New to hydroponics? This section is for you. We cover the basics, from understanding what hydroponics is to a simple, step-by-step guide for your very first home setup. Learn how to start small, with minimal space and cost, and discover which crops are best for new growers.
Absolutely. You don’t need a degree in botany or a lifetime of gardening experience to succeed with hydroponics. In fact, many people find it simpler and more forgiving than traditional gardening. Beginner hydroponic kits are designed with simplicity in mind. They come with pre-measured nutrient solutions and straightforward instructions. As long as you can follow directions for light, water, and nutrient feeding, you can grow a thriving garden.
Hands down, the Kratky method is the simplest and most affordable way to get started. All you need is a container (like a mason jar or a plastic bin), a net pot to hold the plant, and a balanced nutrient solution. There’s no need for pumps, electricity, or timers. The plant’s roots simply grow down into the nutrient solution as the water level drops. It’s perfect for growing single plants like a head of lettuce or a basil plant, and it’s a fantastic way to learn the basics.
The electricity consumption can vary greatly depending on the size and type of your system. A small, basic setup with an air pump might use less power than a standard light bulb. However, larger setups with powerful LED grow lights and multiple pumps will naturally use more. The good news is that modern LED lights are incredibly energy-efficient, and many pumps are designed to be low-power. Many growers find that the energy costs are a small price to pay for fresh produce year-round.
You will need a dedicated grow light unless your setup is placed in a spot with extremely strong, direct natural sunlight (like a south-facing window). For most indoor growing, a grow light is essential. Plants need specific light spectrums to perform photosynthesis, and regular household lights won’t cut it. LED grow lights are the most popular choice because they are energy-efficient, long-lasting, and provide the perfect light spectrum for plant growth. Using a grow light also means you can garden 365 days a year, regardless of the weather outside.
Yes, it’s one of the biggest benefits. Hydroponic systems can use up to 90% less water than traditional soil gardening. In a soil garden, a lot of water is lost to evaporation, runoff, or is simply not absorbed by the plants. In a closed hydroponic system, the nutrient solution is recirculated and reused. The only water lost is what the plants take up or what evaporates from the top of the reservoir, making it an incredibly efficient and sustainable growing method.
Dig a little deeper into the world of soilless growing. Here, we address common questions about the benefits of hydroponics versus soil gardening, the safety of hydroponic produce, and the potential for saving water. Get the answers you need to feel confident in your growing journey.
Many growers think so. Hydroponics allows precise control over water, nutrients, and pH. Plants usually grow faster, but it requires more monitoring and equipment compared to soil. However, it can use up to 90% less water than traditional gardening because the water is recycled within the system.
Yes, though it’s a bit tricky. You can use organic nutrient solutions, but they must be carefully balanced to avoid clogging the system. Certification also depends on local regulations.
Most people find they taste the same—or even fresher. Because nutrients and water are precisely controlled, plants often have consistent flavor and texture. Since they grow in a clean, controlled environment, there’s no risk of dirt or contaminants affecting their flavor.
Yes, absolutely. Hydroponic systems can use up to 90% less water than traditional soil gardening. In a closed hydroponic system, the nutrient solution is recirculated and reused. The only water lost is what the plants take up or what evaporates, making it an incredibly efficient and sustainable growing method.
Absolutely. In fact, hydroponics is the foundation for a significant portion of the modern agricultural industry. Urban farms and vertical farms are using large-scale hydroponic systems to grow everything from lettuce to strawberries in warehouses and rooftops. While it requires a significant investment in commercial-grade systems, lighting, and climate control, the demand for fresh, locally-grown produce is at an all-time high. It’s a field with incredible potential for those with an entrepreneurial spirit.
Every grower faces challenges. This section provides actionable advice for diagnosing and fixing common plant problems. Learn what causes yellow leaves, how often to change your nutrient solution, and the best ways to keep pests away. Think of this as your quick-reference guide for a healthy, thriving garden.
Yellowing leaves are one of the most common signs that something is off in your system. It could be one of several things. The most likely culprit is a nutrient deficiency, particularly a lack of nitrogen or iron. It could also be a problem with your pH level. If the pH is too high or too low, the plant can’t absorb the nutrients, even if they’re present in the water. Another possibility is simply too much light or even root issues. The first thing you should do is test your pH and EC (nutrient concentration) levels and adjust them as needed.
While it is technically possible, it’s not something most home growers attempt. Root vegetables are a bit trickier to grow hydroponically because they need a supportive medium to grow in, and the roots themselves need space to expand. Most home hydroponic systems are designed for plants that produce leafy greens, herbs, or fruit above the surface of the growing medium. For beginners and even intermediate growers, it’s best to stick to crops like lettuce, tomatoes, or cucumbers for the best and most reliable results.
On average, you should plan to change your nutrient solution every one to two weeks. Over time, the nutrient balance in the water becomes skewed as plants absorb what they need. Changing the solution ensures your plants get a fresh, balanced supply of nutrients. It also helps prevent the buildup of algae or harmful bacteria that can thrive in a stagnant system. Consistent monitoring of your pH and EC levels can also help you decide when a change is necessary.
Hydroponic systems are generally much less prone to pests than soil gardens, but they aren’t completely immune. Since there’s no soil, you avoid many of the pests that live in dirt. However, airborne pests like fungus gnats, aphids, and spider mites can still find their way to your plants. The best defense is prevention. Ensure your grow space has good air circulation, and inspect your plants regularly for any signs of infestation. You can also use natural deterrents like neem oil or beneficial insects to keep pests at bay.

Not sure what gear you need? We break down the essential equipment for every type of grower. From the most affordable starter setups to the pros and cons of different grow lights, this section helps you make informed decisions about your investment, ensuring you get the right tools for your specific goals.
A yield calculator is a powerful tool for planning and managing your garden. It helps you estimate the potential harvest based on factors like the type of crop, the number of plants, and your available space. By using it, you can set realistic goals, optimize your setup to maximize output, and even project how much a harvest might be worth. It’s a smart way to think like a seasoned farmer, not just a casual gardener.
A buyer’s guide is a comprehensive educational resource designed to help you understand a product category before you buy. It explains the features, terms, and key considerations—for example, what to look for in a nutrient solution. A review, on the other hand, is an evaluation of a specific product. A buyer’s guide tells you how to choose, while a review tells you what to choose.
Downloadables are a great source of detailed, actionable information that you can save and access anywhere. You can find things like printable feeding charts for specific plants, in-depth troubleshooting guides for common problems, or even blank garden planning templates. They’re fantastic for when you want to take expert advice with you to your garden, especially if you don’t have a reliable internet connection.
Efficiency tools are all about streamlining your gardening tasks. This can be anything from a calculator that tells you exactly how much fertilizer to mix to a simple checklist that helps you track your weekly watering and nutrient schedule. By reducing guesswork and manual tracking, these tools help you avoid costly mistakes like over-fertilizing or forgetting to water, which saves you money on wasted supplies and leads to a healthier garden.
Tracking your plant’s health is the best way to catch problems before they become catastrophic. Tools like a pH meter, an EC meter, and a light meter give you objective data on your growing environment. By regularly logging these metrics, you can spot trends and identify when something is wrong before your plants show signs of distress. For example, you can see your pH slowly creeping up and adjust it, preventing nutrient lockout before it ever affects your plants.
