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. [35]
There is no substitute for light: if the amount of light received by the plant is insufficient, the plant will stretch, and / or growth will slow to a halt. For indoor gardening, one of the most important requirements is the amount of light energy striking the surface of the plant ("incident light"), which can be measured in lux (lux = lumens ...
The Lunar greenhouse is an underground farm made by Phil Sadles and Gene Giacomelli of the University of Arizona's Controlled Environment Agriculture Center (CEAC) [4] [5] The urine and exhaled air of the astronauts is reused in the system by the plants. [6] GreenForges is a Canadian startup developing underground farming systems. [7] [8] [9]
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 light, which generally appears pink to purple to the human eye).
1959 Movieland Drive-In Theater (consisted of cars, a drive in board with car spaces, a place to list "Featured Movies" along with blue and white double-bill cards that slid into the marquee; the "movie" was a film strip that projected by a battery operated light bulb onto a 4"x6" screen that attached to the drive in. Titles included Heckle and ...
On top of the gradual growth of the plant, the image reveals the true meaning of phototropism and cell elongation, meaning the light energy from the sun is causing the growing plant to bend towards the light aka elongate. Plant growth and development are mediated by specific plant hormones and plant growth regulators (PGRs) (Ross et al. 1983). [10]
