Guide To Plant Hydroponic Strawberries Indoors

Guide To Plant Hydroponic Strawberries Indoors

Guide to plant hydroponic strawberries indoors. There is a seasonal gap in the production of strawberries. When it comes to high-quality strawberries in November, December, and January, stores and eateries frequently run out (or June, July, and August if you live Down Under).

Due to their need for daylight, there aren’t many strawberry cultivars that produce fruit in the final days of summer. Weather in the area is erratic and getting worse, and a late crop is destroyed by an early frost. Strawberries that are flown in from another continent are more expensive for consumers.

When it’s cold outside, strawberries grown in greenhouses have higher sugar, color, and flavor levels. This is especially true if they can be grown close to where they will be eaten, or at least on the same continent.

However, strawberry production in greenhouses not only satisfies consumer demand but also aids growers in maintaining their cash flow. Strawberry production is a logical way to boost profits and extend your season if you already have greenhouses.

However, there are some particularly significant considerations that aren’t obvious to most new growers that you should keep in mind before you take the plunge and dedicate a greenhouse you already have set up to strawberry production. They will be covered in this article.

Let’s begin by going over a very basic idea.

Field production is less dependable than indoor production.

You can adjust the light and temperature when growing plants indoors. Pests and diseases won’t be completely eliminated, but your efforts will be focused and constrained to produce better results with non-toxic methods. You can design your growing trays with ergonomics in mind to make harvesting less labor-intensive. Losses brought on by a freeze or a drought can be avoided.

While hydroponic production is typically more cost-effective, you are not required to use it to grow strawberries indoors if you are fully aware of the variations in nutrient requirements throughout the life cycle of your plant. You can give your plants the precise nutrients they require at the exact times that they require them. Just remember two fundamental principles.

The first guideline for producing strawberries profitably in a greenhouse hydroponic system is…

While most strawberry growers in greenhouses use buckets or a gutter system specifically made for strawberry production, strawberries don’t need their own containers. Strawberries can be grown in hanging baskets. If you already grow perennial plants in 3-liter pressed-fit pots, you can use the same system to grow really nice strawberries.

It’s not necessary to maintain the greenhouse at a tropical temperature. Berries prefer a cool environment. Strawberries can be stored overnight at 45° F/ 7° C. During the day, they prefer a temperature of about 75° F/ 23° C. The bare minimum of a home is adequate.

Better temperature regulation is always preferred. Controlling the temperature can always be improved. However, if you only have a little heat, there’s no reason not to try strawberries. Fruit quality is maintained while your plants are fruiting by having cool nights.

In fact, the quality of strawberries depends on some nighttime cooling. According to Mark Kroggel, a strawberry expert from the University of Arizona

Fruit quality will be significantly impacted if greenhouses cannot be cooled to 59°F or lower at night. The main issues will be an excessively high acidity, a low Brix (sugar content), and an irregular fruit surface. The strawberry begins to swell or turn mealy. The temperature has an impact on the texture, sweetness, and acidity.

Additionally, it’s critical to give strawberries the proper amount of light. To make sugar, strawberries need light. As a general rule, strawberries require a daily light integral (DLI) of 12 moles per square meter.

Daily light integrals, also known as DLIs, are like rain gauges, but for sunlight. Throughout the day, there are peaks and valleys in the brightness of the sun. Because of this, it is useless to measure the amount of light provided to plants using an overhead light measurement in lux, such as the lux produced by a sun lamp. Measurements of illumination for people using foot-candles are not useful for measuring light for strawberries.

DLI calculates the amount of chlorophyll (in moles) that is activated over the course of a 24-hour period by photosynthetically active radiation (sunlight with a wavelength between 400 and 700 nanometers, or roughly visible light, although not all visible light activates chlorophyll). If your plants receive the same amount of light throughout the day, every day, there are meters that can provide you with a 24-hour reading as well as an instant reading.

Your strawberries will get all the light they need on a sunny day, even in the dead of winter, if you live south or north of about 35° N latitude. On the other hand, light levels of 30 moles per square meter per day or more are excessive. Around the middle of March, your plants in the Southwest will start to receive too much light, and you will need to shade them. A good production requires the capacity to measure light and, as required, to add additional light or shade.

So, is it possible to grow strawberries in your greenhouse with the current lighting? Most growers who already have greenhouses will be able to provide light and temperature control, or at least light and temperature measurement that allows them to make up for limitations in their existing structures, for good strawberry production. It’s likely that you won’t need to make significant changes to start growing this new cash crop. But there are other things to think about.

The second guideline for producing strawberries profitably in a hydroponic greenhouse is…

Learn everything you can about your plants.

Be prepared for decisions that will affect all producers of indoor strawberries. Which cultivars to plant must be known. You’ll need to be familiar with planting them. You must be able to feed them. The presence of diseases and pests will be a problem. You also need to be aware of the best time to harvest your fruit.

While one article can’t possibly cover everything there is to know about growing strawberries indoors, it can at least prepare you for the questions you should be asking. Choosing the cultivars of strawberries you need to plant is the first step.

What varieties do you plant?

The best piece of advice for first-time growers of indoor strawberries regarding cultivar selection is to try as many as you can.

Growers can choose from a wide variety of cultivars to plant. The best cultivar, however, for a crop that yields the most and is of the highest quality when grown in a greenhouse, really depends on the region. To determine which cultivars grow the best, growers must experiment.

A good place to start is with some of the cultivars, like Albion, Portola, and San Andreas, that are benchmarks for field production in mild, predictable California climates. These ever-bearing varieties are well suited for year-round production, but not all varieties perform similarly under all circumstances. (It’s acceptable not to use ever-bearing varieties, but you need to be aware that because the hours of daylight won’t be right, they won’t set fruit in late summer for early fall production.)

Albion will assist you in preventing issues with tip burn if you reside in a region with naturally low humidity. Good Brix numbers and consistent fruit quality are produced in Albion. The yield from Albion won’t be as high for most growers as it is with Portola and San Andreas, but it will still be sufficient to make a profit.

Portola is the new industry standard for field production in California, and nurseries across the nation are having trouble keeping up with demand. However, due to its vigorous growth, it is challenging to maintain for the best hydroponic yields. The issue is that this cultivar grows in hydroponic environments a little bit too well.

The Portola’s root system continuously pumps water and nutrients into the plant, keeping it vigorous and producing fantastic yields for growers, but the rapid growth fills the fruit with just a little too much water. Maintaining the fruit’s desired sweetness is difficult.

For production during the winter’s short days, you can try the Camino Real variety if you don’t use overhead lighting. You should be aware that this cultivar is very sensitive to dry air and is vulnerable to tip burn in low humidity conditions.

You should experiment with a variety of cultivars when you first start your greenhouse production. No single cultivar performs optimally in every greenhouse. It’s possible that what works in your neighbor’s greenhouse won’t in yours. To guarantee a crop even in unusual circumstances, always plant more than one cultivar and keep precise records of temperature, humidity, and nutrient mix.

Tip Burn: What is it?

Tip burn is a calcium deficiency that happens during periods of low humidity. The strawberry plant’s leaves continuously release water vapor into the greenhouse’s air when the surrounding atmosphere is dry. These edges appeared burned because they are unable to pump calcium into the edges of their leaves.

But the issue with tip burn’s marketability is not the harm to the plants’ leaves. Additionally burned is the strawberry’s surrounding calyx of leaves. You have a lovely fruit with dead leaves on top, which prevents the strawberry from being sold.

To successfully prevent tip burn, you may be able to fine-tune your fertilizer, but doing so requires making small adjustments almost hourly. Your time and the quantity of berries you must throw away due to tip burn are trade-offs.

What kinds of containers are suitable for growing strawberry plants?

Going with what you have for strawberry container gardening/ indoor hydroponic garden has already been discussed. However, you’ll probably start growing strawberries in a gutter system sooner or later.

The gutter growing technique can be compared to a cocoon that protects your plants. Styrofoam is actually pressed into the gutter. Although lightweight, it is sturdy enough to hold plants. Additionally, Styrofoam helps to maintain a more constant temperature in the growing medium that serves as a substitute for soil.

A plastic liner is placed inside the gutter to shield it from the nutrient solution. A drainage pipe is located above the plastic liner. By doing this, you can both prevent your plants from getting waterlogged and determine how much of your nutrient mix your plants are actually utilizing. You can test both the water you mix with nutrients and the water that drains from your plants.

A plastic grid is placed over the drainage pipe. The plastic grid allows air to flow beneath the strawberry plants’ roots. You then lay weed cloth on top of the wire mesh. This prevents strawberry roots from encroaching into and clogging their feeding pipes.

Your plants are placed on the weed cloth. Before planting them in the gutter, you should probably let them mature in small pots. This enables you to remove unhealthy plants. (You could also plant fully developed plants or dormant runners.) Plants should be placed so that their foliage and flowers hang over the gutter’s edge.

Fruit is protected from moisture by doing this. and benefits the plants by increasing their exposure to light and air movement. Plants should be alternated on either side of the gutter so that there is one plant every six inches (25 cm) or so.

After placing your plants, you will cover them with growing medium. It’s likely that you’ll want to use a mixture of peat moss, perlite, and coconut core. Coconut core can be combined with peat moss because it has a pH that is a little bit too high but is still an excellent absorbent for nutrients for slow release to the plant. The pH of the growing medium is maintained between 5.5 and 6.5 by using peat moss and coconut core in a 1:1 ratio.

The substrate must then be watered in using tap water. While it’s important to avoid burying any plant’s crown under soil, moistening the growing medium enables you to locate areas where you need to add more to fill out the trough. While it is settling in, the plant receives overhead watering. Giving the plants nutrients at this time does not stress them.

The next step is to install irrigation line over the growing medium in the trough between the plants after two or three days of overhead watering. One emitter, usually a 2 liter per hour emitter, is placed for each plant along the line, which is laid down the center of the gutter on top of the growing medium. To prevent soil roots from growing up into the emitter, the emitter must be placed close to the plant but pointed upward.

The growing medium is covered with a white-on-black plastic cloth as the last step in gutter preparation. This barrier prevents fruit from coming into contact with the moist, bare soil, preventing quality degradation. Algae cannot grow on the growing medium because of the black side of the cloth. The plant’s leaves receive light from the sky because of the white side of the cloth.

The Dutch or Bato Bucket system is a container system for growing strawberries and is used by the majority of greenhouse growers.

What modifications to the nutrient medium impact my strawberries’ quality?

Here are some of the ideas you should take into consideration if you’re thinking about starting a hydroponic strawberry farm. We covered this subject in much more detail in Changes in Hydroponic Water Additives That Enhance Fruiting and Flavor of Strawberries.

In order for strawberries to mature, calcium must be separated from phosphates and sulfates. Chemicals that are stored together will precipitate to the bottom of the barrel, never reaching your plants.
When strawberries are developing leaves, they require more nitrogen. You can increase the amount of nitrogen in their nutrient medium, but to ensure that their roots can absorb it, you must reduce the electroconductivity of the medium.

When strawberries are producing fruit, they require more potassium to prevent the flow of sugars into the plant from the developing fruit. However, in order to guarantee that the potassium is absorbed through their roots, you must increase the electroconductivity level of the nutrient solution.
For strawberries to develop their distinctive “strawberry” aroma, sulfur must be present in their nutrient medium.

Other micronutrients can be better absorbed by strawberries with silicon.

Compounds that give strawberries their flavor are formed with the help of boron and molybdenum.

And if you are unable to keep the pH of your growing medium and nutrient solution constant, you cannot be certain that your plants are receiving all of these nutrients. The right nutrient blend for your irrigation water will require careful planning and regular monitoring, but you don’t need to be a chemist to get it right.

What kinds of pest control issues are present when growing strawberries in greenhouses?

The good news about growing strawberries in greenhouses is that you can do so without using harmful chemicals. However, you will need to pursue integrated pest management, which involves controlling insects with insects, if you don’t use agrichemicals.

You almost always get spider mites if you grow strawberries indoors. Spider mites tend to hibernate during the winter months, but they become a significant issue during the warmest times of the year. Introducing predator mites is one method of controlling this pest.

Because one of the predator mites, californicus, can survive on the pollen on the flower, it is possible to apply it to the crop before you notice any signs of spider mites. If you notice disease on your leaves, it’s best to use a more aggressive predator mite like persimilis because spider mites always reproduce more quickly than predator mites. The persimilis is a predatory spider mite feeder, but if you apply it to your plants before they are infested, the persimilis mites will feed on one another.

If you don’t see any signs of spider mite damage, release two or three californicus predator mites per plant; if you do, release five persimilis predator mites per plant.

Additionally, Safer Soap can be used to treat spider mites every three days. This safe miticide must be applied multiple times because it only kills adult mites. Because Safer Soap taints the fruit’s flavor, you should only use it on plants with a serious infestation.

the complex names given to predator mites.

Predator mites are listed in catalogs by their full scientific names, but they are referred to by their species names, such as californicus and persimilis.

The scientific name for persimilis mites is Phytoseiulus persimilis.
The scientific name for californicus mites is Neoseiulus (Amblyseius) californicus.
For the control of spider mites, there are also Galendromus occidentalis and Neoseiulus fallacis.

Although they are natural enemies of spider mites, lacewings, big-eyed bugs, damsel bugs, and six-spotted thrips are not frequently used in greenhouses for strawberry production.

Although whiteflies are not particularly fond of strawberries, you can use Eretmocerus wasps to control them when they invade your greenhouse. To keep an eye on the whitefly population in your greenhouse, use yellow sticky cards. Wasps should be released as soon as you notice white flies.

Although thrips are frequently found in strawberry production indoors, neither the plant nor the fruit are significantly harmed by them. Release tiny parrot bugs as a remedy if you want to (Oreus, such as those in the commercial product Oriline). Parrot bugs are beneficial to have in your crop because they will consume anything smaller than themselves.

What types of diseases affect strawberry crops grown indoors?

Bacterial and fungal disease won’t be a big problem if the humidity is kept under control. Powdery mildew may be controlled by simply removing the affected leaves and applying potassium silicate salts to the plants.

Botrytis, also known as fruit rot, is a problem that can arise even under controlled circumstances. A young fruit develops a tiny spot. Until the strawberry starts to assemble sugar, the botrytis fungus will go dormant and the spot won’t be noticeable. The fungus will then grow quickly, producing spores that can land on nearby plants as well as “fur” that covers the fruit.

Starting with a clean growing area, only bringing in disease-free plants, and keeping your home clean are the keys to disease control. To keep your crop free of pests and diseases, you might want to set up several smaller growing spaces rather than one big one.

When are your fruit harvests?

When it comes to marketing your crop, knowing when to harvest your strawberries is crucial. The cultivar determines when strawberries can be harvested. For example, you want the berry from the cultivar Albion to be almost entirely ruby red with a tiny bit of whiteness on the shoulders. Although 90 to 95 percent of the berry will be visibly ripe, you will never get a fruit that is completely red.

The fruit’s initial color will be orange if you cultivate the Portola cultivar. It reddens up but won’t turn a deep red like Albion. When the orange color disappears and is replaced by a lighter, pinker red, it is time to pick those fruits.

For a fruit with a higher sugar content, you can leave it on the plant a little longer with some cultivars. Certain cultivars require harvesting. Under greenhouse conditions, color is a reliable indicator of when fruit is ready to be harvested, but one peculiarity of greenhouse production is that fruit may be fully ripe with white shoulders. However, you will always need to keep track of your experience with your cultivars in your greenhouse to determine the ideal time for harvest. A Brix refractometer can assist you in selecting fruit at the peak of its sugar content.

Last Words

Growing strawberries hydroponically in greenhouses protects growers from damage caused by extreme temperatures, dry conditions, birds, insects, and diseases spread by the wind. The ability to manage a single planting so that it produces crops every other week for up to six months is provided by these technologies.

Hydroponic growers can easily produce larger crops of strawberries thanks to the most recent understanding of the physiologocial requirements of their plants. When field crops are not available, growers can still produce high-quality strawberries.

The future of strawberry production is indoors, and hydroponics is the most reliable method of feeding strawberries with the nutrients they require. With the help of the information on this website, make sure you are ready for the technical difficulties of growing strawberries, but start with what you have.

QnA guide to plant hydroponic strawberries indoors

Can you grow strawberries hydroponically indoors?

continuous production of fruit Strawberries grown indoors in a hydroponic system are not seasonal, unlike strawberries grown in soil. Make sure your plants are in the right environment and are receiving the proper amount of nutrients in the hydration solution to keep them healthy.

How long does it take for strawberries to grow hydroponically?

Hydroponic strawberry plants need between 90 and 120 days to produce fruit. If your hydroponic growing system is effective and the right kind!

Can strawberries grow in water only?

There is no soil involved in this method of growing. Instead, the roots of the plant are secured in place using an inert medium. Depending on what you’re growing, the root system is directly exposed to water or a nutrient solution as it grows through this medium.

Do hydroponic strawberries taste different?

Furthermore, strawberries grown hydroponically have a more naturally tart flavor since ascorbic acid is one of the natural substances that gives strawberries their tart flavor.

Can you grow strawberries indoors all year round?

Practical Advice for Indoor Strawberry Growing Your indoor berries can be planted at any time of year. Not waiting for the typical growing season is necessary. However, you might need to manually pollinate your strawberries if bees and other pollinators aren’t present.

How many hours of light do strawberries need indoors?

Your berries can receive roughly 17 to 18 hours of light and 6 to 7 hours of darkness per day. This is what? Different species prefer different amounts of light, but for the majority of strawberry species, 16 to 17 hours of light per day will work.
