Building a vertical hydroponic garden can be an effective way to grow more plants in a smaller space.
There are many hydroponic systems to choose from, including deep water culture, nutrient film technique, and aeroponics.
When building a vertical hydroponic garden, factors to consider include lighting, growing medium, nutrient solution, water movement, and support structures.
To ensure the health of your plants, it’s important to monitor pH and nutrient levels, as well as factors like temperature and humidity.
With careful planning and attention to detail, anyone can successfully build and maintain a thriving vertical hydroponic garden.


Hydroponics is a method of growing plants in water, without soil. This differs from traditional gardening, where the roots of plants are planted in the ground and they grow their own nutrients from the soil. 

Hydroponics is used both indoors and outdoors, though it can take up more space than traditional gardening.

The benefits of hydroponic gardening include:

Efficiency: You don’t need to worry about your plants getting enough sunlight or making sure they have enough space to grow in their container. With hydroponics, everything is controlled by you!

Quality control: If there’s a problem with one plant, you can place it somewhere else until it recovers or throw away any bad buds immediately (without having to handle them).

No pests: Since pests don’t live in water like most insects do on land (with some exceptions), there will be no worries about harmful insects going after your prized crops!

Are you looking to grow your own hydroponic garden but don’t know where to start? Our beginner’s guide on how to build a hydroponic garden is the perfect resource for you. You’ll learn the basics of hydroponics, how to choose the right growing medium and hydroponic system, and tips for ensuring a successful harvest.

Things You’ll Need

Before you begin building your hydroponic garden, it’s important to understand the materials you’ll need. 

Depending on what size grow box you want to build and how large of a crop you’d like to grow, the list will vary slightly. Here are some things that we recommend investing in:

  • PVC pipes of varying sizes (we recommend 2′ lengths)
  • Nutrient solution or liquid fertilizer (available at most big-box stores)
  • Grow medium (we like perlite and vermiculite mixed together)

Locate Your Garden Near A Water Source.

Water is an essential ingredient in any hydroponic garden. The water must be clean, but not chlorinated or too clean. 

It should also be warm, but not hot. Water should be filtered, but not so much that it becomes mineral deficient. And the best place to put your water source is close to your plants—but not too close!

If you’re interested in building a hydroponic garden, consider a tower garden. Our step-by-step guide on building a hydroponic tower garden provides clear instructions and helpful tips for constructing a tower garden that will yield a variety of fruits, vegetables, and herbs in limited space.

Buy Some Pvc Pipes.

You can find these in your local hardware store, in a variety of sizes and lengths. You will need to buy some PVC pipes for your vertical hydroponic garden, and the size that you choose will depend on the type of plants that you want to grow.

You’ll also need a hacksaw or PVC pipe cutters if you want to cut them down any further than they come pre-cut in their packaging.

Mount The Top Unit To The Bottom One Using Pvc Cement Or Drill And Bolts

Mount the top unit to the bottom one using PVC cement or drill and bolts.

PVC cement is a super-strong glue that can be used on plastic and vinyl, so it’s perfect for this project. 

Make sure you read the instructions carefully before using it, as there are special procedures for mixing the glue and applying it properly.

Drill holes through both units at equal heights from where they will mount together, then use bolts (spaces between bolt holes should be equal) to connect them together

Test The System

You may be tempted to leave the system alone and let it run for a day or two, but that’s not always a good idea. 

You want to make sure there aren’t any leaks, that water is flowing through your system properly, and that it’s reaching all parts of the plant equally.

First, check for any leaks in the system. If you find one, take care of it immediately! Leaks are wasteful and can cause damage over time if they’re left untreated. Check each connection point carefully by running your fingers along them; if there is a leak somewhere, you’ll feel moisture on your hands after touching an area where water isn’t supposed to be coming out (but might).

Next up: make sure water flows through your entire vertical hydroponic gardening system without interruption before adding plants into the mix. 

Fill up one part at a time the base first (if applicable), then test each successive section until everything runs smoothly from top to bottom without any hiccups along the way. 

For example: if there’s no flow from top-to-bottom within a particular section (say with just leaves), then either remove some blocks so more room exists inside for water flow or add additional piping/tubing between sections so each level has access via its own channel downward towards roots! T

his ensures optimal distribution throughout plant parts instead of just surface growth only occurring because nutrients weren’t delivered properly due poor design choices made earlier on during construction process . . .

Make Sure The Plants Are Properly Aligned

When you’re ready to start building your vertical hydroponic garden, make sure the plants are properly aligned. 

Use a ruler or tape measure to make sure they are straight, and spacing should be even across the board. 

The plants should also be spaced according to their size: big plants like tomatoes need more space than small herbs such as parsley or cilantro.

Add Grow Medium

The next step is to add the grow medium. You can use any type of material that will retain water, but we recommend using Hydroton clay pebbles because they are lightweight and offer excellent drainage.

To add the grow medium to the top of your chamber, simply place it on top and press down until it’s level with all other parts of the chamber.

Now that you have added your grow medium, it’s time to get your plants into their new home!

Prepare A Nutrient Solution

Use a nutrient solution calculator. If you’re new to hydroponics, it can be helpful to use an online nutrient solution calculator or app like Hydroponic Nutrient Solution Calculator by This tool will help you determine the amount of nutrients needed and their concentrations based on the different plants in your system. It also factors in pH levels for each plant species!

Test pH levels before adding any nutrients. The pH level determines whether or not your plants are getting enough oxygen for proper growth; if it’s too high, the roots get burned from excess oxygen; too low means not enough air makes it down there! 

So make sure that pH is somewhere around 6-7 before adding anything else into the water supply—this should give them access

One of the most common challenges of hydroponic gardening is dealing with fungus. Our guide on how to avoid fungus in hydroponics provides a variety of proven tips and techniques for keeping your hydroponic garden healthy and free of fungus. From maintaining proper pH levels to using sterilized equipment, our guide covers everything you need to know.

Plug In Your Pump And Check For Leaks

Before you plug in your pump, make sure that it’s turned off. It’s important to check for leaks around the pipes and fittings at this point because once you start running water through your system, it could be too late for leaks. You may have to use a pipe plug or epoxy if there are any leaks.

Sure, here’s a table based on the semantic of the point “Plug In Your Pump And Check For Leaks”:

Checking for Leaks and Plugging Your Pump

1.Turn off the pump before plugging it in.
2.Check all pipes and fittings for leaks.
3.Tighten all fittings as needed.
4.Use caulk or plumber’s tape to seal any leaks.
5.Fill the hydroponic system with water.
6.Turn the pump back on and check again for leaks.
7.If you find any leaks, power off the pump and apply a pipe plug or epoxy to seal the leak.
8.Allow the epoxy to dry before turning the pump on again.
9.Once you have confirmed there are no leaks, you can start adding nutrients to the system.

This table outlines the steps to check for leaks and plug in your pump in a hydroponic system.

Add Plants After Germination

Your plants will need to be germinated first before you add them to your vertical hydroponic garden. 

Germination is a process where seeds sprout into seedlings and can be done in a few different ways, but it’s usually best to use a seed germination kit or do it yourself with another method like paper towels and water.

Once the seeds have sprouted, make sure that the soil around them stays moist. You can use an aquarium pump with an air stone attached to provide oxygen for your plants, which are sensitive when they’re young. 

Then place each plant at the top of their section so that they have plenty of room to grow up towards light.

Sure, here’s a table based on the semantic of the point “Add Plants After Germination” with a title in H3 format:

Adding Plants After Germination

1.After germination, carefully remove seedlings from the grow medium.
2.Wash the roots of the seedlings to remove any debris or dead roots.
3.Ensure that the pH and nutrient levels of the hydroponic system are optimal for the type of plant you are adding.
4.Gently place the seedling into the hydroponic system, ensuring that the roots are fully submerged in the nutrient solution.
5.Monitor the health of the plant and ensure that the nutrient solution and support structure are adequate for the plant’s growth.
6.Continue to monitor the pH and nutrient levels of the hydroponic system regularly.

This table outlines the steps for adding plants to a vertical hydroponic garden after germination.


If you follow these simple steps, you’ll be on your way to growing your own food in no time. This is just a basic tutorial for beginners, but there are many more ways to create an indoor garden that has everything from fish tanks to hydroponic systems and even aquaponics!
