The existence of a space farm would aid the creation of a sustainable environment, as plants can be used to recycle wastewater, generate oxygen, continuously purify the air, and recycle feces on the space station or spaceship. [2] Just 10 m 2 of crops produces 25% of the daily requirements of 1 person, or about 180-210 grams of oxygen. [3]
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.
The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.
Wisconsin Fast Plants were initially developed as part of a larger breeding project of Rapid-Cycling Brassicas, originating in the early 1970s. [1] Wisconsin Fast Plants and other Rapid-Cycling Brassicas were selected through conventional plant breeding to be a tool that would speed up genetic research for disease resistance in economically important Brassica crops.

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. [1]
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).
6 H 2 O + 6 CO 2 + energy → C 6 H 12 O 6 + 6 O 2 where C 6 H 12 O 6 is glucose (which is subsequently transformed into other sugars , starches , cellulose , lignin , and so forth). The value of the photosynthetic efficiency is dependent on how light energy is defined – it depends on whether we count only the light that is absorbed, and on ...
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
