Thinking of hydroponics kits as of something too hard some people are reluctant to try it. As a matter of fact, it is not always right. With hydroponics everything really depends on the gardener. He is the master, who can make the process either as simple or as complicated as he wants. A beginner can succeed in it, or an experienced gardener can be faced with serious difficulties. The clue is in the system, either built or bought by the gardener. Anyway, there is no the least reason to hesitate. And the final result is really a worthy tribute.

Hydroponics is a technique of growing plants without soil, using a hydroponic nutrient solution instead.

Though there are various methods to hydroponics, we will discuss the simplest and the most frequently used ones. The key elements of hydroponics are given below.

SYSTEM TYPES

Depending on the way of delivering nutrient solution to the plants roots passive and active systems types are defined in the hydroponics.

Passive systems are the simplest and, therefore, recommended for the beginners. This type implies that the nutrient solution gets to the plant through a wick or through the growing medium (rocks, gravel, vermiculite, etc.). This easy method has, but, a weak-point: the solution cannot circulate, which requires additional care and attendance of the gardener.

Wick System is a vivid example of a passive system.

Active systems suggest the circulation of the nutrient solution with the help of the pumping equipment. Being pumped into the system, the solution nourishes the roots and then drains down back into the reservoirs due to the gravity, and it is later reused. Such systems may need more efforts to initiate their work, but they do not require significant maintenance.

Ebb and Flow, Aeroponics, Nutrient Film Technique (NFT), and Top Feed belong to the active systems.

NUTRIENT SOLUTIONS

Nutrient solution is another vitally vital element of hydroponics. The first thing to do here is to take as much tap water as required by the type of your system. To get rid of chlorine just let the water stay in the buckets for 24 hours.

The next step you should take is to dissolve nutrients in the water. They come either in liquid or in powdered forms, the latter one being usually less expensive. Different mixes of the nutrients are always available online or in the garden supply stores. It is recommended to strictly follow the instructions not to exceed the amount of the nutrient needed.

Prior to using nutrient solution be sure to check its pH level, which can be neutral (7), acidic (0-6), or alkaline (8-14). pH level depends on many things as the chemical composition of the water in your tap, its temperature, light, etc. The optimal pH for the majority of plants is about 5,5- 6,5. To check it you can use testing kits available in the majority of garden shops or with the help of the electrical tester.

Relying on the testing done you may need to adjust pH of the solution. To do it you can use pH adjusters, some of which lower pH level, while others increase it. On the other hand, some gardeners prefer to use baking soda (one tablespoon per three gallons of the solution) to lower pH level of too acidic mixture, or white vinegar if it is too alkaline (one tablespoon per four gallons). Though this process needs some practice to be successful, it is still an effective alternative way of adjusting solutions, which works well for many gardeners.

LIGHT

To achieve proper growth rates plants require sufficient lighting. Natural sunlight is ideal, but not always possible to get in the necessary amount; thus, artificial lighting is a common practice in hydroponics. Grow lights or artificial horticultural lights are usually present in nearly any hydroponic system. But, they can be quite pricy, so it is better to shop around before making the final choice which one to buy.

We welcome everyone, who is willing to grow herbs, plants and flowers inside the house. It is so easy to get lost among the large number of sources about the indoor gardening; that is why, we will do our best to give you the most vital and easy to know information before you start.

HOW TO CHOOSE A PLACE FOR HYDROPONIC GARDEN?

The very first and the most vital task for you to do is to choose a place in your house, where you will make a garden. Really, any free space, whether it is a closet or a basement, will do. You will need 250 Watt – 400 Watt high pressure sodium or halide light for not less than about 6 feet (150-180cm) of grow room height to avoid the growing place overheating. These lights are enough to properly light up the space of about square meter.

 WHAT DO I NEED TO START INDOOR GARDENING?

Hydroponics belongs to those avocations, which, along with requiring much time, knowledge, and skills, will need excellent equipment to be successful and satisfying. Here belong inert hydroponic media, hydroponic system, either natural or artificial source of light, hydroponic nutrients and, really, plants. 

COULD YOU, PLEASE, CLARIFY WHAT HYDROPONICS MEAN?

Hydroponics is an art of growing plants using a nutrient rich solution instead of soil.

ARE THERE ANY REQUIREMENTS TO THE PLACE FOR HYDROPONICS?

The trickiest and the best thing about hydroponics is the possibility to grow plants everywhere: inside or outside the house, as well as in a greenhouse. To tell the truth, any plant can be grown with the help of hydroponic method, though some herbs may require more skills from the gardener to grow well.

 WHAT DOES AEROPONICS MEAN?

Aeroponics is another way for the gardeners to get rich crops. In this case the infusions of oxygen into the nutrient solution are used to hasten plants growth.

ARE HYDROPONIC PLANTS ORGANIC OR NOT?

For the time being, the question whether hydroponics is organic remains debatable for many people. But, a large number of gardeners are certainly the advocates of this statement. Hydroponics uses the methods of direct supplying all the necessary minerals to the plants without growing them in the soil. It is a proven fact that the yields obtained in this case are much richer and of better quality than those received from any other organic method of plants growing. 

WHAT IS THE KEY BENEFIT OF HYDROPONICS OVER SOIL CULTIVATION?

Having the possibility to adjust the rate of nutrients required for plants optimal growing, hydroponic gardeners manage to achieve the best growth rates and increased crops volume for the shortest period of time.

IS IT RIGHT THAT HYDRPONIC PRODUCTS HAVE DIFFERENT TASTE THAN THE SAME PRODUCTS, GROWN ON SOIL?

Taste, flavor, and nutrition rate of hydroponic produce often surpass those of the soil grown produce, due to the fact that nutrients, necessary for the plants, are easily accessible for them at the time when plants need them the most. 

WHAT MINERAL ELEMENETS IN PARTICLUAR ARE NEEDED FOR PLANT GROWTH?

To succeed in the plants growing a gardener should know what elements are essential for the plants. Here belong those provided by water and air: oxygen (O), hydrogen (H), and carbon (C); several others are available for the plants from soil or growing medium: calcium (Ca), iron (Fe), phosphorus (P), magnesium (Mg), nitrogen (N), sulfur (S) and potassium (K); as well as some others, determined as essential not so long time ago: zinc (Zn), molybdenum (Mb), copper (Cu), chlorine (Cl), manganese (Mn) and boron (B).

Temperature is a gauge for optimum production for every plant. When plants are exposed to extreme ranges of temperature, stunted growth and poor fruit yields are the result. Plants have specific temperature ranges for their ideal growth. Warm-season vegetables and most types of flowers have 18o C and 260 C as an ideal temperature range. Cooler season vegetables like lettuces have a 10o C to 18o C range.

Garden Climate Controller

Environment greatly affects plant growth. Environmental factors such as temperature, climate and CO2 levels are just examples. Garden climate controllers give you control over this variables and keep them at ideal ranges for optimum growth of plants.

Basic Garden Climate Controller

The cheap and basic garden climate controller usually control temperature and humidity and turn exhaust fans when needed. CO2 controls could be installed together with them for a small additional charge. This combination is more economical allowing you control over all environmental factors without spending hundreds of dollars for more sophisticated setups not needed. Indoor hydroponic garden systems can be maintained with this basic setup.

Complete Garden Climate Controller

Complete control over CO2 system is another advantage presented by the use of the complete hydroponics garden climate controller. Controllers also allow for coordinated infusion of carbon dioxide with exhaust fans giving minimum waste of CO2.

Other “extras” found with garden climate controllers:

Additional outlets activates when lights are off allowing a “night mode” setup.

Flood Sensors that prevent common gardening mishaps by shutting down the system.

Photo sensors recognize natural sunlight and power ups the “night mode.” This makes the setup more efficient and economical as grow lights are only utilized when needed.

The use of organic plant nutrients instead of the man-made chemicals in the hydroponic garden eases the work of a gardener. The matter is that the absence of synthetic chemicals eliminates the problem of ppm amount and pH balance of the water. If there is no need to calibrate nutrients, to check pH level of the water, and calculate fertilizer’s amount, a beginner of the hydroponic gardening will certainly make no mistakes, which means many problems may never occur.

A dual root growing system is made by special composition of the medium in the container: the upper part of the medium is soil or soil substitute, and organic nutrients can be supplied directly to this upper part; the lower half of the medium is some porous material, which retains water, but to which no nutrients are supplied. 

Making an organic hydroponics system, a gardener may use a standard hydroponic grow container, though a coir fiber container will suit too. The preferred material to place at the bottom of the box is lava rock, which perfectly keeps water. Lava rock is then covered with a thin layer of loose rockwool or coir fiber to divide both medium layers and prevent them from mixing together. The upper half of the container should be filled with a mixture of 1/3 potting soil, 1/3 coarse grade horticulture perlite, and 1/3 large-sized horticulture vermiculite. Such arrangement ensures the upper capillary action of water and protects the bottom of the grow bed from the occasional mixing with any organic particles. 

Using a standard plastic hydroponic grow container one should place a plastic screen lining inside the grow bed, fitting it well at the bottom and on the walls of the container up to their top, also with the aim to protect the water from the small particles in the medium mixture. It is also possible to use a hydroponic container with tiny holes.

One more excellent choice for the use of organic gardening methods in hydroponics system is coir fiber containers. The filling is the same as described above with the thin layer of loose or strand coir fiber between the two types of medium. 

Such box is then set in the grow bed. Note that the level of the pumped water should be a bit lower than the soil mixture. The secondary root system will be submerged into the water along with lava rock and promote the capillary water flow up into the soil. The lower half of the medium may be watered on a regular hydroponic basis, while the upper one can be moistened just once a day. 

This system allows a gardener to supply nutrients right to the upper part of the medium, where they are vitally vital. At the same time, the whole medium structure will be perfectly moistened by the pumped water and the plants will also have constant supply of oxygen and CO2, drawn into their root systems. Finally, proper amount of CO2 will improve the absorption of nutrients by the upper parts of the roots. 

Plants, growing in the containers, will develop two types of the roots: the upper one, which will uptake plant nutrients from the upper part of the medium; and the lower roots, which will reach the lava rock part of the growing medium.

The upper root system is primary; it includes web-like thin roots that look similar to those that develop in the plants grown in the standard soil. They absorb multiple nutrients, thus ensuring the flourishing of a plant and its normal growth. The lower roots that are secondary will grow in the lower part of the medium (which can be lava rock, sand, gravel, perlite or pumice). These look typically to the hydroponically grown plants: long, rope-like, and stringy. These roots mainly absorb water; in addition, they receive much oxygen between watering cycles, which leads to the improved nutrients metabolism and quicker growth.

These days hydroponics gardening gains more and more popularity in different parts of the world. More and more people become fascinated with this way of plants growing. Due to the constantly increasing interest in hydroponics, new methods and techniques of this gardening type appear. They are all aimed at the easing of the process of plants growing, improving the fruits, vegetables, and greens quality and taste, as well as at the making the whole process as eco-friendly as possible. Indeed, the new techniques try to solve the problem of hard-to-dispose used materials (as rockwool) and chemically-laden water and other wastes. Moreover, the primary goal of today hydroponics is to use exclusively organic materials, which offer the benefits in the crops quality and work of a gardener. 

Not so long time ago gardeners were amazed by such hydroponics methods as Nutrient Film/Flow Technique, Ebb and Flow, Aeroponics, and even Semi-Organic Hydroponics. These days the leader of this gardening is Really Organic Hydroponics, which major benefit is the possibility to grow 100% pure organic garden plants.
