This method reduces water and fertiliser usage while eliminating the need for pesticides.<\/li>\n<li><strong>Soil-like Media<\/strong>: Mimics terrestrial soil to support plant growth, often supplemented with slow-release fertilisers.<\/li>\n<\/ul>\n<\/li>\n<li>The <strong>\u2018Veggie\u2019 system<\/strong> aboard the International Space Station (ISS), a space garden about the size of a carry-on bag, exemplifies these approaches.<\/li>\n<\/ul>\n<h2><strong>ISRO\u2019s Experiment with Lobia<\/strong><\/h2>\n<ul>\n<li>ISRO\u2019s CROPS module functioned as a miniature greenhouse, simulating Earth-like conditions in space:\n<ul>\n<li><strong>Medium<\/strong>: Highly porous clay pellets were used, retaining water and providing nutrients via slow-release fertilisers.<\/li>\n<li><strong>Light<\/strong>: Eight LEDs (four warm, four cool) simulated a 16-hour day and an 8-hour night for photosynthesis.<\/li>\n<li><strong>Temperature and Atmosphere<\/strong>: Conditions were regulated between 20\u201330\u00b0C, with Earth-like air composition.<\/li>\n<li><strong>Water Delivery<\/strong>: An electric valve controlled from Earth injected water into the soil-like medium.<\/li>\n<\/ul>\n<\/li>\n<li>The seeds germinated on the fourth day, with leaves emerging a day later, demonstrating the success of the experiment.<\/li>\n<\/ul>\n<h2><strong>Ideal Space Crops<\/strong><\/h2>\n<ul>\n<li>Plants are chosen based on their growth efficiency, nutrient content, and adaptability to confined environments.
