That’s what hydroponics is all about.

Hydroponics is the science and practice of growing plants without using soil. Water is the most common medium used instead. There are more technically accurate definitions, to be sure. But for the home gardener, hobbyist and occasional teacher that’s what it comes down to.

But how is such a thing even possible? Don’t plants need soil for nutrition, heat, support, water and all the other things they need to grow and reproduce? Not necessarily.

Plants definitely do need water. But they needn’t get it from the soil, even though that’s one of the most common methods. Even in nature, some plants grow in sand, gravel or even on the surface or underneath a body of water.

Plants need a certain amount of energy, in the form of sunlight and/or heat from their surroundings. But soil warmed by sunlight isn’t the only way to get that. Direct sunlight still works on leaves, the same way it does for plants in soil. Leaving the upper part of a plant exposed to sunlight supported by a string atop a container will allow vital photosynthesis to occur. As with nearly anything in botany, there are exceptions. Some plants survive and reproduce with no light, though they still need some energy to drive biochemical reactions.

Most plants that interest the home gardener or hobbyist do require physical support. Planting them in soil is one common and effective way to achieve that. That’s one of the reasons roots spread and stems are wind resistant. If they hadn’t evolved that way, those types of plant wouldn’t be here to discuss. But artificial aids, such as strings on supports, ice cream sticks glued to the top of a glass and dozens of other methods will work quite well.

One of the most important elements for a plant is without question proper nutrients. Nitrogen, phosphorus, potassium and a host of trace elements (zinc, copper, iron and others) are essential to plant growth. Absorbing those elements from the surrounding soil is, of course, one usual way of obtaining them. But, here again, nutrients can be fed to plants in a number of ways.

Immersing the roots in a container of water that is periodically fed a liquid nutrient solution is one popular technique. There are others. Some hydroponically grown plants are housed in an enclosure that retains moisture well. The roots are then sprayed often with a mister that douses the roots with a nutrient solution. This crosses into the gray area known as aeroponics.

Hydroponics can be used to grow a wide variety of plants: strawberries, tomatoes, lettuce and many non-fruit or vegetable plants, such as orchids. The list is long. Thousands of species can thrive without soil, provided they’re cared for properly. That effort can be fun and instructive. It can also produce beautiful or nutritious plants without many of the drawbacks of soil-grown plants.

Tomatoes, peas, Welsh onions, strawberries and many other fruits and vegetables thrive in a good hydroponic greenhouse. Flowering plants like orchids are equally perfect for this environment.

One of the more challenging aspects of hydroponics is proper light control. Because the medium in which the plant grows is kept wet obviously so when the medium is itself water, algae growth can be a problem. Keeping light from reaching under the surface is easier in a greenhouse. The amount and angle of the light can be more easily controlled with shutters, shades and so forth.

At the same time, hydroponically grown plants, like their soil-based siblings, need ample light to grow well. Greenhouses don’t by themselves produce more light. But they filter and diffuse it, keeping the interior warm and more uniformly lit. They protect the plants from cold exteriors but let in needed sunshine.

Many northern winter climates, for example, have low temperatures but several hours of sunshine daily. A translucent polycarbonate greenhouse wall can easily keep a greenhouse at 100F/38C even in winter temperatures of 15F/-9C.

At the same time, it’s easy to install vents with fans that keep the greenhouse from getting too hot. Temperature control for hydroponically grown plants is just as important, if not more so, as it is for soil-based situations.

Utilizing a greenhouse to ‘keep the benefits, exclude the harm’ provides the best of both worlds. Without one, the only alternative might be using the inside of the home. Using the house can be a big disadvantage for some.

Among other things, a greenhouse – unlike some interior settings – allows for superior lighting and watering system arrangements. Few homeowners will want to give over a room to high pressure sodium or metal halide lamp fixtures. Not everyone will want drip irrigation systems running through the spare room.

With a greenhouse those elaborate systems can be placed precisely where and how it’s best for the plants. That makes it more convenient for the gardener. That aspect is particularly important in the case of hydroponics, since light and water amounts are more critical than in soil-based gardens. Soil-based gardens tend to be more self-regulating without special setups.

By the same token, it’s easier to arrange nutrient feeding systems in a greenhouse. That’s critical in the case of hydroponically grown plants. Given reasonably good soil, plants will simply extract what they need and exclude what they don’t. In a hydroponic setting that has to be arranged by the gardener.

pH control offers the same problem and greenhouses the same solution. It’s much easier for the pH to shift in a hydroponic garden. Because water is everpresent, acidity and alkalinity can change rapidly by large amounts. Ions flow more easily in these circumstances. Working in a greenhouse allows the gardener to set up automatic pH control systems to reduce the amount of manual adjustment needed.

Greenhouses can be constructed or purchased pre-made. They make for an excellent investment for anyone interested in hydroponics. They come in a range of sizes and many are modular so they can be expanded as your garden ‘grows’.

Hydroponics is essentially a branch of horticulture, the practice of cultivating plants. But before one can cultivate well it’s essential to have some knowledge of the needs of plants. That’s where botany proves its worth.

Plants, obviously, are living things. But they have important differences from animals. Chief among those is the ability to absorb nutrients and generate what they need. That is, a plant can absorb sunlight, which provides an energy source. At the same time, it can extract available chemical elements from the surrounding medium, then transform them into food for itself.

Animals, by contrast have to get their food from other sources, either other animals or plants. Sunlight provides them with warmth but not energy to power their functions. There are exceptions, as there are throughout biology. Some extremely small organisms that are sometimes thought of as animals can perform plant-like activities. That’s what makes them borderline cases.

The primary mechanism that most plants use to perform those needed activities is photosynthesis. It can be represented by a simple chemical equation:

6CO2 + 12H2O + light = C6H12O6 + 6O2 + 6H2O

Six molecules of carbon dioxide (6CO2) and 12 molecules of water (12H2O) combine by using energy provided by light. The chemical reaction produces glucose (C6H12O6), a type of sugar. As with animals, the glucose is then later broken down to provide energy for various functions. As a ’side benefit’ (to us, that is) six molecules of oxygen (6O2) and six of water (6H2O) are given off.

That relatively simple chemical reaction allows plants to be self-sufficient. They take in available energy, pull nutrients from the surrounding and produce their own energy and food. It would be great if humans could do the same!

But there’s much more to the plant’s life than just energy production and food consumption. In order to perform those functions plants have to be sturdy and to breathe.

In order to carry out essential processes, the plant has to have a stable structure. Since hydroponics is soil-less, that support has to come from something. Externally it’s supplied by the medium by either supporting trays, strings, rockwool, etc. Internally, the plant’s own cells provide that support, using available elements.

Calcium, for example, plays a large role in forming cell walls. Those eventually build up into tissues that form different types and make features that stand up to gravity, wind and other forces.

Plants, like animals, perform a kind of respiration – breathing. Many of us are taught in elementary school that plants take in carbon dioxide and give off oxygen. That’s true. But they also consume oxygen. They simply give off more than they consume.

They don’t have lungs, but they do have stoma (pores or holes) that allow them to take in CO2 and oxygen and expel some of the O2. That process is called cellular respiration and it’s essential to root growth.

These are only a few of the many fascinating features of plants that give them the ability to provide food, beauty and delightful smells to their fortunate caretakers: hydroponic gardeners.

The first, and most obvious thing needed is the plant itself, either in the form of seed or a pre-existing plant. Luckily, nearly any plant can be grown hydroponically with the proper care. Tomatoes are a favorite starting plant for those new to hydroponics. They drink up large amounts of water anyway and can grow to enormous size in containers without soil.

Since hydroponics doesn’t use soil to support the plant as it grows, some substitute has to be found. Water is the most common medium but it won’t support a growing plant against gravity. The hydroponic gardener uses a number of different methods instead.

A small container with proper supports for the stem will do well. Those supports can be as simple as wooden ice cream sticks or plastic straws glued to the container or secured with string. Kits are available, too, that will supply all the structural components the novice hydroponic gardener will need.

The container size will vary depending on intended use, but a good first try will be about 6-12 inches deep and 2-3 feet wide. A smaller container will work with smaller plants or gardens, obviously. But even a single tomato plant will require room to grow, so better to overestimate than start out too small. Transplanting is a more advanced activity that should be reserved for later.

Fill the container with water. Reserve non-aqueous methods such as perlite or rockwool for later, once hydroponics cultivation becomes more familiar. Start with clean water, but it need not be distilled. In fact, plants grow better in water with minerals. But it should be free of organisms. Sterilize or microwave it to be sure.

The water will have to be aerated. Photosynthesis consumes CO2 and gives off O2, but plants grown in water still need to get oxygen from the medium for cellular respiration in the roots. They’ll quickly use up any dissolved oxygen, so it has to be added artificially. An aquarium pump and filter will do the job, but one designed specifically for hydroponics is best.

As with most plants, light is essential. There are exceptions, of course – some plants don’t need to photosynthesize. Most plants will require 8-10 hours per day of intense light. That’s best supplied by natural sunlight. It’s possible to substitute, at least to a large degree, with artificial lights. Sodium lamps and other types specially made for hydroponics are available.

Plants need nutrients. A good supply of NPK (Nitrogen, Phosphorus, Potassium) fertilizer with needed trace elements is the ticket. But look for those with the right percentage for growing in a hydroponic setting. Too much nitrogen, for example, can easily burn a plant living in water just as it can soil-grown plants. Pre-mixed solutions are the easiest to work with. Ensure that they contain roughly the following elements or compounds:

Substance                    Amount (per 25 gallons of nutrient solution)

Potassium Phosphate              1 tsp
Potassium Nitrate                    4 tsp
Calcium Nitrate                        7 tsp
Magnesium Sulfate                  4 tsp
Boric Acid                                  1/2 pint
Manganese Chloride                1/2 pint
Zinc Sulfate                              1/2 tsp
Copper Sulfate                         1/2 tsp
Iron Sulfate                              1/2 pint

Some water sources may already have some of these. Water testing kits will help you ensure you have the right compounds and pH, which should be close to neutral. Be prepared to change the solution about every two weeks.

A means of keeping the water at the right temperature is vital. Most plants don’t grow well in continual cold. That’s especially true of tomatoes! Unless the climate supplies all the warmth the plant will require, a heating element is essential. A thermometer to measure the temperature will also be needed.

Once you have your plants and the materials to support and care for them, hydroponic gardening is just a little bit of research away.

Hydroponics offers many challenges, but has many benefits both to the plant and the gardener.

Water and nutrient control is more difficult. Light control is more important. pH adjustment is critical. In a soil-based garden, many of these factors are self-regulating, or mostly so. But in hydroponics, these need a little extra care from the gardener.

But hydroponics can actually yield larger fruits and larger output overall. More and larger plants can be produced in a smaller space, for a greater yield. That yield often comes with some efforts that are actually easier. Weeding, for example, is much less of an issue in the typical hydroponic setup. The medium makes it hard for the weeds to get started and they’re easily out-competed or killed when they do.

To derive those benefits, the hydroponic setting has to be arranged, though.

One way to do that is by purchasing a complete hydroponic kit. Kits come with trays and tubing, nutrients, lights, air pumps and sometimes even seeds to get started. They’re especially good for the novice because they package all the ‘ingredients’ needed to assemble a beginning hydroponic garden. Much of the knowledge needed to get started is incorporated in the kit.

But even a kit-housed hydroponic garden needs care. The right nutrients have to be fed to the plants. Even an automatic feeding system will need to be set up, filled and checked. Automatic watering systems, like drip irrigation or under-the-tray tubing will need to be built or arranged. Components have to be monitored for fungi and cleaned or sterilized.

Pest and disease control is required in hydroponic gardens, just as they are in ‘ordinary’ ones. Constant moisture provides a fertile environment for bacteria, mildew and other harmful organisms. White flies, aphids, spider mites, caterpillars and other common garden pests will still need to be dealt with.

Fortunately, there are numerous easy-to-use methods to tackle that problem. Insecticidal soaps, botanicals, fungicides and other compounds run the gamut from traditional 18th century methods which are still in wide use to chemicals fresh from the latest laboratory discoveries.

Hydroponics offers interesting variety, too. Some hydroponic gardeners prefer an all-water system. Trays that hold roots and solutions are fitted with supports from which strings can hold an upright plant. Other gardeners enjoy working with rockwool, perlite and other highly useful hydroponic media.

Some gardeners incorporate all the above in a convenient greenhouse. That allows them to control the light, air, water and other factors much more easily than other settings. Many greenhouses are modular and can be expanded as the garden ‘grows’.

To get started using any method it’s helpful to have some knowledge of elementary botany. Plants have unique needs and hydroponics builds on that base. Knowing what factors they require to flourish will get the hydroponic gardener started off in the right direction.

Get started on your hydroponics garden today. It’s great fun!

Nitrogen is used by growing leaves. But despite the fact that the air is about 79% nitrogen, plants need it in the form of a supplement. The N2 molecule in air is very stable and plants don’t break it apart to use single nitrogen atoms. Phosphorus is essential to root growth. Potassium aids in disease resistance owing to its role in enzyme formation.

The other elements perform a variety of functions. Calcium, for example, is a large component of cell walls and also helps deliver ions to various parts of the plant. Chlorine (Cl) is a component of chlorophyll, an important participant in photosynthesis. Iron is essential to the hemoglobin molecule, which is formed by plants as well as animals, where it helps transport oxygen needed for cellular respiration.

Pre-made solutions are the easiest to work with to supply all the needed elements. As with any compound, dosage is important. For very young plants, such as small cuttings or those that are just germinating, 1/3 teaspoon of calcium nitrate dissolved in a gallon of water is about right, for example. Plants that are flowering will require more, about 3/4 teaspoon.

Water and temperature conditions are important factors, as well, when feeding your plants. Any solution should be fed at room temperature, which should also be the temperature of any water used in hydroponic gardens.

Dry plants should not be fed nutrients. Nitrogen burning is possible. That’s rarely a problem with hydroponics, but one ‘branch’ known as aeroponics, where the plants are grown in air, can suffer that problem.

Allowing any water to stand overnight will help evaporate any excess chlorine from home water sources. Mineralized water is preferable to distilled since it will contain calcium and other useful elements.

Regulate the pH to keep it as near neutral as possible. As plants take up nutrients they’ll tend to make the water alkaline. Add tiny small amounts of sulfuric acid to move it back to neutral. Sodium hydroxide will help shift excessively acidic water back to a neutral pH. Testing kits are available to accurately measure the pH of your hydroponic water.

Hydroponically grown plants are more sensitive to nutrient levels and less able to self-regulate than those in soil-based gardens. In soil, for example, they can take up or shed compounds. Releasing compounds into the water medium doesn’t move them away from the plant. The hydroponic gardener will need to exercise more care to keep plants healthy.

They photosynthesize to produce their own nutrients. They require warmth to keep biochemical reactions going, and going at the right rate. They regulate many processes by the amount of light present, speeding some up and shutting down others.

During photosynthesis plants take in carbon dioxide and water to produce glucose and oxygen. The glucose is used as an internal energy source and much of the oxygen is expelled. But the color and intensity of the light they receive plays a large role in how they do that.

The fact that leaves are generally green and/or yellow shows that those colors are being reflected. The other components of white light (which is a mixture of many wavelengths) are mostly absorbed. But some are taken in more efficiently than others at different growth stages. Wavelengths in the range of the spectrum we perceive as red are used more during growth phases. Blue is absorbed more to produce flowering or fruiting.

Since few hydroponic gardens are simply left out in the sun to take their chances, a lighting scheme is required to assist them in all those activities.

Plants that sit near an open window or are grown outdoors largely self-regulate the wavelengths they absorb, where the whole spectrum is abundant. But those that live indoors can only take up what is available. That makes it important to ensure that they have all they need, both in terms of intensity and wavelength.

Indoor lights are typically less intense (provide less overall energy) and therefore plants may need to be supplemented with natural light. Or, it may be necessary to use special lights to provide the total amount of light energy needed for warmth, photosynthesis and other useful tasks. The mixture will vary from one climate to another.

Indoor lights come in a variety of types, prices and wavelengths, some better for plants than others.

Incandescents provide a lot of heat. They’re relatively inefficient at using electricity for that reason. But they produce strongly at the red end and weakly in the blue range.

Many fluorescents, by contrast, tend to produce greenish light. They’re filled with mercury and the interior coatings that produce light in the visible range may be better or worse at producing a white-approximating spectrum. But, they are much cheaper to use in the long run.

A relatively inexpensive setup can be achieved with a mixture of incandescents and fluorescents. A 30-watt incandescent with a 100-watt equivalent fluorescent provides a good balance of wavelengths. Fluorescents use much less electricity so the wattages can’t be directly compared.

While they cost more, metal halide and sodium lamps make for very good lights for hydroponic gardens. Metal halide lamps produce well in the blue range and sodium lamps provide more reddish light. The bulbs can’t be switched between fixtures so it’s necessary to buy a housing appropriate to each type.

Some newer LED lamps will produce a very broad spectrum and some can be adjusted to favor one wavelength range. However, they’re expensive and many won’t produce the same output as any of the other types.

Plants vary in the intensity they require, as well. Ensure that medium light plants receive at least 1,000 foot-candles. Others will need 2,000 foot-candles (about 20 watts per square foot) or more. A good light meter will tell you how much is being given off, or you can sometimes find the rating listed on packaging or advertisements.

Most lamps should be placed about a foot from the plant to provide the proper intensity. The figure will vary considerably, though, depending on whether incandescents, fluorescents or another source is used.

Plants that receive sunshine will need from 8-10 hours per day. If all artificial light is used, the number rises to between 12-14 hours per day. For some plants and lighting schemes 16-18 hours per day may be needed. The specific number depends heavily on the species of plant.

Rockwool

One of the most popular choices is a material called rockwool. It’s a type of basalt that is specially processed to provide a strong, porous base. It’s mostly inert, so it won’t decay or leach compounds into the water very much. Since it’s porous, it provides good drainage. It’s also lightweight and inexpensive.

Rockwool cubes are often used but small slabs are also available. Pre-drilled holes allow for placing and growing seeds and any cubes containing plants that don’t survive can be easily removed. The cube can be cleaned and replaced with another seed to try again, or simply left out to provide additional space for the survivors. This way, the hydroponics tray can be regulated easily so that there are a limited number of plants competing for air, light, space and nutrients.

Despite its lightweight and porous nature, rockwool provides a very sturdy medium for growing plants. It gives good support to developing roots. At the same time it helps regulate the water temperature by being a good heat conductor. Adding rockwool will alter the pH of the environment slightly at first, but this is easily controlled using a pH kit.

Though rockwool has many advantages for a hydroponic gardener, most everyone will want to experiment with different media at some time. There are many more options available.

Sand

Ordinary beach sand is one common medium. It drains well compared to ordinary clay-infused soil, but in a hydroponic setting it doesn’t do as well as most other possible media. But it’s extremely easy to use and certain plants take to living in sand very well. Certain orchid species in the wild, for example, grow naturally in wet sand.

Gravel

Ordinary aquarium gravel is used in some settings. It provides a strong, clean supporting medium that can also be attractive. But it can crumble and so will have to be cleaned and filtered well before use. Because it’s very heavy, a good pump will be required to keep air and water flowing through the system properly. Otherwise, plant roots may dry out.

Perlite

Perlite is a more popular alternative. It’s a type of volcanic rock that is heated to form small, lightweight pebbles resembling glass beads. It’s desirable for its ability to retain air. Since hydroponically grown plants will quickly deplete any dissolved oxygen, perlite will help the pump keep the water oxygenated.

Vermiculite

Vermiculite is similar to perlite. It, too, is made into small pebbles to provide a flexible supporting medium for hydroponic plants. It draws in water from passive systems by capillary action, helping automate the watering and nutrient feeding tasks. Since it holds even more water than perlite it may exclude air so it needs to be used in moderation. A mixture of perlite and vermiculite is often used for that reason.

Try different options. Experiment. Hydroponics is supposed to be fun!

At the lowest end of the scale some kits offer little more than someone could make for themselves by gathering common household items. But they do implicitly package a little knowledge needed to get started. By including seeds, a tray, some nutrient and maybe even some pH testing strips, they suggest what hydroponic setup is needed to get started. They may include a useful booklet, too.

The next level up usually costs a hundred dollars or so, but the materials are generally much higher quality. A tray that is specifically designed for hydroponics makes it easy to hold seeds in pre-drilled rockwool blocks that come with the kit. A small watering system might be included.

They also usually contain the right nutrients made of quality chemicals. That helps the novice hydroponic gardener get started in the right direction. Nutrient control is a little more difficult in hydroponic gardens and having a pre-mixed solution and clear directions gives your plants the best possible start.

Higher-end kits will include some lights. Which lights, and how many, will depend on price and other factors. A few incandescent bulbs cost very little. A few fluorescent fixtures and bulbs are a little more but still relatively modest in price. Metal halide and sodium lamps kits may run to a few hundred dollars.

Those same higher-end kits will include a more elaborate watering system. Moisture control in a hydroponic garden is more difficult since everpresent water will tend to increase mildew and other fungi. Having a professional watering system will keep water always at the right level and clean of organisms and keep algae levels low.

Since plants are not placed in soil, they will quickly deplete any dissolved oxygen in the water medium. That opens the need for pumping air into the water. Most higher end kits will include a pump and tubing that is designed specifically for hydroponic gardens. Standard aquarium pump setups may work, but the amount and rate of air pumped is different for fish than for hydroponic gardens. Some kits even include a CO2 injector to give plants that extra boost of a compound that is so vital to their growth.

Most kits will include a pH testing kit, and the higher-priced ones will have a digital meter rather than simple strips. They also include pH control powders or solutions as part of the overall package. Some will even include a nutrient meter which can measure levels of needed calcium, iron and other compounds.

Since temperature control is also more difficult in hydroponic gardens, good kits will include a water heater. Heat lamps can warm water and plants, but often too much so. A calibrated water heater will keep the temperature at the appropriate level automatically.

Along with all the needed solutions, tubing, trays and more kits will include any connectors needed for assembly. They also include hanging chains, strings for supporting plants and other useful items. In other words, the kits are just what they advertise themselves as: a complete hydroponics solution.

Necessary Components

In the tabletop hydroponic garden, a planting bed is installed. This can be of any size which is suitable to place according to your convenience. The plants of tabletop hydroponic gardens grow in the growing medium, which is an inert pH balanced solution helpful for providing the necessary odorless support to the plants, especially the roots. This growing medium can preserve moisture with an outstanding capacity. The entire planting system along with the growing system is covered with the help of a transparent and well-vented greenhouse cover.

Moreover, typically a 600ml reservoir bottle is installed in the tabletop hydroponic garden. This aids in automated dispensing of the nutrient solution. When you buy the tabletop hydroponic garden system, you will be supplied nutrient balanced formula specifically formulated for hydroponic system. This is an essential ingredient for the healthy growth of the plants. This formulation contains all the necessary trace elements and minerals in their most untainted form, which is easily soluble in the water.

Selecting the Plants

Although hydroponic plants are healthier than traditionally grown plants, not all plants can be cultivated using hydroponic systems. The same is true when you are using a tabletop hydroponic garden. A wide numbers of people actually prefer to grow flowers in their tabletop hydroponic gardens. If you want to do the same, you may try to cultivate asters, forget-me-nots, California poppies, chrysanthemums, dwarf zinnias, ageratum, candy tuft, and dianthus. Otherwise, if you are interested to grow herbs, fruits or vegetables, you may plow chives, dill, sage, fennel, thyme, parsley, tarragon, rosemary, sweet basil, chili peppers, zucchini, cucumber, tomatoes, carrots and strawberries

Fundamental Environmental Factors

Similar to any other hydroponic system, the tabletop hydroponic garden depends on fundamental environmental factors like water solution pH balanced nutrition, appropriate light in addition to sunlight, humidity, and temperature. Typically it should be placed in light for 10 to 18 hours a day. The ideal temperature must vary between 65°F and 76°F. A certain amount of humidity is very essential for healthy growth and development of the seedlings. Additionally, general care is also important such as pinching off and discarding all the dead leaves, removing any sort of fallen leaves as well as debris from the planting bed.
