What is Indoor Gardening Without Soil?

Indoor gardening without soil, also known as 'Hydroponics', is a technique of growing plants without soil.

It uses water mixed with nutrients to grow plants rather than soil. The roots of the plant are submerged in nutrient-rich solutions, which provide all necessary nutrients (such as minerals) for growth and sustenance.

This technique allows you to grow almost anything if you provide the right environment and conditions.

Plants grown in hydroponics often grow faster than those grown using the traditional dirt-based approach. And these plants are often more nutritious!

This is because, in hydroponics, the plants get better nutrients and oxygen, which is often lacking in soil.

It's especially beneficial for those who don't possess a large land patch and only have minimal space in their homes.

In this blog post, we will discuss how to do indoor gardening without soil and why it may be your next big thing!

Getting Started With Indoor Gardening Without Soil

  • To get started with growing plants without soil, you will need a container to hold the water and nutrient solution, also known as a hydroponic reservoir. For this, you can use any type of pot or bucket that is large enough for your plants.

  • The next step would be adding some sort of fertilizer (aka hydroponic nutrient) to the hydroponic reservoir and fill it with clean distilled water.

  • The final step is to adjust the pH of the mixture to ~5.5 to 6.5 using pH meter and place your plants into the container.

  • The roots of the plants will then be submerged in this nutrient-rich solution, which provides all necessary nutrients for growth.

  • You can use the hydroponic substrate to support your plants in hydroponics.

  • Finally, you should provide the environment such as temperature, relative humidity etc which is appropriate for the growth of your chosen crop.

Benefits of Indoor Gardening Without Soil

There are several benefits of indoor gardening without soil over soil-based gardens.

advantages of hydroponics-indoor gardening without soil
  • Faster growth: One major benefit is that plants grown with this technique grow much faster than those using the traditional dirt approach, which means you can get more produce in less time!
  • Higher nutritional content and taste better: These plants have a higher nutritional content and taste better (due to lack chemicals). So they are perfect for anyone who wants their family's diet improved without sacrificing flavor or nutrition value.
  • Can be simple and easy: Another great thing about growing your own vegetables indoors hydroponically is that you don't need any special equipment like greenhouses. It’s easy enough that anyone who is new to gardening can do it - just some containers filled up with hydroponic substrate such as coco-peat, stone wool, or perlite along with some hydroponic nutrient solution which constantly nourishes your plant as you watch them grow healthy and vigorously at you own home.
  • Less messy: If you're looking for a more convenient and non-messy way to grow your plants, then hydroponics may be the answer!
  • Growth all year round: You can have fresh vegetables all year round indoors without worrying about what season it currently is outside!
  • Saves space: Planting with soil requires more space. if you're a small-space dweller, you'll be happy to know that gardening indoors without soil is possible through hydroponics.

  • Saves water: Contrary to what you might think, hydroponics saves more water than the traditional way of gardening. Plants in hydroponics don't need watering once the system has been set up properly.
  • Better weed management: When you are using hydroponic gardening, you won't have to worry about weeding! You can focus on what's important: making sure that plants receive all of their nutrients and water.
  • Faster plant growth rates and higher yields per square foot than soil gardens, because plants are able to receive more nutrients in a shorter amount time.
  • A hydroponic system allows you to optimize the water and fertilizer based on your plant's need. Plants will need to consume a lot of water and fertilizer in order for them to stay alive and grow properly. This may, however, be lacking in most soil.
  • Hydroponics allows you to optimize nutrients precisely so that your harvests will be more consistent and plentiful.

You'll never miss out on that juicy tomato or crisp cucumber again as you can grow any vegetable, all year round!

How To Do Indoor Gardening Without Soil?

Hydroponics is made possible with a powerful substance referred to as a nutrient solution. This is basically water that has been enriched with minerals and other nutrients to help plants grow better than they would in soil.

In addition, the plants are provided with the perfect environment for optimal growth!

The roots of your plant will be submerged into the nutrient liquid which provides it everything necessary - no need of any dirt or sand type mediums.

This means you'll not only have less work but also have more produce per harvest.

Also, hydroponics is considered much healthier by many experts (due largely thanks to their chemical-free nature). And what's not to love about it?

What Are The Proper Methods For Doing Gardening Without Soil?

Now that you're aware of how hydroponics works, it's time to learn how to grow plants in water without soil. First things first! Grab yourself some supplies such as:

  • Reservoir - The first thing you need to start hydroponic garden is a container. The size of this will depend largely upon how many plants are in question and what type they may be (vegetables, herbs etc). You can use simple pots from home improvement stores that have drainage holes; alternatively there is also plenty available online if needed!
  • Net pots- The net pots for hydroponics are made of high quality, durable materials and are available in a variety of colors and sizes. These net pots can be used for growing plants in the green house, hydroponic, aquaponic and much more.
  • Growing medium- also called as substrate or grow media, provides a foundation to provide support to the growing plants. Rockwool, clay aggregate, coco chips, perlite, coco coir, peat moss, lava rock, vermiculite, river rock etc are just some of the materials that can be used as growing medium in hydroponics.
  • Seeds and Cuttings- Hydroponics allows you to grow almost anything provided you give an environment that is optimal for their growth which includes right temperature, humidity, light etc.
  • Grow Light- The light requirement for hydroponic depends on which crops you chose and which hydroponic system you choose.
  • Cleaning - An important aspect of growing vegetables indoors hydroponically is keeping a clean environment. While most gardeners do not need to worry about sterilizing their environment, those growing in hydroponic systems need a good sanitizing solution to effectively kill any bacteria or pathogens that may be present. The most common method for sterilization is using chemicals such as soap and warm water, bleach, hydrogen peroxide, or vinegar.

After you monitor and adjust these key variables, you can begin to discover precisely what your plants need in order for them to thrive. This will allow you to replicate those conditions for every growth in the future. Read more about how to maintain a hydroponic system?

What pH Is Best For Hydroponics?

pH is an important factor to consider in hydroponics since most plants are sensitive to pH changes in nutrients. Although the pH requirement depends on plants, most plants prefer pH to be around 6-6.5.

What Is The Best Indoor Hydroponic System?

There are several ways to do hydroponics. This method of indoor gardening without soil depends on the space available, and the kind of plants you want to grow. Some of the best indoor hydroponic systems are:

Some of these systems are easy to use for beginners. Others require more time but can produce a higher yield per square foot than traditional gardening methods.

Kratky method

Kratky method of hydroponic is perfect if you're spending a small amount of money or are just getting into hydroponics.

All you need is a pot, some rocks, a soil substitute, and your plant of choice. It’s that simple!

Fill your container with nutrient solution and water till the solution reaches ~3 inches from the top of the container.

Next, put your seedling in the net pot and ensures that the growing roots are constantly in touch with the nutrient solution and that it never dries out.

Ebb and Flow

Ebb and Flow also known as Flood and Drain method, is one of the most well-known hydroponics systems out there.

Ebb and Flow have a medium difficulty level for setup because it's versatile but not too expensive to build.

The basic concept behind Ebb and Flow is that plants are placed in grow trays with holes below them so nutrient water can be pumped into the plant's roots from a reservoir.

Water returns back into the reservoir from these grow trays once you open the drain.

Nutrient Film Technique (NFT)

Nutrient Film Technique, or NFT for short is a popular and dynamic hydroponics system.

NFT has a medium difficulty level and the system needs more space than Ebb & Flow.

In NFT, plants are grown in the channels (such as PVC pipes) and water is pumped into these channels from the reservoir constantly.

There's one unique difference between NFT and Ebb and Flow: In NFT, the roots are constantly being moistened by an ever-flowing 'nutrient film' unlike in Ebb and Flow, in which the nutrient solution is pumped periodically. Read more about how to build your own nutrient film technique at home?


Aeroponics is a revolutionary new technique for cultivating plants.

Plants roots are suspended in the air and nourished with nutrient-laden mist.

The roots are provided with periodic puffs of mists from specially designed misters, giving nutrients to the roots.

What Are The Plants That Grow In Water Without Soil?

You can grow any kind of plant in hydroponics provided you give the right nutrient, space, and appropriate environment such as light, temperature, and pH.

Some of the most common plants to grow in hydroponics include lettuce, basil, cucumbers, tomatoes, peppers. You can even grow citrus and apple and other trees if you are willing and are dedicated!

How To Manage Pests In Hydroponics?

Now that you know how to grow plants without soil, you need to know what are common pests in hydroponics.

Gardening without soil means that pests can't hide in the soil which significantly reduces their chances of survival and also they're more easily spotted by you.

Learn more about how to manage pests in hydroponics.


Why do people like hydroponic gardening?

People like hydroponic gardening because it is convenient and easy to maintain, it will save time by not having to do weeding, fertilizing, or other labor-intensive gardening activities, since most parameters in hydroponic can be timed and automated. With hydroponics, we can grow crops year-round since environmental parameters can be adjusted according to plants' needs. We can grow a variety of crops in the same space, year-round!

How much electricity is required for hydroponic systems?

The electricity requirement for hydroponic depend on the size of the system but in general, it can be from 25-320 watts per square meter

What are nutrient solutions?

A nutrient solution is a solution that contains all the necessary mineral nutrients for plant growth. It usually also includes additional ingredients such as fertilizer, vitamins, and micronutrients or supplements to provide essential sustenance to plants.

Can you grow hydroponics without nutrients?

The nutrient is important for the growth of any plant. Without it, the plants can't survive. So you cannot grow hydroponics without nutrients.

How good is hydroponics for a start in apartments and at home?

Hydroponics is great for people who live in apartments or at home, especially since it does not take a lot of space and does not require constant caring and management efforts as needed in traditional gardening.

What is the difference between aeroponics and hydroponics

Aeroponics and hydroponics are two different methods for growing plants without soil.
-Hydroponics is a technique of growing plants without soil. It relies on liquid nutrients which flow through the plants' roots.
-Aeroponics is also a technique of growing plants without soil and it relies on nutrient mist sprayed onto hanging roots in an open-air environment (not submerged into water).
