Tikhov's research into astrobotany would later develop into research into growing plants in space, or demonstrating the possibility of plants to grow in extraterrestrial conditions (especially comparing the climate of Mars and Siberia), but he was the first known astronomer to use color to attempt to measure the level of vegetation on an ...
Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens.

The organisms require nutrient-rich water with temperatures between 6 and 14 °C (43 and 57 °F). They are known for their high growth rate—the genera Macrocystis and Nereocystis can grow as fast as half a metre a day (that is, about 20 inches a day), ultimately reaching 30 to 80 metres (100 to 260 ft).

Macrocystis pyrifera is one of the fastest-growing organisms on Earth. [23] [24]: 8 They can grow at a rate of 60 cm (2 ft) a day to reach over 45 m (150 ft) long in one growing season. [8] [25] [26] Juvenile giant kelp grow directly upon their parent female gametophyte. To establish itself, a young kelp produces one or two primary blades, and ...
A Veggie module weighs less than 8 kg (18 lb) and uses 90 watts. [7] It consists of three parts: a lighting system, a bellows enclosure, and a reservoir. [8] The lighting system regulates the amount and intensity of light plants receive, the bellows enclosure keeps the environment inside the unit separate from its surroundings, and the reservoir connects to plant pillows where the seeds grow.
Many plants lose much of the remaining energy on growing roots. Most crop plants store ~0.25% to 0.5% of the sunlight in the product (corn kernels, potato starch, etc.). Photosynthesis increases linearly with light intensity at low intensity, but at higher intensity this is no longer the case (see Photosynthesis-irradiance curve). Above about ...
But grow lights or even simple LED strip lights are great options, too, if you don’t have a ton of windows. Also, avoid placing any plant in front of drafty windows or heating vents, says Hancock.
The future ALINA lunar lander will carry a small "biosphere" cylinder called Lunar Plant Growth Experiment (LPX), where NASA will attempt to germinate and grow several plant types. [ 19 ] [ 20 ] The EDEN-ISS project was a 4 year project in Antarctica at Neumayer Station III designed to showcase plant cultivation system for future tests on-board ...
