Organic gardening in hydroponics – The root system

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 faster 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 Totally Organic Hydroponics, which major benefit is the possibility to grow 100% pure organic garden plants.

Organic gardening – General Notes on Pest Control Approaches in horticulture

Pest Control Approaches

Chemical horticulture fights off invasive pests with specific insecticides. They may be effective and fast-working at the beginning, but their long-term use may result in the raise of the insects resistant to the used insecticide. To kill those, more efforts will be needed, and the use of the different and stronger chemicals may be necessary. Moreover, killing enemies in the garden, any insecticide will inevitably eliminate predator insects (natural control bugs). And their lack will cause multiplying of the harmful pests. Consequently, a gardener will have to search for some other options to defeat the invasive populations.  

Organic horticulture, on the other hand, offers pests control through the studying and understanding their life cycles and peculiarities, as well as through the combined use of such methods as:

-           plants selection (pests and disease resistant plants are chosen for a garden);

-           companion plants growth (planting those crops that fight off pests and insects);

-           annual changing of the plants location to disrupt the reproduction cycles of the invasive species;

-           the use of row covers during the periods of pests migration;

-           employing insects traps to reduce the population of the pests;

-           increasing the number of predator insects and beneficial organisms.

In addition, organic gardeners usually allow some pests to live in the garden, carefully controlling their level though.

All of the mentioned methods have also additional benefits in the organic garden, as fertilization, soil protection, pollination, season extension and water conservation, despite of the fact that their influence and results usually take some time to become obvious. To sum it up it is possible to say that biological and organic pest control can be constituents of the integrated pest management (IPM). Nevertheless, the latter can also utilize chemical pesticides to eliminate harmful insects, although these do not belong to the biological or organic means.

Soil

Soil control and management are the important things in gardening. They offer the possibility to keep the garden healthy and strong, which is the key factor in the prevention of diseases and pests invasion onto the plants. One of the ways to success is providing the garden with humus and organic matter.

Organic gardening in hydroponics – Organic nutrients and growing mediums

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 definitely 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. 

Creating 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 put 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 good 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 important. 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.

Hydroponics Gardening for Organic Vegetables – hydroponics supplies and system over soil grown plants

hydroponic plants receive all the nutrients they need for growing and fruiting from the growing liquid with all the nutrients dissolved in it. Hydroponic nutrients are available in great variety at specialized hydroponic stores. By the way, both chemical nutrients and organic nutrients can be used for the needs of hydroponic gardening. The only thing to remember is that organic fertilizers require more skills, time, and attention to use them effectively.

Hydroponic gardening allows anyone to grow organic vegetables, fruits, and flowers. A little research, learning and training, combined with enthusiasm, will soon bring the first success in hydroponics to you.

Today, there are many ready-made hydroponic systems available on the market. They are not too expensive, but such systems can really help to make an easy start in hydroponic gardening. For the beginning gardeners it is even recommended to choose simple inexpensive hydroponic systems – they are enough to give you the necessary experience. Of course, you can always build you own system to suit all your particular growing conditions and requirements, when you have enough experience and understanding of how hydroponic system works.

If organized properly, hydroponics gardening can even be easier than traditional plants growing. For example, with hydroponic system it is much easier and less time-consuming to test and maintain the necessary pH level in comparison to the regular soil gardening, where even the pH level testing can be a very challenging task, not speaking about maintaining it on the required steady level.  

After all, it is necessary to remember, that in spite of the fact that hydroponics differs significantly from traditional gardening, it is nothing but an alternative approach to grow the same fresh, tasty, and healthy food. Just spend some time to research the topic, evaluate all the benefits of hydroponic gardening – and you will see that there are many advantages offered by hydroponics. Growing healthy organic vegetables without polluting and exhausting fertile soils is definitely one of them.

Starting your own organic hydroponics gardening setup – hydroponics gardening supplies and points to remember

When Starting your own organic hydroponics gardening setup, you should remember that you will need to arrange two beds or layers in your hydroponic garden. The upper bed is, actually, a box to keep the plants in. This box should contain a growing medium for the plants to grow in. You can use perlite, coconut fiber, lava rock, Styrofoam pellets, rockwool or vermiculite for this purpose. The main thing about medium is that it should be able to keep a small amount of moisture for a long time. Experts assure that lava rock is best in this respect.

The lower bed is necessary to keep the water with the dissolved nutrients in it. The water is pumped with the help of an aquarium pump to the upper bed in order to water the plants. This procedure is repeated several times a day at equal intervals, being controlled with a timer.

Gardeners sometimes find it difficult to maintain the pH level of the water, its nutrition rate, and the ration of nutrients at the right level. These are, actually, the key factors, due to which a hydroponic garden or an organic hydroponics prospers. If these three crucial things in gardening are kept in balance with the help of Organic fertilizers, such technique of plants growing is called an Organic Hydroponic Garden.

Organic fertilizers are better for the plants than the chemical ones, as the latter are capable of burning the roots if used in higher concentrations.

When water solution is pumped to the trail with plants, it is partly absorbed by the medium and by the plants roots till saturation point. Consequently, the pumped water, returning back to the reservoir, contains lesser amount of parts per million (ppm) than before. 

Organic nutrients make hydroponic gardening easier, as they do not contain any chemicals, which can change the pH level or ppm of the solution. As a result, many problems, listed among the most common ones of organic hydroponic gardening, get solved on their own.    

It is a common knowledge that the upper part of a plant’s root uptakes nutrients, while the lower one absorbs water. To increase plant’s saturation with nutrients, it is possible to directly add them to the upper part of the roots, which, in the long run, will result in the more efficient organic hydroponics. To introduce such technique into your organic hydroponic garden, you should develop an organic hydroponics system.

The container can be similar as in the hydroponics gardening, or it can be a coir fiber container. It should be half filled with lava rock at the bottom. Then it is preferably to use a medium divider (e.g. coir fiber). The upper part of the tray should contain a mixture of 1/3 horticulture perlite of coarse grade, 1/3 potting soil, and 1/3 of large horticulture vermiculite.

When all this is set, it is necessary to place this container in the grow bed, with water level being a bit lower than the mixture of soils. Such arrangement will ensure the higher efficacy of the organic hydroponic gardening.

Lava rock with the secondary roots of the plants will be submerged in the water, and it will also serve to make this water flow up and moisten the soil mixture. At the same time, the upper layer of medium will be free to absorb the nutrients added directly to the primary roots.

Such hydroponic system saves a gardener from constant controlling and maintaining of the pH level and ppm of the growing medium. Nevertheless, beware of adding too many liquid nutrients to the soil layer: they may leak into the lava rock layer and disarrange your organic hydroponics gardening.

Hydroponics Gardening for Organic Vegetables – Introduction

Hydroponics gardening or growing plants in the growing media other than soil has been known to humans since ancient times. It is known that during the times of King Solomon, people practiced soil-less gardening, which later became known as hydroponic gardening.

The word “hydroponics” is derived from two Greek words: “hydro”, which means water, and “ponics”, which stands for labor. The principles of gardening without the use of soil were developed many and many years ago. Since then this type of gardening demonstrates certain valuable benefits in comparison to traditional growing plants in soil. One of the key benefits is that hydroponic plants grow 30-50% faster than plants, grown under the typical conditions in soil.

Traditional organic gardeners have always demonstrated certain level of contempt for hydroponics as the type of efficient and successful gardening. The followers of the traditional soil gardening consider hydroponics to be a kind of chemical gardening. Organic gardeners have always been pretty pessimistic as to supplying their plants with a balanced and calculated set of chemicals, which is a common practice among hydroponics gardeners. However, such an attitude of wide publicity and professional gardeners to hydroponics had changed after Steve Fox demonstrated his achievements in hydroponics gardening.

One of the key components of hydroponics gardening is growing media, an inert material, which unlike soil, does not supply any chemicals or nutrients to the plant. There are multiple types of growing media used today. The examples are sand, gravel, coconut fiber, perlite, and vermiculite. Amazingly, but even air can be used as a growing media for growing hydroponic cultures under the certain conditions.   

The undeniable benefit of hydroponic gardening is that it protects the fertile soils from exhaustion. Besides, it does not presuppose the use of chemical pesticides and other chemicals, which are extremely harmful for the environment. In general, hydroponic gardening may ensure greater yields and, at the same time, let the fertile soil regenerate itself for further organic farming.

Though hydroponic gardening also uses some of the chemicals to feed the growing plants, all the chemical plant fertilizers and nutrients are contained within the enclosed area of hydroponic greenhouse and do not spoil the open air, water or fertile soil.

Organic gardening – General Notes on organic horticulture Organic gardening systems

Organic horticulture employs the crucial principles of organic agriculture for the successful herbs, fruits, vegetables, flowers and ornamental plants growing. These principles concern the management of pests in the garden, soil composition and conservation, etc.

General Notes

Mulches, Double Digging, compost, Vermicompost, cover crops, mineral supplements and manures are the main constituents of the soil mixture in this kind of gardening in contrast to the commercial farming. Organic horticulture expects to minimize the risk of insects, fungi, and diseases development with the help of maintaining the high quality of the soil. Nonetheless, sometimes it is still necessary to use insecticidal soaps and sprays, pheromone traps, or other pest-control means, created especially for organic farmers.

Experts define five fields of horticulture:

-           olericulture, which stands for the production and marketing of vegetables;

-           pomology that means the production and marketing of fruits;

-           floriculture, which is the production and marketing of floral crops;

-           landscape horticulture that includes the production, marketing, and      maintenance of landscape plants;

-           and finally, post harvest physiology that studies and practices the preservation and maintaining of the quality of horticultural crops

All these areas can utilize the key principles of organic gardening.

Organic horticulture employs the methods and uses data, which have been collected for thousands of years. Generally speaking, this type of gardening is based on the natural, long-term processes and eco-friendly, global approaches, in contrast to horticulture, based on the use of chemicals that speed up the processes and aim at the separate results and reductionist strategies.

Organic gardening systems

There exist various formal organic gardening systems that utilize peculiar methods. They are listed among the general organic standards, but are more specific than them. For example, Rudolf Steiner developed the so-called biodynamic farming. Masanobu Fukuoka, the Japanese writer and farmer, practiced Natural Farming, based on the so-called no-till system for the small-scale production of grain. Finally, intensive and biointensive techniques and SPIN Farming (Small Plot INtensive), developed in France, also belong to the small-scale gardening methods.

A garden in a container or growing box provides healthy, organic, and highly nutritional food. Moreover, it is also the means to share one’s experience, to improve local economy, and to offer better and more sustainable way of living. A small raised bed garden of 32 square feet is capable of supplying tasty, healthy, and organic greens to a family, requiring, at the same time, less water and fewer nutrients if it is based on the postulates of bio-intensive planting and square foot gardening. 

In addition, the existing garden can be improved with the help of composting or vermicomposting. These methods allow getting the best organic fertilizers by reusing organic matter, which provides necessary nutrients to the organic garden. Besides, compost and vermicompost are always an easy way to improve the results.
