Our recommendations

How we chose the best hydroponic garden tower

Hydroponics makes gardening more accessible to people with limited space and time, as well as those who don’t have a lot of experience. Our picks for the best hydroponic towers reflect that, with options that are easy to set up and provide most of what you need to get started. Some did require the purchase of extra accessories like LED lights, but we tried to focus on hydroponic towers that came with as many features as possible.

Because these towers are an investment, we looked for models that gave the opportunity for high yield, which could reduce the cost of groceries and provide you with fresh produce all year round. We also chose towers that met a wide range of gardening skill sets, as some people may look to hydroponics as a way to save money and provide their households with fresh produce, while others may view it as a fun hobby.

Who this hydroponic grow tower is for

Hydroponic towers give gardeners the ability to produce large yields of fruits, vegetables, and herbs without taking up a lot of space. These devices are perfect for small homes, apartments, and other living situations where outdoor space is limited or nonexistent.

They’re also low maintenance and highly versatile, making them a great option for novice gardeners or those who want to try their hand at indoor gardening without a lot of hassle. Hydroponic towers are also great for year-round gardening and for people who want to harvest high-yield crops without dealing with the messiness of traditional gardening.

Anyone interested in growing their own fruits, vegetables, and herbs indoors—regardless of skill level or space constraints—should consider investing in a hydroponic tower.

What to know before you buy a hydroponic growing tower

Hydroponic towers can make high-yield gardening possible regardless of your space restrictions. But not all models are created equal. Height, the number of plant holders, the types of plants it can accommodate, how easy it is to set up, and grow light compatibility are all important specifications to keep in mind before making your purchase. 

Types of hydroponic towers

The style of hydroponic tower you choose will ultimately come down to the amount of space you have, your personal preferences, and your goals for your indoor garden. There are a few different types to choose from, each with its own set of pros and cons. Familiarizing yourself with what’s currently on the market will help you make an informed decision. 

Hydroponic tower garden with lights

As a gardener, you know that light is a necessary element for plant growth. And while you could set up your hydroponic tower near a window, you might not get the optimal light exposure that your plants need to thrive. 

Hydroponic towers with built-in grow lights offer a convenient solution to getting the right amount of light to your plants. They’re ideal for beginner gardeners or those who don’t have a lot of natural light in their space, as they don’t require you to buy any additional LEDs. These models also allow you to garden year-round, regardless of the season. 

While they’re a great option for many, hydroponic towers with built-in grow lights can be more expensive than their non-lit counterparts. They also tend to be larger and heavier, which can be a downside if you have a small space.

Stackable planters

Likely the most basic type of hydroponic tower on the market, stackable planters are exactly what they sound like—a series of stacking pots that you can fill with fruits, flowers, veggies, and herbs to save water and space in your home.

Rather than watering each plant individually, water is poured into the top pot and then flows down to the others, hydrating each one as needed. These hydroponic towers are often made of durable and food-safe polypropylene and can be placed both indoors and outdoors.

Because they don’t require any special equipment, they’re a great option for those on a budget. But they’ll require more gardening know-how to ensure each plant gets the hydration and sunlight it needs.

Vertical hydroponic systems

If you’re interested in hydroponics but don’t want to deal with the hassle of setting up your own system, a pre-made hydroponic tower is a great option. These towers come with everything you need to get started, including grow lights, nutrient reservoirs, and irrigation lines. 

Most vertical hydroponic systems are large and can accommodate many plants.

While they’re the most expensive option on the market, they’re also the most turn-key and require the least amount of effort to set up. Just add water and plants, and you’re good to go.

While these systems may not be a good pick for those on a budget, they’re ideal for those who want a high-yield and little fuss.

What is needed for setup

The lure of hydroponic towers is that they make gardening an easier and less time-consuming chore. No more weeding or tilling the soil—all you need to do is add water and nutrients to the reservoir, and your plants will take care of the rest.

But before you can enjoy the fruits (or vegetables) of your labor, there’s a bit of assembly required. Nothing too complicated, but you will need to have a few items on hand to make your vertical garden an optimal growing space for your plants.

Here’s what you’ll need to gather to set up your hydroponic tower:

  • Light. If your hydroponic tower doesn’t come with built-in lighting, you’ll need to purchase LED grow lights separately. These can be placed on top of or next to your hydroponic tower, depending on the model.
  • Nutrients. No soil means no nutrients. To give your veggies, herbs, and fruits all the nourishment they need to grow, you’ll need to mix up a nutrient solution specific to the plants you’re growing and add it to the reservoir.
  • Grow medium. This is what your plants will be rooted in—and there are a variety of options to choose from, including coco coir, vermiculite, perlite, and more. Whatever you decide, make sure it has drainage and aeration.
  • Temperature. Most plants prefer a comfortable room temperature of 60-80 degrees Fahrenheit. Some hydroponic systems come with a built-in thermostat to help regulate the temperature. Still, you can also use a space heater or air conditioner to maintain the ideal growing environment.
  • Airflow. Proper ventilation is key to keeping your hydroponic tower operating at peak efficiency. You’ll need an oscillating or ceiling fan to help circulate the air and prevent your plants from getting too hot or humid.
  • PH adjusters. Because you’re likely growing a variety of plants in your hydroponic tower, you’ll need to monitor the pH levels of your nutrient solution and adjust as needed. Different plants need different pH levels, and this will ensure each plant is getting the right amount of acidity.

The advantages of owning a hydroponic plant tower

Ease and efficiency are the two main advantages of hydroponic towers, but in reality, these gardening devices offer a whole host of benefits for both novice and experienced gardeners alike.

Without the need for soil or finding the perfect place for natural lighting, vertical gardening opens up a world of possibilities when it comes to growing plants indoors. Year-round high-yields, even in small spaces, are a reality with these game-changing devices. And with technology always improving, the hydroponic towers of today are more user-friendly and efficient than ever before.

Here are a few more reasons to consider hydroponic towers for your indoor gardening needs:

  • They’re great for small homes or homes without any outdoor space.
  • They’re low maintenance.
  • They’re highly versatile and can be used to grow a wide variety of fruits, vegetables, and herbs.
  • They allow for year-round gardening.
  • They’re not as messy as traditional gardening.

Tips for using a hydroponic tower

Traditionally, gardening required a lot of knowledge and a hefty amount of experience before seeing any success. You had to know when to plant, how much water and sunlight each plant needed, and hope that the weather cooperated. But hydroponic towers have made it possible for anyone to enjoy the benefits of fresh, homegrown produce—regardless of their skill level.

Most hydroponic towers come with an in-depth instruction manual on how to use your specific model for optimal results. Following these guidelines is crucial for first-time users. However, there are a few general tips that all hydroponic tower gardeners should keep in mind:

  • Fill each planting pocket with about 4-5″ of growing medium before adding the plants in (unless otherwise stated in your user manual).
  • Choose a nutrient solution based on the type of plants you’re growing.
  • Keep the pH level of your plants between 5.5 and 6.5 (unless otherwise specified).


Hydroponic towers make it possible to grow a lush, bountiful harvest right in the comfort of your own home or apartment. But if you’re new to the world of hydroponics, you may have some questions. 

Here are a few answers to newbie gardeners’ most commonly asked questions about their hydroponic towers. 

What can you grow in a hydroponic tower?

One of the biggest advantages of hydroponic towers is their versatility when it comes to growing a variety of plants. Hydroponic towers can grow almost any plant, from herbs and leafy greens to flowers and fruits. However, plants with extensive roots or vines (like corn) may do better in soil. 

Here are some of the most common things that people grow in hydroponic towers:

  • Leafy greens – lettuce, spinach, kale, arugula, swiss chard, and other leafy greens are ideal for hydroponic towers because they have shallow roots and don’t require a lot of space.
  • Herbs – basil, parsley, cilantro, mint, and other herbs thrive in hydroponic towers because they’re fast-growing and can be harvested continuously.
  • Strawberries – these delicious fruits are easy to grow in hydroponic towers and can yield a high amount of fruit in a small space.
  • Tomatoes – while they require a bit more space, tomatoes can be grown in hydroponic towers and can yield a lot of fruit if properly cared for.
  • Peppers – bell peppers, jalapenos, and other peppers can also be grown in hydroponic towers and can yield a high amount of fruit in a small space.
  • Cucumbers – these crunchy veggies can be grown in hydroponic towers and can yield a lot of fruit if properly cared for.

These are just a few examples of what you can grow in a hydroponic tower – the possibilities are endless! The key is to choose plants that have shallow roots, grow quickly, and don’t require a lot of space.

What is needed to set up a hydroponic tower?

If you want to use a hydroponic tower, you’ll need the following:

  • Growing medium
  • Nutrient solution
  • pH adjusters
  • Oscillating fan
  • LED lighting
  • A consistent temperature of 60-80 degrees Fahrenheit

How much electricity do hydroponic plant towers use?

It depends on the model and what crops you choose to grow, but on average, hydroponic towers use anywhere from 120—270 watts of electricity.

How often should you change the nutrient solution in your hydroponic tower?

The nutrient solution in your hydroponic tower should be changed every 1-2 weeks, depending on the type of plants you are growing and the size of your reservoir. Think of it like giving your plants a refreshing spa treatment!

Changing the nutrient solution regularly helps ensure that your plants are getting the right amount of nutrients and keeps the water clean and fresh.

What pH range is best for different types of plants in a hydroponic tower?

Different types of plants have different preferences when it comes to pH levels, but a good rule of thumb is to keep the pH between 5.5 and 6.5. This range is ideal for most plants and helps ensure that your plants are absorbing the right nutrients at the right time.

Think of it as creating the perfect environment for your plant babies to thrive!

Can you use tap water for your hydroponic tower, or do you need to use filtered or distilled water?

While tap water can be used for hydroponic towers, it’s always a good idea to check the quality of your water first. Tap water can contain high levels of minerals, chlorine, and other chemicals that can harm your plants.

So, if you’re concerned about the quality of your water, it’s best to use filtered or distilled water. You want your plants to be drinking the cleanest water possible, just like you would want for yourself!

How do you prevent algae from growing in your hydroponic tower?

Nobody wants algae growing in their hydroponic tower – it’s like an uninvited houseguest that just won’t leave! One way to prevent algae growth is by keeping your tower out of direct sunlight, as algae thrives in bright light.

Another way is to use a cover or lid on your reservoir to reduce the amount of light that gets in. Lastly, you can add an algae inhibitor to your nutrient solution to keep the algae at bay. With a little preventative care, your hydroponic tower garden can be an algae-free zone!

What types of pests or diseases are common in hydroponic towers, and how do you prevent or treat them?

Just like any garden, hydroponic towers can attract their fair share of pests and diseases. While growing plants in hydroponics definitely reduce the pests that come poking around, it doesn’t eliminate them altogether. Common pests include spider mites, whiteflies, and aphids, while common diseases include powdery mildew and root rot.

To prevent pests and diseases, it’s important to keep your tower clean and well-maintained, and to avoid overcrowding your plants. If you do spot any pests or signs of disease, you can treat them with organic sprays or natural remedies, such as neem oil or a hydrogen peroxide solution. A little bit of TLC goes a long way in keeping your hydroponic tower healthy and happy!
