How to grow herbs in hydroponics at home

A rare hostess did not dream of having fresh greens always at hand. And if indoor flowers - a familiar phenomenon, the dill and lettuce on the windowsill is not so often found in an ordinary apartment. Nevertheless, there are technologies that allow you to easily grow not only beautiful, but also useful plants. In this article we will talk about hydroponics - a method of growing greens at home.

Fresh greens any time of the year

Hydroponics is an old, though not very well-known, groundless method of growing plants. The name itself speaks about the specifics of the method: translated from Greek, it means "working solution".

When grown hydroponically, the roots of the plant are in a homogeneous solid substrate of organic or artificial origin. All the nutrients green scoops out of solution, where the container is immersed with the substrate. For each type of plant there is a separate solution with the necessary set of batteries.

What you need for growing greens

To grow dill and other plants in hydroponics, it is necessary to prepare all the components of technology. It consists of two elements.

Installation

Hydroponic installation includes containers for planting and supply system nutrient solution. There are many types of such installations, adapted for industrial or individual use. Equipment for hydroponic cultivation can be bought or assembled by hand. If it is decided to make the construction independently, you will need a double container (two separate containers can replace it), a water tank, a pipe, an aquarium pump and a timer that will control the entire working system. These details will be enough to establish the cultivation of greenery on the balcony; still need to maintain optimal temperature and lighting.

If there is no desire or opportunity to assemble a hydroponic plant for growing greens personally, you can buy it by ordering via the Internet. The principle of the factory systems is the same, except that the purchase will look more compact and easier to use.

Solution and Substrate

When the growing plant is ready, it remains to take care of the solution and substrate. The substrate that fills the pots of plants serves to support the roots. He himself is absolutely sterile, that is, does not contain any nutrients. It is important that the substrate is not exposed to moisture and chemicals dissolved in water. The solution is usually bought in gardening stores. This is a prepared liquid that contains all the necessary trace elements for the growth and development of a certain type of greenery. Since each plant requires an individual nutrient medium, the composition of the solution for different species will vary.

Preparing for landing

Before landing, it is necessary to determine the place where the hydroponic installation will be located. As a rule, it is a window sill or a balcony. In addition to food (which is provided by the system), plants need sufficient lighting and a constant, comfortable temperature for growth. These factors need to be considered.

Substrate selection

As mentioned above, the substrates are divided into organic and artificial. The main property of any of them - resistance to the constant influence of water and chemical elements. They also should not release any substances, as the plant nutrient is strictly calculated in advance. Here are some of the most common substrates:

• expanded clay - These are pieces of clay, caked under the influence of a temperature of 1200 ° C. There are no minerals in it, but expanded clay can lower the pH of the solution. This type of substrate is suitable for reusable use, you just need to rinse it from the remnants of the solution and clean the roots. Before first use, claydite is also washed under running water to avoid impurities;

• mineral wool - one of the cheapest and effective substrates for hydroponics.However, it has its drawbacks. Working with mineral wool requires caution, as it contains microparticles that irritate the skin. It is necessary to be afraid of hit of this substance in eyes and airways. It is also a biodegradable substrate, and proper disposal of mineral wool can cause difficulties;

• coconut substrate. In its composition - coir and ground coconut shell, so it is completely safe for the environment. After use it can even be poured into beds as fertilizer. As a support for plants in hydroponics, it is considered one of the best, because it can accumulate minerals and nourish them for a long time. It also retains water well and gives oxygen access to the roots;

• vermiculite and perlite. These two substrates are recommended to be used together, as they have complementary properties. Vermiculite makes the composition of the soil loose and absorbs a lot of water. Perlite complements it, this substrate of volcanic origin also perfectly retains moisture and does not interact with chemical fertilizers.

Planting seeds

As a rule, hydroponics requires the initial germination of seeds. Seeds are germinated in the soil or its analogue (for example, in peat), watering in advance with prepared solution. When a seedling has one or two true leaves, it means that the root system is already quite developed. This plant will transfer planting in a filler without loss. For transplantation, the grown seedling is removed from the pot along with the ground and the roots are gently washed. Then, holding the plant, fall asleep straightened root system substrate. It is necessary to plant at such a depth that in the future the roots do not touch the solution - moisture and nutrients will rise up through the pores of the filler in sufficient quantity.

Some modern hydroponic systems make it possible to dispense with a transplant and sow the seeds immediately into the plant. But not all manufacturers offer such capabilities.equipment.

Preparation of the solution

The solution is prepared according to the manufacturer's recommendations, observing the exact dosage. For growing lettuce and other greens in hydroponics at home, they take a concentration of 1.25 above the average. The solution consists of a complex fertilizer and calcium nitrate. For accurate dosing of fertilizer, you can use a medical syringe. The required amount is diluted in 1 liter of water. Calcium nitrate is diluted in a concentration of 25% for soft water (250 g of substance per 1 l of water). These are two basic elements for a common solution.

Features of care for greens in hydroponics

The main difficulties and concerns of the owners of hydroponic systems are to maintain the external conditions for growth. In addition, the installation itself requires care. Here are the basic requirements:

• The nutrient solution should be completely replaced every three months. This will help to avoid changes in the concentration of mineral substances under the influence of external factors;
• Do not allow foreign objects to enter the solution.This also applies to dead parts of the plant - they need to be cleaned in a timely manner;
• the optimum water temperature should be maintained (20 ° C). If the installation is on a cold window-sill, it is recommended to build a stand or a tray for it.

Hydroponics is a reliable method of growing greens at home, which does not require much effort and has proven itself among amateur gardeners.
