Canopydew: Greenhouse Lab

Canopydew is a commissioning bench for greenhouse climate: it documents measured climate changes around recorded interventions, with baseline and response windows that a grower can review. Temporal association does not establish that an intervention caused a change. Synchronized air-temperature traces from several sensor positions share one scrubbable chart, interventions are marked on the timeline, and the psychrometric arithmetic underneath (saturation vapor pressure, dew point, leaf VPD, daily light integral) follows the FAO equation basis, with methodology links readable inside the app. A session opens on a bundled synthetic example, the Ridge vent response check: 72 observations from three mapped sensors in a propagation house, with one ridge-vent intervention. Scrub the trace to compare positions, then set baseline, response, and recovery windows in the Evidence workspace;…
