Systems and methods for increasing a user's task performance and personal wellbeing resulting from caring for indoor plants are disclosed. Internet-of-Things sensors and devices monitor measurements relating to environmental factors and a user's care patterns associated with designated indoor plants. User-performance sensors and devices measure the user's wellbeing and the user's task performance, both in caring for the plants and in other productivity-driven tasks. Recommendations for the plant care and prescriptions for the users are generated using machine-learning models and provided to the user through notifications to alter the user's behavior in a desirable way, both in plant care and in real-world task performance.

A grow light includes a plurality of cool white LEDs, a plurality of warm white LEDs, and a driver electrically coupled to the cool white LEDs and the warm white LEDs. An intensity level and spectral composition of the radiant energy emitted by the grow light may be tuned or configured by varying a ratio of the quantity of cool white LEDs to the quantity of warm white LEDs, by varying a spatial arrangement among the cool white LEDs and the warm white LEDs, or by varying a level of current provided to some or all of the cool white LEDs and the warm white LEDs.

Produced PAR neither replicates the spectral bandwidth of sunlight at the surface of the earth, nor the absorption spectrum of green plants, nor the absorption spectrum of photosynthetic processes, but—based on discovery that PAR at only a number of unique wavelengths is optimally energy-efficient to promote normal or better plant growth—instead desirably concentrates PAR emissions in a limited number, preferably about nine (9), narrow bands. Narrowband, even extremely narrowband, radiation is preferred at 430 and 662 nanometers wavelength (first and second absorption peaks of chlorophyll A); 453 and 642 nanometers wavelength (first and second absorption peaks of chlorophyll B); and still other wavelengths (only). Preferably more than 50% of the total PAR flux is within a total bandwidth of less than 160 nanometers wavelength in the range between 360 and 760 nanometers wavelength, and more preferably 90% of the PAR flux is within a total bandwidth of less than 80 nanometers wavelength within this range. When the intensity of the PAR flux in these narrow bands is, as is preferred, only but that occurring within the normal solar spectrum, then tremendous energy savings are innately realized in production of the new-spectrum PAR, ranging to ¾ and more from previous PAR. Moreover, the new-spectrum multi-narrow-band PAR is electrically efficiently produced using narrowband-emission LEDs.
