Hydroponics, the practice of growing plants in water rather than soil, has gained popularity among hobby gardeners over the past 15 years. This method, which uses 90% less water than traditional agriculture, offers a sustainable alternative for water-conscious gardeners. Recent innovation in the field has further spurred interest.

Various hydroponic systems exist, ranging from simple to complex. Here are some easy ways to start your own hydroponic garden at home, whether you’re an expert or a beginner.

Key Elements of a Hydroponic Garden

All hydroponic systems share certain components. Plants need a growing medium to anchor their roots and retain moisture. Materials like rice hulls, clay pellets, and coconut fiber are commonly used. Net pots hold the plant and growing medium, typically floating above the water. The plant’s roots extend into the water below to collect nutrients.

Gardeners must add a nutrient solution to the water, tailored to each plant’s needs. These solutions vary in their ratio of key elements, such as potassium, nitrogen, and phosphorus. For example, herbs may require higher levels of potassium, while lettuce needs more nitrogen.

Starting a DIY hydroponic garden can be affordable, with basic supplies costing under $30.

Growing with the Kratky Method

The Kratky method is the simplest and cheapest hydroponic approach. Unlike other systems that use pumps, this method requires no electricity. Gardeners add enough nutrient solution at the start to last the entire growing cycle. Net pots are suspended above a container filled with water and nutrients. As plants consume water, the level decreases, and roots stretch further down, ensuring adequate oxygen exposure.

Named after researcher Bernard Kratky, this method is ideal for leafy vegetables like lettuce and herbs such as basil. Kits are available that include all necessary supplies, making it easy to set up.

Scaling Up Your Hydroponic System

To scale up, consider expanding your Kratky garden. “I’ve done a Kratky system with a 12-foot-long growing bed,” said Eric Weber from Plant Chicago. Deep-water culture is another scalable option, using air pumps to circulate oxygen. This method, starting at about $100, allows for larger-scale growing while remaining low maintenance.

Advanced systems can house vertical gardens up to six feet tall. They use tubes to circulate water and nutrients, with sensors to automate refills, costing several hundred dollars. These systems offer low maintenance and high yield.

Whether you opt for a simple or advanced setup, hydroponic gardening provides a low-maintenance, water-efficient way to grow plants at home.

COP29 Ends Amidst Criticism Over Loopholes and Disunity


The United Nations’ 29th Conference of the Parties (COP29) concluded with widespread criticism over perceived loopholes and a lack of unity among participating nations. Environmental experts and activists expressed concerns that the agreements reached may be insufficient to address the escalating climate crisis.



Despite initial optimism, the conference, held in Bonn, Germany, was marked by intense debates and disagreements. Key issues included carbon emission reduction targets and financial commitments to developing countries. Many attendees felt these discussions fell short of meaningful progress. Learn more about the UN’s climate change efforts here.



A significant point of contention was the establishment of clear guidelines for monitoring and reporting emissions. Critics argue that the absence of stringent measures allows countries to exploit loopholes, undermining global efforts to curb climate change. The lack of consensus on this issue highlights the challenges in achieving cohesive international action.



Some developing nations voiced frustration over inadequate financial support from wealthier countries, which they argue is essential for implementing sustainable practices and mitigating climate impacts. This financial gap remains a major obstacle, fueling discontent and hampering collaborative efforts. Explore the Green Climate Fund’s role in supporting climate action.



Meanwhile, environmental groups emphasized the need for immediate and robust action, warning that delays could have catastrophic implications. They called for greater transparency and accountability in future agreements, urging nations to prioritize the planet’s health over economic interests.



As COP29 ends, the international community faces the challenge of bridging divides and enhancing cooperation to effectively combat climate change. Stakeholders are now looking ahead to future conferences, hoping for more decisive action and unity.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.

Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
