Strawberry cultivation in hydroponics: systems, yield and keys to optimizing production

At Hydroponic Systems, we’ve been working for years with growers looking to improve the yield of their strawberry crops in controlled environments. And one thing keeps coming up: many systems aren’t reaching their full potential.

If you work with strawberries, you’ve probably already seen it. Irregular production, root problems, soil limitations, or a lack of stability between seasons. It’s not always a problem with the crop itself, but rather with the level of control you have over it.

This is where hydroponic strawberry cultivation completely changes the approach. It’s not just about replacing soil with another system, but about working with a model that allows you to control critical variables like water, nutrients, and root oxygenation much more precisely.

Throughout this article, you’ll learn:

  • Which systems are currently in use.
  • What yield you can expect under real-world conditions.
  • What factors make the difference between a system that works and one that’s truly optimized.

If you’ve been working with strawberries in soil for a while, you’re probably already familiar with its limitations.

One of the most common limitations is variability. Even with careful management, some factors are beyond your control: climate change, soil heterogeneity, and differences in water and nutrient retention. This results in plants that don’t behave uniformly, irregular yields, and difficulty maintaining consistent quality standards.

Added to this are soil-related health problems. Pathogens, soil fatigue, and the need for crop rotations directly affect crop stability.

But there’s another factor that often goes unnoticed: the feeling that you could be producing more.

Because, even if the crop is performing well, you know there’s room for improvement that you’re not fully realizing.

When you can’t precisely control water, nutrients, or the root environment, you’re limited. And that limitation is what ultimately determines both the yield and the final quality of the produce.

When you start analyzing more technologically advanced systems, something becomes clear quite quickly: the difference isn’t just in the growing method, but in the level of control you can achieve.

This is where hydroponics marks a turning point.

Unlike soil-based cultivation, working with hydroponic systems allows you to directly control the root environment. This includes water, nutrients, oxygenation, and even the temperature of the nutrient solution. In practice, this means you can adjust the system based on what the plants need at any given time, not the other way around.

And this control has a direct impact.

Variability

On the one hand, it allows for reduced variability. When conditions are stable, the plant’s behavior is also stable. This translates into more uniform and predictable yields, which is key if you work with demanding markets.

Continuous production

Because it is not dependent on the soil or traditional seasonal limitations, you can plan longer campaigns or even produce year-round under controlled conditions.

Water use efficiency

In well-designed and managed systems, consumption can be significantly reduced compared to traditional farming. In many cases, savings can reach up to 80%, mainly thanks to recirculation and precise irrigation control.

But beyond these factors, there is one that is usually decisive: performance.

Production per m2

When starting out with hydroponics, one of the first things that raises questions is this: there isn’t a single right system. And this is where many growers get stuck.

Under well-controlled conditions, hydroponics allows for increased production per square meter, improved fruit quality, and reduced losses associated with soil problems.

At first glance, it might seem like a technical detail, but it’s not. The system you choose directly affects crop stability, irrigation management, and ultimately, the yield you can achieve.

Therefore, rather than looking for “the best system,” the important thing is to understand what each one offers and under what conditions it makes sense to use it.

NFT system: when it makes sense and its limitations

The Nutrient Film Technique (NFT) system has been a benchmark in hydroponics for years. Its operation is simple: a thin film of nutrient solution circulates constantly around the root system.

It can work well in short-cycle crops or those with lower root requirements. However, it presents certain limitations in strawberry cultivation, which are frequently encountered in the field.

The problem is that it is highly dependent on the stability of the flow and oxygenation. Any interruption or variation can quickly affect the roots. Furthermore, the strawberry’s root volume and its sensitivity to oxygen deprivation mean that it is not always the most robust option.

Substrate cultivation: stability and management

Growing in substrates, especially with coconut fiber, is one of the most widely used options in professional production.

Its main advantage is stability. The substrate acts as a buffer, retaining water and nutrients and allowing for greater flexibility in irrigation management. This facilitates control in situations where conditions are not entirely constant.

Furthermore, it allows for more flexible setups and adaptation to different greenhouse conditions.

In practice, this translates into more tolerant systems, but also less precise ones if drainage and salt accumulation are not managed correctly.

Systems in elevated gutters: aeration, drainage and efficiency

Elevated gutter systems are designed to optimize the root environment. They allow for more efficient drainage, improved aeration, and much more precise irrigation control.

Unlike other systems, they significantly reduce the risk of waterlogging and problems associated with oxygen deficiency at the root zone. In real-world production, this translates into more stable crops with fewer disease problems.

In many cases, when analyzing actual greenhouse configurations, it is observed that this type of design allows for higher planting densities and improved crop uniformity.

Which system to choose based on your type of production

At this point, the question isn’t just which growing system to choose, but how to manage drainage and the root zone when working with substrate bags.

In professional tomato, pepper, cucumber, strawberry, or other substrate-grown crops, the bag should not be in direct contact with the drainage. When excess water remains below the substrate or accumulates without proper drainage, the risks of excessive moisture, lack of oxygen, and root problems increase.

Therefore, choosing a drainage collection gutter system with a spacer can make a significant difference. The gutter allows for the orderly collection and channeling of leachate, while the spacer elevates the bag, separates the roots from the drainage, and promotes better aeration.

If the goal is to improve crop stability, reduce health risks, and work with a cleaner and more controlled system, the choice of gutter should not be seen as merely a support. It is a technical decision that directly influences daily management, root health, and the final yield of the crop.

Before we talk about yield, there’s a key difference you need to understand.

In hydroponics, results depend less on the system you use and more on how you manage the variables that directly affect the crop.

And it’s precisely in this control that the true production potential is defined.

Nutrient solution temperature and root oxygen

Before making decisions about crop management, it’s important to consult with a head grower, crop manager, or experienced farmer. Each farm operates under different conditions: climate, water quality, substrate type, irrigation strategy, variety, planting density, ventilation, drainage, and level of technology. Therefore, what we explain here should be understood within a general technical framework, which must then be adjusted to the specific conditions of each project.

The temperature of the nutrient solution directly affects the amount of oxygen available to the roots. This has an immediate impact on crop development.

As a reference, working around 20°C is usually the optimal point in most well-managed systems.

Above this range, dissolved oxygen decreases.

Below this range, nutrient absorption slows down.

In practice, this means that poor temperature management can cause root stress without it being immediately apparent. And when it is detected, the problem is often already advanced.

This is where the most costly mistakes usually appear.

Electrical conductivity (EC) and nutritional balance

Electrical conductivity (EC) is one of the best-known parameters, but it’s not always interpreted correctly.

Working within the range of 1.4 to 1.8 dS/m is common in strawberry cultivation, but the value itself isn’t the important factor. What matters is the balance.

An improperly adjusted EC can lead to nutrient uptake blockages, affect vegetative development, or compromise fruit quality.

This explains why some crops don’t reach their full potential, even when the system appears to be functioning correctly.

Planting density: impact on production per m²

In well-designed systems, it’s possible to work with between 105,000 and 125,000 plants per hectare, compared to the lower densities typical in soil.

This opens the door to increased production per unit area, but also introduces new challenges.

Higher density requires greater control over irrigation, ventilation, and system balance. If not managed properly, it can lead to competition between plants and affect crop uniformity.

This is where hydroponics allows for more precise adjustments.

But it’s also where poor management can limit yield.

Relationship between variables: why the system alone is not enough

Temperature, oxygen, nutrition, density… these factors don’t operate in isolation. They are completely interconnected.

For example, high temperatures reduce available oxygen.

Less oxygen affects nutrient uptake.

And that directly impacts crop development.

This is the critical point. The system is just the foundation. Actual performance is defined by its control.

And when this control is precise, the crop becomes much more predictable, stable, and amenable to optimization.

After understanding the systems and, above all, the variables that govern them, the question is inevitable: What can you really expect in production?

The short answer is that it depends. But the technical answer is much more interesting.

Production per m² in hydroponic systems

Under well-controlled conditions, hydroponic systems allow for higher planting densities and greater resource efficiency.

This translates into significantly higher yields per square meter compared to soil-based cultivation.

Increased yields are not uncommon when:

  • Planting density is optimized.
  • Nutrition is precisely controlled.
  • The root zone is kept stable.

Real-world comparison versus soil cultivation

Unlike traditional farming, where variability is difficult to avoid, hydroponics allows for much more predictable working conditions.

While soil-based farming is influenced by factors that are not always controllable, in hydroponics the system responds directly to how it is managed.

This has two clear implications:

  • Less variability between plants.
  • Greater production stability.

In practice, this impacts how much you produce and how you produce it.

Fruit quality: firmness, uniformity, Brix

Yield isn’t just about volume.

When the system is properly adjusted, fruit quality also improves:

  • Greater firmness.
  • Better uniformity.
  • More stable sugar (Brix) levels.

This occurs because the plant isn’t subjected to constant stress and can develop under more balanced conditions.

Why better-designed systems reduce losses and increase efficiency

Designs that prioritize drainage control, aeration, and irrigation stability have a clear advantage: they reduce the margin of failure.

Under real-world growing conditions, this translates to:

  • Fewer root problems.
  • Lower disease incidence.
  • Greater stability in crop development.

In fact, when analyzing results under real-world growing conditions, it becomes clear that the difference lies not only in the system itself, but also in how it is designed and managed.

What type of configuration makes the most sense in professional greenhouses today?

The systems that work best in professional settings are those that allow for:

  • Precise irrigation control.
  • Maintaining good root oxygenation.
  • Preventing water or salt accumulation.
  • Adapting to higher planting densities.

This is where configurations that prioritize root environment control stand out from other, more limited options.

And this isn’t just a theoretical matter.

When you observe real-world configurations in commercial greenhouses, it becomes clear which systems allow for greater stability and efficiency on a daily basis.

At this point, you probably already understand one thing: performance depends not only on the system you use, but also on the level of control you have over it.

And that’s where the difference lies between a crop that simply works and one that is truly optimized.

If you’ve identified limitations in your current system, now is the time to analyze them in more detail. In many cases, small adjustments to the design or management can have a much greater impact than it initially appears.

It’s also important to understand that there’s no single right solution. Every farm has its own unique conditions, and what makes the difference is how the system adapts to those specific needs.

Therefore, beyond simply implementing one-off changes, it makes sense to adopt a more holistic view of the crop. Evaluate how the variables interact, identify critical points, and address them in a structured way.

At Hydroponic Systems, we work precisely along these lines: helping growers transform their crops into a more controlled, stable, and efficient system, based on real data and field experience.

If you want to delve deeper into how to optimize your production or understand what type of configuration makes the most sense in your case, the next step is to continue exploring solutions and approaches that allow you to make decisions with greater technical expertise.
