The Best Hydroponic System Option


Hydroponics—the practice of growing plants in water rather than soil—is popular because it offers the user a way to produce a bounty of plants in a relatively small area in an indoor garden. Hydroponic growing provides several other benefits, including a reduced risk of soilborne plant diseases, so even newbie growers are more likely to succeed.

A wide range of consumer hydroponic systems are available for growing fresh produce indoors. Best of all, these systems often are all-inclusive: They provide the container for growing the plants as well as the tools and methodology for keeping plants healthy and robust. Ahead, learn which features are necessary for a hydroponic system, and find out why the following are well suited to indoor gardening.

The Best Hydroponic System Option


What to Consider When Choosing the Best Hydroponic System

Plants need four essential elements to thrive: water, oxygen, light, and nutrients. A successful hydroponic system must supply an adequate amount of all four. For those new to indoor hydroponics, the options may seem confusing, but today’s manufacturers create hydroponic units that automate much of the process.


While all hydroponic systems supply plant roots with water and nutrients, the method varies. All six of the common types of hydroponic systems have strong points, but some are better suited to commercial than DIY home settings.

  • Wicking: Also known as “passive hydroponics,” wicking uses an absorbent material, such as a natural fiber rope, to draw water from a reservoir to the plant’s roots. Wicking can be as simple as putting a plant in a soilless growing medium, such as perlite, and running a short piece of rope from the growing medium to water. This method is well suited for small plants or to teach children about how plants grow.
  • Deep water culture: Often found in all-inclusive consumer hydroponic systems, deep water culture (DWC) involves growing plants in small mesh pots where the plants’ roots spread through the water in a reservoir. A DWC system comes with up to 20 mesh pots, depending on size, and it features a small pump for circulating and adding oxygen to the water. DWC systems that are consumer-friendly also come with grow lights.
  • Ebb and flow: Also called a “flood-and-drain” system, the ebb-and-flow method involves flooding plant roots with nutrient-rich water and draining the water. By exposing the roots to water and nutrients every couple of hours, the plants receive all the nutrients they need, yet the roots don’t sit in water. Ebb-and-flow hydroponics is mainly reserved for commercial growing systems.
  • Nutrient film technique: Similar to a DWC system, a nutrient-film technique (NFT) system circulates nutrient-rich water through the roots of the plants. Rather than placing mesh pots in a water reservoir, the pots are side by side in long channels. An NFT system can contain many or only a few connected channels. While this system is used extensively for commercial growing, a few smaller NFT systems are available to consumers for in-home use.
  • Aeroponic: Rather than suspending plant roots in water, in an aeroponic system the roots sit above the water level, and a mister sprays the roots with nutrient-rich water. This type of hydroponics isn’t quite as popular as DWC for home systems, but a few models are available.
  • Drip: Usually limited to commercial growers, drip hydroponics feature tubing with small drip nozzles located above every plant. Water circulates through the tubing, drips on each plant, and the excess water runs through a mesh pot containing soilless medium and drains back to the pump. The dripping cycle repeats every few minutes.

Experience Level

To operate a commercial hydroponic growing system, the operator must have advanced experience in monitoring water flow, nutrient levels, and the pump. Even a little downtime can result in plant roots’ drying out and dying.

Fortunately, with today’s consumer hydroponic systems, indoor gardening is simple and straightforward. Systems like the popular AeroGarden come with mesh pots and soilless medium (often coconut coir plugs) as well as a pump or mister that’s preset to turn on and off at optimal intervals for circulating water and keeping roots moist and healthy. Most of today’s in-home systems also feature grow lights on timers that provide the correct amount of light.

Available Space

In hydroponics, users can grow more plants on a smaller footprint because the roots don’t need to spread out to seek nutrients. A typical home hydroponics system can be as large as a few feet deep and wide or as small as a few inches deep and wide, depending on the type of setup and the number of plants. The most common models can fit on a kitchen countertop or a table and take up no more than 1 to 2 square feet of space.

Plant Types

When growing plants indoors, opt for dwarf and small plant varieties. The most suitable types of plants for a home hydroponics system include herbs such as dill, chives, and basil; leafy greens; bush-type cherry tomatoes; and small peppers. Flowers also can be grown in hydroponic systems.


Consistent temperature is essential to plant growth, so commercial hydroponic growers often have water heaters to regulate the water temperature, usually between 65 and 75 degrees Fahrenheit. In-home hydroponic systems don’t require the same temperature control level because they’re usually placed in a home where the temperature remains between 60 and 80 degrees.

Substrates and Nutrients

A soilless growing medium is normally used in hydroponics. In-home systems often come with small coconut coir plugs that fit into mesh pots. The user puts a seed in a hole in the plug and inserts the plug into a mesh pot. The bottom of the plug sits in the water or is misted regularly with water, which triggers germination. As the plant grows, its roots extend below the mesh pot into the reservoir or channel beneath.

The nutrients in hydroponic systems are usually in liquid form, so they disperse quickly in the water. Some manufacturers provide a small bottle of this plant food with the initial system purchase, but users can order or purchase liquid nutrients in garden centers. Most liquid nutrients, which have a pH value between 5.8 and 6.3, contain the minerals necessary for robust plant development.


Today’s automated hydroponic systems require minimal maintenance, although the user should clean the unit thoroughly after each harvest before starting another crop. Plants grow quickly in hydroponic systems; in fact, they may reach the end of their useful lives in just 3 to 4 months. During the growing cycle, simply wipe down the unit’s surface with a clean, damp rag to maintain its appearance. If local tap water contains a lot of minerals, such as calcium and iron, consider filling the reservoir with filtered water to reduce mineral deposits in the tank.

Our Top Picks

To qualify as a top pick, a hydroponic system should feature a circulation system that keeps the water fresh. If it’s an all-inclusive system, it should come with a bright grow light that can be adjusted in height as the plants grow taller. The following hydroponic systems vary in design and size, but each is well suited to growing healthy herbs and plants indoors.

The Advantages of Owning a Hydroponic System

Without soil, plant roots can develop up to five times quicker by accessing nutrients directly in water. With an all-inclusive hydroponic system, growing herbs, fruits, veggies, or flowers indoors doesn’t have to take a lot of time or require a sunny window.

  • Hydroponics allows users to grow herbs and vegetables indoors year-round.
  • A quality system provides notifications that alert users when to add water and nutrients.
  • Hydroponic systems with grow lights don’t require a sunny window.


Because hydroponic systems automate the growing process, users don’t need a lot of hydroponic knowledge to enjoy fresh herbs and produce. For those new to growing indoors, some questions are to be expected.

Q: What is the best hydroponic system for beginners? 

For those just developing a green thumb, an affordable hydroponics system automates lighting and watering, offers several growing stations, and makes it simple to monitor water levels.

Q: How do you aerate hydroponics?

Inclusive systems come with built-in aeration via a pump, or they position the plants high enough above the water to expose the upper portion of the roots to air.

Q: Do I need to test the pH of my nutrient solution?

No. Nutrient solutions are pre formulated to offer the best pH level for a wide variety of plants and herbs. However, you may want to test the pH level of the water in the reservoir with a pH test kit and add pH adjusting liquid to raise or lower the pH level to between 5.5 and 6.3.

Q: How do I adjust the pH in my hydroponic system? 

To maintain a strict pH level, pH adjusting liquids are available, and a couple of drops of either “pH Up” or “pH Down” can change the level.

Q: Do I need to clean my hydroponic garden system?

After removing spent plants, thoroughly clean the unit before using it again. Apart from that, wipe it down with a clean, damp rag as necessary to remove dust or grime.
