numerous plants under dynamic environmental conditions. This system provides simultaneously measured, detailed physiological response profile each plant array, over time periods ranging from few minutes to entire growing season, normal, stress recovery conditions at any phenological stage. Three probes pot array specially designed algorithm enable water‐relations characterization whole‐plant transpiration, biomass gain, stomatal conductance root flux. They also quantitative calculation whole water‐use efficiency relative content high resolution soil atmospheric The has no moving parts can fit into many environments. A screening 65 introgression lines wild tomato species ( Solanum pennellii ) crossed with cultivated S. lycopersicum ), using our conventional gas‐exchange tools, confirmed accuracy as well its diagnostic capabilities. use this method is discussed light gaps understanding genetic regulation performance, particularly abiotic stress.
