The shared garden landscape design for urban residential areas aims to address the challenges of urbanization, sustainability, and community wellness. By repurposing unused urban land, the project provides residents with a space to engage in urban farming, cultivate vegetables and herbs, and foster community connections. The design focuses on improving both physical and mental health through the therapeutic benefits of gardening and nature. At the same time, it promotes environmental sustainability by using organic practices, increasing green spaces, and contributing to the restoration of ecological balance. This innovative approach to urban living helps create a healthier, more connected, and sustainable urban environment.

In hydroponic lettuce cultivation, understanding and managing the photoperiod—the light and dark cycle—is essential for optimal growth. Lettuce, being a long-day plant, requires 12 to 16 hours of light each day for healthy development. The light needs vary across different growth stages, with seedlings requiring up to 16-18 hours of light and mature plants benefiting from 12-14 hours to prevent premature flowering (bolting). The use of full-spectrum LED grow lights is highly effective in providing the necessary blue and red light, which supports photosynthesis and improves leaf quality.

LED grow lights are a vital component in hydroponic systems for growing bok choy, as they offer precise control over the light spectrum, enabling faster growth and higher yields. By optimizing the balance between blue and red light, growers can enhance photosynthesis, improve nutrient uptake, and accelerate the growth of leafy vegetables like bok choy. The low heat output of LED lights also conserves water and reduces energy consumption, making them perfect for urban farming and vertical farming systems. 

Soilless cultivation—including hydroponics, aeroponics, and substrate cultivation—has revolutionized modern agriculture by enabling efficient and sustainable crop production without the need for traditional soil. These innovative methods provide numerous benefits, such as water and land conservation, higher yields, and better disease control, all while reducing the need for chemical fertilizers and pesticides. As a result, soilless cultivation is increasingly seen as a solution to many of the challenges faced by conventional farming.

Hydroponics is a method of growing plants without soil, using a nutrient-rich water solution to provide essential minerals for plant growth. This system offers several advantages, including water conservation, shorter growth cycles, higher yields, and a reduced risk of pests and diseases. Common hydroponic crops include lettuce, spinach, pak choi, and various herbs, which thrive in well-controlled environments. The growing medium typically consists of perlite, vermiculite, or rock wool, and the plants' nutrient solution must be carefully prepared and regularly changed to ensure optimal growth. 

Microgreens are the tender shoots of vegetables harvested after the cotyledons develop their first true leaves. They are nutrient-dense and offer enhanced flavor, texture, and visual appeal to dishes. Typically harvested within 10 to 25 days of sowing, microgreens are highly regarded for their high concentrations of vitamins and antioxidants. Their cultivation requires careful attention to light conditions and growth mediums, with artificial lighting often used in commercial settings. Microgreens are more nutritious than their mature counterparts, containing up to five times the amount of vitamins and carotenoids.

Urban hydroponic farming is revolutionizing agriculture in densely populated cities by offering a sustainable, efficient way to grow fresh produce. Through innovative methods like vertical farms, rooftop greenhouses, and community hydroponic gardens, this approach maximizes space, reduces environmental impact, and strengthens local food security. Leveraging materials like hydroponic sponges, aerogarden grow sponges, and organic sponges, urban hydroponic farming fosters sustainability, community engagement, and a greener future for urban areas.

Urban community farms harness the power of sustainable planting substrates like grow sponges for hydroponics, coco peat blocks, and organic sponges to transform underutilized city spaces into vibrant green hubs. These farms promote environmental sustainability, enhance community bonds, and improve residents' health and well-being. By incorporating modern tools and techniques, urban farming paves the way for greener, healthier cities and a more sustainable future.

With increasing awareness of environmental protection, schools are placing more emphasis on ecological education, helping students understand the importance of natural environments and sustainable development. For primary, secondary, and even higher education institutions, integrating modern technology with natural ecology not only enhances students' scientific literacy but also nurtures their creativity and practical skills. Today, we will show how a school successfully created a unique ecological education corner by using an innovative soil-free growing medium, the plant growth cotton "π Soil"， offering students an ideal platform to both learn and practice.

This article explores the growing trend and nutritional benefits of microgreens, young seedlings harvested shortly after germination. These small plants are grown in hydroponic systems using soilless planting methods like organic plugs or π soil sponges. Known for their rapid growth cycle (10-14 days) and high nutrient density, microgreens have become a popular choice for chefs and health-conscious consumers. The article details their historical development, optimal growing conditions, importance of LED grow lights, and potential for commercial production, highlighting their profitability and versatility in the kitchen.

This article explains how to grow microgreens in a Nursery Station to maximize space utilization and increase revenue. It introduces microgreens as small but nutrient-dense plants harvested early in their growth cycle. The guide covers the benefits of microgreens, including their rapid growth, high market demand, and premium pricing. It also provides a step-by-step approach to growing microgreens hydroponically using soil-free planting sponges, offering a sustainable and efficient farming method. With minimal investment, microgreens can provide significant financial returns for commercial or home growers.

Mold and algae growth on AeroGarden sponges is common in hydroponic systems, but it’s often a natural and manageable issue. While mold, particularly Trichoderma, can be beneficial to plant health by suppressing harmful pathogens and promoting root growth, algae can compete with plants for light and nutrients if left unchecked. To manage these issues, ensure proper moisture control, storage, and regular cleaning of the AeroGarden system. Using hydrogen peroxide for mold removal is safe, and blocking light to prevent algae growth is effective. Experimenting with alternative growing mediums, like coco coir or rockwool, can also support plant growth while reducing mold and algae concerns. Proper care and maintenance will help your AeroGarden thrive and keep your plants healthy.
