In the modern world, you can grow flowers, harvest lettuce, vegetables and other crops not only in a garden or greenhouse, but also in an ordinary city apartment.
To grow plants at home, it is necessary to create artificial climate conditions for them. One of the most effective growing methods is hydroponics. Hydroponics is a technology for soilless cultivation of plants, which has a number of advantages over the traditional method of growing in soil, namely:

• no need to loosen the soil, fight weeds, or regularly water the plantings;
• complete control over plant nutrition;
• In hydroponics, plants easily receive all the nutrients and do not waste energy on developing the root system.

We create a hydroponic installation ourselves

In order to assemble a hydroponic system with your own hands, you do not need to be a highly qualified engineer. The simplest model will consist only of a container, a compressor with a sprayer, seats and an inert substrate. In some of the more complex systems there may be additional elements, but these are mostly minor.

In the article we will look at several types of different hydroponic systems, but first we will talk about the general rules that must be followed when purchasing components.

Rule 1

The tank intended for the nutrient solution must be made of a neutral material that is resistant to fertilizers and does not allow light to pass through.

Rule 2

The volume of the container should correspond to the number of plants and their “appetite”. Otherwise, you will have to refill the container too often.

Rule 3

Among inert substrates, you can choose mineral wool, expanded clay, coconut fiber, perlite, vermiculite or their complexes.

Recommendations for growing plants

In order for plants to grow well and not get sick in unnatural conditions for them, it is necessary to observe some subtleties:

1. You need to constantly add nutrients, but do this only in quantities acceptable for seedlings.
2. With a separate tank and pump, nutrients are added directly to the tank and then mixed with water by running the liquid through pipes. If you are using a structure with compressor aeration and adding water directly, you need to mix the fertilizer before applying it to the plants.
3. In the run-through option, the seedlings are planted in an empty pot, the roots are fixed with expanded clay. In a closed installation with a compressor pumping air, you can use some light soil.
4. Mature bushes need a garter. This will protect the seedlings themselves from damage and prevent the hydroponic structure from tipping over.
5. The fluid level should be checked every day.
6. Monitor the performance of the compressor.
7. Carefully inspect the seedlings. The infected plant must be removed immediately, the water must be completely replaced and, if possible, the entire structure must be rinsed.

If the plants look weak, the leaves have become faded, and the stems have become very elongated, then the seedlings do not have enough light. This problem can be solved by installing additional fluorescent lamps or by ensuring that the device is placed in a place with good natural light. Wide window sills or stained glass windows are perfect.

ACS system

This instruction will help you create a budget system from scrap materials.

You will need:

• 2 plastic containers + 1 lid;
• disposable plastic cups;
• 1 plastic and 1 rubber tube (the plastic drain must have a larger diameter);
• pump with a capacity of 380 l/h (we recommend considering the SP-650 model from the Resun brand);
• knife or drill for punching holes;
• Azud seals and hot melt adhesive;
• 2 G-fittings. You can take connecting elements from high-strength plastic and save money without losing quality. The Azud brand has these.

It is very easy to assemble such a system. To do this, follow the instructions:

1. It is necessary to make holes in the lid of the container for seats.
2. Cut holes in the bottom of the glasses for the roots.
3. Place the upper drawer on the lower one, then one end of the rubber hose should be removed through the cut hole.

4. In order to supply the nutrient solution from the lower tank to the upper one, you need to purchase a pump and attach a 10-15 cm long hose to it. The pump must be placed in the lower tank with the nutrient solution.
5. The end of the plastic hose should be cut at a 45 degree angle and installed with the cut side down. To seal the holes, you must use special gaskets or hot melt adhesive.

6. In the upper container, on opposite sides diagonally, there should be two holes for supplying and draining water. Afterwards, all that remains is to pour the nutrient solution into the lower tank, turn on the pump and check if there is a fountain from the tube (to test the drain for leaks).
7. We place the glasses in their places. The hydroponic system is ready!

DWC installation

DWC is a deep water culture method. With this method of cultivation, the root system of the plant is completely immersed in a nutrient solution, which is constantly aerated. An example of such a system is a ready-made AquaPot installation. It is excellent for growing large annual crops. Thanks to its compact size, it can easily be placed even on a windowsill. All that is needed for high yields is to change the solution every 7-10 days, monitor the pH and EC indicators. If desired, you can assemble a similar installation yourself.

For this we need:

• container with a volume of at least 20 liters with a lid;
• mesh pot with a diameter of 16 cm made of non-toxic high-strength plastic;
• sprayer ASC-02;
• single-channel compressor.

Build process

It is necessary to make a hole in the lid of the tank to match the diameter of the pot. Directly under the cover, another hole should be made for the wire of the compressor connected to the aerator. The connection points should be sealed.

The germinated seed in a rockwool plug should be placed in an inert substrate such as expanded clay drainage or rockwool. Accordingly, place the substrate with the seedling in the planting area. 12-15 liters of nutrient solution are poured into the tank. The compressor in such a system must operate 24 hours a day. The nutrient solution must be changed once every 7-10 days. Remember that when growing hydroponically, it is important to control the pH and EC levels of the solution.

What can you grow this way?

Unfortunately, not all vegetable crops grow equally well without soil. The most popular types for which hydroponics is used at home are cucumbers, tomatoes, legumes, various greens, and leafy crops. In a word, these are plants with edible “tops”.

Root crops need soil to fully develop and acquire the necessary taste qualities.

Soilless cultivation is also suitable for indoor flowers, ornamental annual crops, and seedlings. It is these seedlings that are usually sold in specialized stores.

Growing seedlings hydroponically allows efficient use of greenhouse space

Drip irrigation system

It should be considered as temporary help for plants, especially when you are not at home. If assembled correctly, this system will be able to irrigate plants without your presence. Often, growers use drip irrigation to irrigate their pets grown on coconut or any other inert substrate.

Here's what you'll need to create a drip irrigation system:

• tank for nutrient solution (depending on the number of plants);
• two 16 mm main pipes made of durable plastic;
• microtubes;
• seals;
• microfittings;
• G-fitting;
• punch.

How to assemble drip irrigation:

1. Make a hole in the tank for the main main pipe (seal with a sealant);
2. Place lines from 16 mm pipes;
3. Using a punch, make a hole for the microtube
4. Next, the micropipe is connected using a microfitting to the main pipe;
5. Droppers are installed;
6. A pump should be placed in the tank;
7. At the end of the line we install a drain valve.

You can assemble a drip irrigation system yourself. You won't have to look for components for a long time. Everything you need for assembly is in our store.

Advantages and disadvantages

If we talk about the advantages of hydroponics, we can list many advantages of this method.

• Compact planting. Plants can be planted thicker than when grown in the ground, and in several tiers. This immediately increases the usable area of ​​the greenhouse or window sill several times. And leave the vacated beds for those crops that feel better in the ground.
• Easy to care for. Having hydroponic installations, the gardener does not have to dig into the ground, loosen it, fertilize it, dig it up and pull out weeds. And in apartment conditions, such “clean” growing is especially attractive.

We recommend: Preparing the garden for spring work

The hydroponic method is also applicable to indoor plants

• No need for watering. Since the plants feed on the solution, there is no need to water them, nor do you need to monitor the condition of the soil, preventing it from drying out. This is very convenient for those who cannot care for plantings regularly.
• Reducing the risk of disease. Most of the pests and various microorganisms that cause plant diseases live in the soil. If you use a clean substrate and regularly update the solution, they will hurt less.
• High yield. Hydroponics at home allows you to obtain excellent yields, incomparable to the amount of produce that is obtained from the same area of ​​soil.

Spending less energy on developing roots and obtaining food, plants use them to produce fruits

However, this method also has disadvantages, the main one of which is the large initial costs of money and time for high-quality arrangement of “plantations”. Another disadvantage is associated with the quality composition of the concentrated products from which the nutrient solution is prepared. Some manufacturers introduce nitrates and other substances that are not the most beneficial for human health, which activate plant growth, increase productivity and protect them from diseases.

But the same substances get into them when grown in soil using fertilizers. Therefore, the quality of the product depends entirely on the integrity of the farmer or agricultural enterprise, and not on the method of cultivation. If we are talking about personal farming and the production of vegetables for yourself, then you have the power to choose a reliable manufacturer or create working solutions yourself. So hydroponics, the harm and benefit of which are relative concepts, is the choice of those who appreciate its benefits.

DIY aeroponics

The term aeroponics refers to growing plants in a soilless environment. Only unlike hydroponics, their roots are in the air and irrigated with a nutrient solution supplied from nozzles.

Accessories:

• large capacity 70-100 l;
• PVC sheet;
• mesh pots.
• water pump with a capacity of 3000 l/hour;
• part of metal-plastic 50 cm;
• 2 adapters for metal-plastic;
• injectors.

Assembly diagram

1. One end of the adapter must be screwed into the pump, and the other must be connected to the turntable through the barrel;
2. Place the structure at the bottom of the pot;
3. Cut a plastic lid to the diameter of the top of the pot;
4. Make holes in the lid for seats;
5. Perforate the pots using a soldering iron;
6. Close the central hole with a plug;
7. All that remains is to add the substrate to the pots, place the plants, fill the container with a nutrient solution with an adjusted pH level (5.8-6.2) and turn on the pump.

Adviсe:

1. pour no more than 50 liters of solution;
2. select a watering mode lasting 15 minutes at intervals of 30 minutes;
3. use large expanded clay as a substrate.
