    Space gardens are advanced setups designed to grow plants in zero gravity using hydroponic or aeroponic methods. These systems provide nutrients through water mist or films, enabling plant growth without soil. They supply astronauts with fresh food, improve air quality and reduce supply loads from Earth. Studying space gardens helps scientists understand how plants respond to space conditions and supports long-term space missions and possible planetary colonisation.

    Vocational education focuses on developing practical skills and knowledge needed for specific trades and professions. It prepares students for real jobs through hands-on training, workshops and field practice. Instead of just theory, it emphasises doing and learning. It helps learners gain confidence, become self-reliant and secure employment in fields like farming, carpentry, nursing or IT. This education builds a skilled workforce and supports national development.

  3. Water pH influences how well plants absorb nutrients. In hydroponics, the ideal range is 5.5 to 6.5. If the pH is too high (alkaline) or too low (acidic), nutrients lock up and plants can’t use them. We can test the pH using pH strips or meters and adjust it using special pH up/down solutions to ensRead more

    Water pH influences how well plants absorb nutrients. In hydroponics, the ideal range is 5.5 to 6.5. If the pH is too high (alkaline) or too low (acidic), nutrients lock up and plants can’t use them. We can test the pH using pH strips or meters and adjust it using special pH up/down solutions to ensure healthy plant growth and nutrient availability.

  4. Wick-based hydroponics uses a cotton wick from nutrient solution to plant roots. DWC suspends plant roots in nutrient-rich, aerated water using an air pump. NFT runs a thin film of nutrient solution along plant roots in channels. All three systems support soilless growth and use minimal water, withRead more

    Wick-based hydroponics uses a cotton wick from nutrient solution to plant roots. DWC suspends plant roots in nutrient-rich, aerated water using an air pump. NFT runs a thin film of nutrient solution along plant roots in channels. All three systems support soilless growth and use minimal water, with NFT being more efficient but complex. These setups help in faster plant growth and space-saving farming.

  5. Start by soaking seeds overnight. Place them on a moist growing medium like jute mat or coco peat inside a shallow tray. Add water mixed with liquid nutrients. Keep the tray under sunlight or artificial light for at least 4–6 hours daily. Maintain proper water level and avoid overwatering. Within aRead more

    Start by soaking seeds overnight. Place them on a moist growing medium like jute mat or coco peat inside a shallow tray. Add water mixed with liquid nutrients. Keep the tray under sunlight or artificial light for at least 4–6 hours daily. Maintain proper water level and avoid overwatering. Within a week, healthy microgreens grow, rich in nutrients and ideal for garnishing or eating fresh.
