When it comes to indoor gardening, there are a lot of different ways to go about it. You can grow plants in soil, or you can use a hydroponic system. Hydroponics is a method of growing plants without soil. This type of gardening is becoming more and more popular because it is more space efficient than traditional methods. In this blog post, we will discuss how much space hydroponic plants need and why they are so space efficient!

What is hydroponic gardening?

Hydroponic gardening is a method of growing plants without the use of soil. Instead, plants are grown in a nutrient-rich solution or substrate, such as gravel or perlite. This type of gardening has several advantages over traditional methods, including increased space efficiency and the ability to grow plants all year long.

Why do we care about space efficiency?

There are a number of reasons why growing food in space efficient ways is important.

Urban Areas

Many people living in urban areas enjoy growing their own food. Small spaces can be difficult to cultivate traditionally, as they often don’t have enough light or room for growing mediums like soil.

In plenty of urban apartments, there is no balcony, porch, or yard. so Hydroponic systems are ideal to place indoors, so if you live in a small city apartment, it may be your best way to grow plants. If you don’t think your climate indoors is sufficient for urban gardening, you can get yourself a grow tent.

Not only does growing plants in an indoor hydroponic system mean that you can produce your own fresh produce all year long, but it is also ideal for those living in urban areas with limited access to fresh fruits and vegetables. Whether you are growing a small herb garden or a larger crop of tomatoes, hydroponics offers an effective and efficient way to produce your own food, regardless of the size of your space.

Food Safety

Another important factor to consider is food safety.

Hydroponic systems can help ensure the safety and quality of your product by providing a controllable growing environment, with strict temperature and humidity levels that are easier to maintain than in traditional soil-based gardens. This means less risk of contamination from pests or bacteria, and the ability to closely monitor the health of your plants.

Being able to grow food indoors in smaller areas assures that even with the population growth, people will still have access to fruits and vegetables and continue to get their essential nutrients.

Energy use

Another advantage of hydroponic gardening is that it is highly energy efficient. Since there is no need for soil, water usage and energy consumption are greatly reduced compared to traditional methods. It is also much easier to harvest them since they grow in a much smaller space. Growing the exact same amount of produce, hydroponic farms are smaller than traditional farms.

This can help minimize your environmental impact, as well as lower your costs over time.

Overall, hydroponic gardening offers a space-efficient way to produce your own food, regardless of where you live or how much space you have available. Whether you are growing just a few herbs for yourself or starting an indoor commercial hydroponic farm, there is an option that will work for your needs and space constraints.

Why is hydroponics more space-efficient?

One of the main reasons why hydroponics is more space-efficient than traditional gardening methods is that it uses less growing medium. Traditional soil gardens require a large amount of space for plant roots to grow, while hydroponic systems use much less substrate, allowing plants to take up more room in their system. In other words, by using a smaller growing medium that is only half as deep you can grow twice the amount of plants in the same space. Additionally, hydroponic systems often use vertical space more effectively, allowing you to grow more plants in a smaller area.

Another benefit of hydroponics is that it allows you to grow crops year-round, as the controlled environment is less affected by seasonal changes and fluctuations in temperature and light. This makes it possible to produce consistent yields regardless of weather conditions or outdoor growing conditions.

Hydroponic systems

The level of space efficiency depends on the growing method. There are different methods and systems for hydroponic growth, but all of them are space efficient. Some of them are:

Nutrient film technique (NFT)

-Nutrient film technique (NFT): In this method, plants are grown in channels or gutters that contain a thin stream of nutrient-rich solution. Because there is no soil to take up space, plants can be grown very close together in NFT systems. This makes them ideal for small-scale growing operations.

In this technique, the plant’s roots grow into a thin film of nutrient solution, which is constantly flowing through the channels. This makes it possible to grow crops more closely together with less substrate, providing more space-efficient growth.


-Aeroponics: In this system, plant roots are suspended in an air or mist environment and regularly sprayed with nutrient-rich water. This method is also ideal for growing crops with minimal space, as plants can be grown on vertical surfaces or within containers.

Drip system

-Drip system: In this approach, plants are placed in individual pots that contain a substrate and watered with a nutrient solution through a series of tubes. This allows you to control the amount of water that each plant receives and optimize the amount of space required for crops.

Here, the roots of the plants are suspended in the air, with nutrient-rich water being sprayed onto them. This is another space-efficient method of growth, especially for crops that thrive when grown vertically or within smaller containers.

Vertical Hydroponic Systems

But the main reason hydroponic gardening is so space efficient is because you can grow everything vertically!

One option is stacking plants or in vertical planters, allowing you to fit many more plants into a smaller space. And with the right lighting and climate control systems, you can grow your plants all year long, even during the winter months.

Another is growing them in layers, or levels. This is a great way to make use of the vertical space in your home, office, or greenhouse. Hydroponics can also be used to create hanging gardens or trellises that maximize the amount of space you have available for plants.

How much less space does hydroponics use?

Hydroponic plants require much less space than conventional plants grown in soil, due to several factors.

One key reason is that hydroponics allows farmers to grow more plants in a smaller area, as they can drastically reduce their land use while maintaining high levels of productivity. A Princeton study found that hydroponic systems are up to 90-99% more space efficient than conventional farming methods, making them a highly attractive option for farmers looking to maximize their crop yields.

Additionally, hydroponic systems can be easily moved and reconfigured as needed, allowing growers to optimize their growing conditions at all times.

Overall, the combination of reduced land use and increased flexibility makes hydroponics an extremely space-efficient growing method that more and more farmers are turning to.
