How Much Water Does an Aerogarden Hold?

Keeping the animals aside, you already know how much essential water is for even the plants that grow around us!

But, you may not know about the increase in the importance of water when these plants are grown using indoor processes like hydroponics.

Keeping the distinction of this water in mind, one such best hydroponic system of growing out your plants is an Aerogarden.

Here, the most significant thing for the plants, known as the water supply, is maintained systematically and consistently.

You always need to start with a definite amount of this water for the very first time of your Aero-gardening. However, you may become confused about how much water you need and what amount they can hold while doing so!

The article is all about it, which can assure you of starting your Aerogarden with much better confidence!

How Much Water Can Your Aerogarden Hold?

Before directly entering into such answering, we need first to clarify the whole topic. With that being said, Aeroponics is one of the hydroponic system sectors used to grow your plants, breaking through their limits.

Here, the main center of attraction is the soilless system of cultivating your plants which doesn’t also involve other factors of the environment. Such as dependency on sunlight, waiting for the rain, taking help from birds and insects for pollination, etc.

Here, everything has an alternative and artificial solution, which is way more effective and available all the time. Plants grown under Aeroponics can seek out the maximum benefits of a hydroponic system, thus yielding higher and quicker.

Plants in this system are so much economical to grow than the traditional system, which involves soil. As a result, one can introduce any plant all over the year by this artificial method.

Although the system does not let your plants depend on the environment’s naturals factors, they need the proper alternatives.

One of the crucial tasks of this system that works by providing alternatives is the proper supply of water. Imbalances in this supply can make the whole project suffer.

So, growing plants in an aerogarden require frequent watering, which calls for a certain amount of water for individual project sizes.

Finally, we came to the question of how much water an Aerogarden can tolerate. Again, these number largely depends on the capacity of your model.

For a model of 3 pod units water needed is 0.3 gallons. A 6 pod unit will seek for 0.75 gallons. The nine pod model will hold 1.1 gallons, whereas a farm range holder can keep up to 2 gallons of water.

Select the ranges according to your scenario and needs and operate a perfect Aerogarden for your plants to grow.

What level of water should you keep for your Aerogarden?

The level of water in your Aerogarden always depends on a significant factor. And that is the nutrient supply of the system to the plants.

In an Aerogarden, the importance of nutrients is as much as the soil in a traditional system. Did you ever see any plants in a conventional design that grown without soil? It is like a boat without a rudder.

You can only see soilless plants in an artificial growing system like hydroponic who’s most prominent example is the Aerogarden.

Now coming towards the nutrients, it is mixed with the water and supplied to the plants in ample amounts. Without water, providing nutrients is almost impossible. Again, plants remain submerged within the water mixed with these nutrients.

So, even if you somehow manage to supply the nutrient to the plants through this system, you cannot have the plants take them without a water medium.

The absorption of this nutrient by the plants occurs through their roots system. Diffusion occurs at the roots and around the sources, where higher concentrations enter into lower concentrations regions. Here, areas surrounding the plants filled with nutrient solutions are at higher concentrations.

And, the lower concentration refers to the plants themselves. So, as a result, during this process of nutrient consumption, the water ends up first.

Plants constantly absorb the water much faster than the traces of other nutrients mixed with the water. So, when there remains no water, the nutrients stay below the grow trays as sediment, which the plants do not absorb.

As a result, a much higher level of water is required than the number of nutrients supplied. So, it is always suggested to top up the water level in your Aerogarden.

Also, don’t keep the nutrient-enriched water under direct sunlight. Otherwise, algae will occur within the water.

What is the type of water that you can use for your Aerogarden?

Water that suits the best for your plants should be the same through which they need to be cherished. This is because plants are so much sensitive to certain things like we humans do. Almost all living beings have this particular sensation and allergy.

One such thing that is so much irritating for the plants is the content of chemicals. Plants can even give off their food, water consumption, nutrients, and everything only to save themselves from those certain chemicals and components. In the same process, they can even end up their growth and development.

One of the other main things that plants cannot tolerate is the continuous supply of those elements that they don’t prefer. These things can be present in your water, surprisingly, which you have no idea of!

So, you have to be very picky with the water supply, especially in a system like Aerogarden. Because such method of growing out the plants mainly focuses on water and nutrient supply. Plants also grow in this system depending on that factor. If the water itself is not suitable, then how come you even expect to yield out of your plant from such systems?

So, besides the traditional cultivation method, you should prioritize the water quality in the Aeroponics system.

Some kinds of water that your plant doesn’t prefer in aero gardening are as follows:


Previously, everyone came with the conception that rainwater is the best water source for irrigation. But, the fact has some limitations, especially in an artificial cultivation system like Aeroponics.

You cannot even avail rainwater to the Aerogarden plants in the first place as this system is separated from the outer environment. So, rainwater can’t reach your plants.

But, in case if you collect the rainwater and use these for your Aerogarden, then the result will be unsatisfying.

Because rainwater is unpredictable in terms of mineral content, so you cannot take even a 1% risk. However, it can change the entire nutrient content of the system and cause your plants to suffer.

Well water

Again, well water can turn into the possibility of high mineral contents. You are already supplying your plants with enough minerals mixed with the water in your Aerogarden. A further of the minerals can turn out to be too much.

When anything done in excess can come to no good and may further add to be as harmful. To avoid the excess minerals, your plants may give up absorbing the nutrients at all. This will restrict their growth.

Soft water

Sometimes, if water is problematic in your area, you use a water softener to soften them. But this type of water is not eligible for your aero gardening despite being suitable for you.

Water softened by the water softener can turn out to be high in salt contents.  A higher level of sodium can also create unbalance in the total nutrients of your system.

Water below 50 ppm is regarded as soft water that contains a higher level of salt to make such water. This increase in salt can create restrictions for your plant’s roots to absorb those water in the first place.

It is undeniable as every plant is not salt-tolerant like the one from the coastal areas.

Hard water

Even high water in certain minerals like magnesium and calcium is not suitable for your plants. Hard water is such an example that can slow up the process of nutrient absorption for your Aeroponics plants.

Water that is above 120 ppm is known as hard water. Don’t ever use them, even if you have some water availability problem. The plants will survive longer without water than their survivability rate when supplied with hard water.


Spring waters are also high in contents of minerals. You can only supply this water to your plants until you can calculate and spot the mineral amount of such water.

By adjusting the amount with your nutrients supply to the plants, you can balance the content and make the water eligible. But this process is so much complex that we suggest you not go for this kind of water in the first place.

Dehumidifier water

Your house can have a dehumidifier system to purify the water coming from local sources. But, while performing such action by the dehumidifier, the mineral content in the water becomes so much unpredictable and unknown.

As a result, you cannot ever guess their mineral content unless you’re doing some water test. So, please don’t put your plants at any risk until you are sure about what you are ensuring to them.

Final Words
