greenhouse working model 3d science project diy howtofunda agriculture farming model

hydroponic farming working model, in this course introduces learners to modern soilless farming techniques, where plants are grown using nutrient-rich water solutions instead of traditional soil. The course explains the scientific principles behind hydroponics, including nutrient absorption, water circulation, and oxygen supply to plant roots. Students explore different hydroponic systems such as nutrient film technique (NFT), deep water culture, and drip irrigation, understanding how each system supports efficient plant growth. By constructing and testing a working model, learners gain hands-on experience in setting up the structure, arranging water pumps, preparing nutrient solutions, and maintaining optimal conditions for crops. The course highlights the advantages of hydroponics, such as faster growth rates, higher yields, water conservation, and year-round cultivation, making it an eco-friendly and sustainable solution for future agriculture. It is ideal for science projects, school exhibitions, and anyone interested in innovative farming, sustainability, and food security technologies. howtofunda
