Water is an essential resource for all plants, but hydroponic systems especially rely on a regular schedule of watering to ensure their fruits and vegetables grow properly.

Eggplant is one such water-intensive crop that requires consistent moisture levels to develop quality fruit. The best way to achieve this is to monitor the soil’s water levels daily and adjust the frequency of watering as needed.

In general, eggplants should be watered every two days during the growing season. This means that if temperatures are high and dry, it is necessary to water them more often — perhaps even daily — in order to make sure they have enough water for proper growth.


Hydroponics is an increasingly popular method of growing plants without the use of soil. In this process, nutrients vital to the growth and development of plants are dissolved in water and delivered directly to the plant's roots through careful means.

This method of farming requires less land area and has been known to yield larger harvests than traditional agricultural methods. The absence of soil in hydroponics also permits for greater control over the plant environment - including temperature, moisture, light exposure, and fertilizer delivery.


Timers can be an invaluable tool when it comes to harvesting eggplant hydroponically. The perfect timing is essential to getting the best flavor and texture, so a timer can help you make sure that your eggplant crops are being picked at just the right moment.

When early harvest can lead to under-ripe fruit with less flavor, while waiting too long can result in over-matured produce that lacks complexity, using a timer allows you to get your crop at the peak of deliciousness.

How To Grow Eggplant Hydroponically - Step By Step

If you're eager to cultivate eggplant in your hydroponic garden, don't wait! Utilize this comprehensive guide to ensure success. The first step is to select the appropriate hydroponic system, as it is a crucial factor that can determine the outcome of your efforts.

What Type Of System Is Best For Growing Eggplant Hydroponically?

When it comes to growing hydroponic eggplant, the most important thing to consider is that these plants require a lot of oxygenation. That’s why two of the best types of systems for hydroponic eggplants are ebb and flow and DWC.

Ebb and flow is a simple system where the root zones of your plants are flooded with nutrient-rich water, then drained back into a reservoir. In this type of system, you’ll need an air stone and air pump in order to ensure adequate oxygen levels for your plants.

On the other hand, DWC stands for “Deep Water Culture” and it’s another popular system for growing hydroponic eggplant. The roots of these plants will stay submerged in nutrient-rich water, but with this method you will have multiple outlets that supply oxygen directly to the roots with an airs tone or injector stone.

This type of system is more complex than ebb and flow, but it can provide better access to optimal oxygen levels while still supplying nutrients with regular flood cycles. Ultimately, both systems have their own pros and cons so it pays to do your research before choosing one that works best for you.

Hydroponic Eggplant Propagation - Seeds vs Clones

Growing eggplants hydroponically is a great way to get a head start on the growing season. Planting seeds is the easiest and most common way to get started with hydroponic eggplant propagation.

In order to get the best results, keep the temperature around 70-90 degrees and make sure that your chosen variety of eggplant receives enough moisture.

After the seeds have sprouted and grown for two weeks, fertilize them with a soluble fertilizer and keep doing so until they are ready to be transplanted into your hydroponic setup.

It usually takes about six to eight weeks after sowing for this process to be completed for an average variety of eggplant such as Black Beauty.

When growing eggplants hydroponically, you don't necessarily have to start with seeds. Clones are also another good option when it comes to propagating eggplants in a hydroponic system.

Cloning allows you to take cuttings from already established plants and grow those in a controlled environment, rather than relying on natural processes like traditional seed planting requires.

This approach can save you time as you won’t need to wait as long for your clone plants to grow compared with starting from seed.

Feeding Your Hydroponic Eggplant Nutrients

Feeding your hydroponic eggplant the right nutrients is essential for growing healthy plants. The ideal pH should be around 5.5 to 6, with a ppm between 1750-2400. The nutrient solution needs to be monitored regularly and topped off with water when necessary.

Generally, these plants are relatively light feeders and only need their nutrient solution changed out once every 30-60 days, depending on the type of eggplant seeds you’re growing as well as its size and the type of hydroponic system you have.

It’s important to research what substances are necessary for optimal plant health and adjust for various factors such as temperature fluctuations and different types of eggplant varieties before establishing your nutrient regimen.

Caring For Your Hydroponic Eggplant

Caring for hydroponic eggplant is a little different than other plants, so it's important to do some research before you get started. Temperature should be kept steady and warm - the seed stage ideally needs temperatures between 70-90 degrees, with the vegetative and flowering stages being around 75-85 degrees.

Make sure not to let the warm temperature drop below 65 degrees or exceed 95 degrees as this can decrease your chances of setting fruit. Plants will also need supplemental grow lights - 8-10 hours a day is ideal – and LED are one of the best options available.

Additionally, they require higher humidity at around 50-65%, so if you don't have naturally humid air, consider investing in a humidifier or spraying your plants with a spray bottle occasionally. With some extra care and attention, your hydroponic eggplant will thrive!

How To Harvest your Hydroponic Eggplant

Harvesting eggplants from a hydroponic system can be a rewarding experience, as you can enjoy the fruits of your labor in no time. Eggplant seedlings typically require around 70 days to be ready for harvest and should be well-developed at this point. If they are smaller in size than when planting, then it may still need some more time.

When harvesting, make sure that you use a sharp knife or a pair of pruners to cut the short piece of stem attached to the top of each fruit. This should help avoid any damage to the plant and insure that future harvests will follow suit.

The beauty of harvesting with hydroponics is that multiple harvests can occur in succession and with the proper care, larger yields can be achieved.

To encourage continued production, regular pruning and nutrient delivery are crucial components for success.

Additionally, being mindful of environmental factors such as temperature and light play an important role in how successful your yields will be throughout the season.

Taking all these aspects into account will allow you to confidently harvest healthy eggplant from your hydroponic system in no time!
