It describes crop yield and its underlying processes; radiation, greenhouse cover, and temperature; the properties of humid air and the physics of air treatment; ventilation and mass balance; crop transpiration and humidity in greenhouses; crop response to environmental factors; heating in climate-controlled greenhouses; cooling and dehumidification; supplementary lighting
; carbon dioxide supply; managing the shoot environment; root zone management; and vertical farms.
The ElectroniCast definition of General Lighting also includes directional and supplementary lighting
This research aimed to analyze Girolando calves' concentrate intake and performance placed in individual shelters with distinct roofing materials and programs of supplementary lighting
during milk-feeding stage.
It was also considered, in the experimental arrangement, the combination of types of roofs with the different light time programs promoted by supplementary lighting
: natural light + 4 h of supplementary lighting
(16 h light); natural light + 8 h of supplementary lighting
(20 h light) and natural light (12 h light).
However, 20 fc are sufficient for ambient light in most occupancies and supplementary lighting
could be obtained from daylight and personalized dimmable LED task lights.
Many deer collisions happen at dawn or dusk; supplementary lighting
can only help.
Climate-controlled greenhouses, like Village Farms International, Inc., GATES[TM] greenhouse, are already producing more than 850,000 lbs of vegetables per acre per year, and supplementary lighting
will increase that to one million lbs per acre per year.
The vegetable plants were grown to harvest time in a greenhouse under daylight with supplementary lighting
provided by standard high-pressure sodium lamps.
Three different lighting modules are available, as well as a supplementary lighting
module where extra illumination is required.
The Future Garden used supplementary lighting
, artificial plants and turf, with vegetables grown in a greenhouse using UV screens and edible fish kept in the garden pond.
I do not mean rigging up supplementary lighting
systems and all that, but providing the right soil, level of nutrients and water.
