Grow light. Ficus plant grown under a white LED grow light. A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue ...
Reflectors are often used in the lamps to maximize light efficiency. [32] At a medium growing density of 15 plants and 430 watts per square meter, electricity costs are not insignificant. [33] Plants or lights are moved as close together as possible so that they receive equal lighting and that all light coming from the lamps falls upon the plants.
Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [ 1 ] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [ 1 ] Some common choices of structures to house vertical farming ...
Hydroponics research mimicking a Martian environment uses LED lighting to grow in a different color spectrum with much less heat. Ray Wheeler, a plant physiologist at Kennedy Space Center's Space Life Science Lab, believes that hydroponics will create advances within space travel, as a bioregenerative life support system. [36]
In the first-ever partisan Cabarrus County school board race, four Republicans face four Democrats this November for four seats.. The race was made partisan by a bill passed by the Republican-led ...
Full-spectrum light is light that covers the electromagnetic spectrum from infrared to near- ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and atmospheric conditions.
