Growing cucumbers with Hydroponics or aeroponics can either be a great choice for you, or a bad choice. You will need a lot of space and room to grow these! I’ll explain How to grow Cucumbers with Hydroponics and Aeroponics.

Let’s get to planting!

Hydroponic Cucumbers

Growing your own cucumbers can be a battle. I recommend you buy cucumber seeds that pollinate itself. When you start planting your seeds, plant it in a large container. The plant is going to grow and grow. If the container is too small, the plant will start to stress, turn yellow and you won’t have any cucumbers.

When planting your seeds, you’ll need about 2-6 feet apart from each. This is because the roots will start to become bigger and bigger and need lots of space to flutter out. If you need to pollinate your flowers yourself, this is a very time consuming process.

With cucumbers, there is a male flower and a female flower. The male flower is just a flower, while a female will have a super small cucumber under it. You will have to take the pollen from the male flower, using a paintbrush, and rub it onto the female flower. If you miss out on this step, the cucumbers will shrivel up and die. Keep this process up and you’ll have cucumbers in no time!

Aeroponic Cucumbers

Can you grow Cucumbers with Aeroponics? Yes, and I will tell you how. Growing with aeroponics is almost the same as hydroponics. The only difference is that this has a mist that constantly mists the plant’s roots. Follow along with the same steps as the hydroponic system, and you’ll have cucumbers soon!

Indoor Cucumbers

If this is your first time growing cucumbers inside, then this one’s for you. To achieve great, big cucumbers; you are going to need a lot of space. Like, 2-6 feet for each plant. The cucumber plant will grow pretty large. This plant is a huge water drinker, meaning you will have to keep up with the water and solution to keep it happy. If you notice the leaves looking stressed, check the water. When filling the system up with water, do not put too much. This will cause your root to drown. We recommend that you leave about an inch or two of the root dry to keep the plant happy.

Once your plants start to grow, you can use a plant rod to allow the plant to wrap itself around it. Yes, you can train a plant. You can even use yarn to hang from the ceiling, and clip it to the plant so it doesn’t start to dip over the side of the container.


Pruning is very important if you are trying to grow cucumbers indoors. If you notice that a few of your leaves are turning yellow or are starting to shrivel up. Then this may be a good time to start cutting a few of those off. When a leaf starts to die, the plant puts all of its energy onto that leaf to save it, which then takes away from the rest of the plant.

Pest Control

Just like any plant, pests are going to appear. For cucumbers, a few that are known to attack your plant are: white flies, spider mites, thrips , aphids, flies. You can control these by simply keeping your area nice and clean. Always clean up any spilled water around the area.


Diseases are common in any plant system. Growing cucumbers, you’ll have to keep out for Powdery Mildew, which is the most common. To avoid this, keep your area clean!
