Hydroponic enterprise belongs to the category of promising business in the field of crop production, which is very important in our country. Hydroponic cultivation of watermelon and other crops can be carried out year-round.
In the hydroponic system, the classic soil is replaced by a special substrate. Compared to the traditional and well-known to all gardeners growing plants in the soil, hydroponic technology has a number of undeniable advantages, which are obvious to all growers:
- the plant is provided with all the substances and vitamins necessary for growth and full development;
- the culture grows stronger and healthier, and indicators of flowering intensity increase several times;
- the soilless environment is characterized by the absence of pests, does not support the development of diseases such as rot and fungal infections;
- no need to use chemicals for preventive and protective measures;
- the root system of plants does not experience a lack of oxygen, and is also not able to experience negative effects from an overdose or lack of fertilizers;
- with a minimum cultivation area, it is possible to obtain maximum productivity year-round, even at home.
A correctly developed and competent business plan allows you to optimize production and get decent profit when growing vegetables or berries with a view to further implementation. When developing a plan, it is very important to consider the main points that are presented:
- a place for growing plants;
- botanical and varietal characteristics of the cultivated crop;
- features of the sale of finished vegetable or berry products;
- analysis of the flow of financing and expenditure.
The main reason for the worldwide popularity of hydroponic technology is its high economic efficiency, which is obtained by increasing yields with significant resource savings.
Hydroponics: growing seedlings
Liquid fertilizer costs
Hydroponic growing technology involves the use of liquid fertilizer. Qualitatively and correctly prepared nutrient solution allows you to fully provide the plant grown with the necessary elements for full growth and development. Any type of nutrient solution for plants grown on hydroponics must necessarily contain all the nutrients necessary for growth and development. Products from the category "liquid fertilizers" sold in our country have proven themselves in hydroponic conditions.

Quite often, when growing plants on hydroponics, Kemira-Hydro fertilizer is used. When choosing fertilizer for a nutrient solution, the molar mass of nutrients must be considered. It is imperative to monitor the performance of batteries so as not to exceed the concentration of micro and macro elements introduced into the substrate.
If necessary, add settled water to the system, which will save the volume of the nutrient solution. Every three months, it is recommended that a complete nutrient solution be replaced in the hydroponic growing system.
The equipment involved in hydroponic cultivation may be different. You can use ready-made schemes and make a system with your own hands, or you can use an industrial highly productive installation, which most often becomes the choice of the owners of the greenhouse. Before choosing equipment, it is necessary to evaluate different options, as well as consider both advantages and disadvantages:
- when growing undersized plants, the most appropriate choice is to use a recirculating NFT system or flooded-drained gravel channels, periodicals;
- tall or too demanding care crops, it is desirable to grow on non-recirculation systems based on the use of the substrate.
It should be remembered that the use of recirculation systems does not imply the use of water with a high level of dissolved salts. Water of insufficient quality is mandatory to be purified by means of quite expensive filters operating on the principle of reverse osmosis.
As a rule, it is necessary to prepare the area for placement in advance, in accordance with the business plan and the developed schemes. An important role is given to the preparation of a quality substrate, which can be represented: perlite, vermiculite, expanded clay, mineral wool, coconut fiber, chemically neutral fibers in the form of nylon, polypropylene, capron or foam rubber.
Self-manufacturing system is based on the use of the following necessary components:
- pump or pump and compressor;
- trays or pallets;
- planting pots;
- lamps for illumination in the winter.
To install a hydroponic system, it is advisable to use a special metal cabinet or make racks. When purchasing a ready-made system, you must carefully study the attached instructions. The basic design and system of industrial cultivation includes a system for heating and cooling, special panels, a water treatment system in the form of a collector and storage. It may also be necessary to purchase backup systems provided by power generators for continuous operation of the recirculation system.
The drip irrigation system delivers a nutrient solution under the base of plants with a predetermined interval. Such systems are ideal for growing cucumbers, tomatoes, peppers and eggplant. Flowing hydroponic systems are characterized by the movement of nutrient solution through channels with the plant root system located. This system has proven itself in the cultivation of lettuce, basil, parsley, fennel, dill and other green crops. Drop-flow irrigation in hydroponics is most often used in the cultivation of strawberries and strawberries.
How much money to invest and what kind of profit can be expected are the main questions of plant growers starting to master hydroponic cultivation technology. To calculate the profit, it should be remembered that most crops grown under such conditions have maximum yield indicators, which can be obtained from each square meter, regardless of the number of plants planted. As practice shows, there are no significant differences in planting density between hydroponics and classical soil. With an increase in planting density, crop loss and a decrease in overall yield may be observed.
It is also important to remember that cultivating early ripening varieties requires consideration of turnaround times. Therefore, with year-round cultivation in hydroponics, you must first calculate the profit for the whole year according to average yield indicators. It should not be forgotten that an important aspect of crop production is the quality of products, labor and packaging costs for the purpose of further implementation.
