CO2 system

The system of feeding plants with carbon dioxide (CO2) in the volume of greenhouses.



To increase the yield and improve the quality of crops grown in the greenhouse, a system of feeding plants with carbon dioxide CO2 is used, which is necessary for the life of the plants.

The CO2 supply system constructively consists of flue gas sampling devices from the condenser with subsequent supply to the greenhouse via non-pressure pipelines of variable length along the section with condensate collection tanks.

Distribution networks inside the greenhouse are made of perforated polyethylene sleeves located along the beds with plants.

Carbon dioxide is taken from the condenser by the built-in fan. The required concentration of CO2, the dosing device automatically performs the commands of the ACS.

The system necessarily includes equipment for controlling the composition of the exhaust gases, automatically stops the flow of flue gases into the greenhouse if they contain any impurities harmful to human health.

CO2 value for plants

Carbon (C) is an indispensable component of all life forms. The greater the tightness of the greenhouse, the less air and, accordingly, CO2, carbon dioxide penetrate into it. And it is necessary for the normal growth and fruiting of crops not grown in open field.

In addition to mineral and organic fertilizers, irrigation and temperature conditions, plants need carbon dioxide. He participates in photosynthesis - "metabolism" in the plant body. CO2 content in greenhouses is important for proper plant growth. Gas in the greenhouse stimulates earlier and more active flowering, increases fruiting. This is more important than mineral fertilizers.

CO2 is involved in the synthesis of dry plant matter by 94%, and only 6% is produced using mineral fertilizers. In addition, it increases plant resistance to diseases and pests.

In natural reservoirs and in aquariums, low carbon dioxide content is one of the main factors limiting plant growth. The concentration of CO2 in water and air is similar. The problem is that this gas (like oxygen) dissolves in water almost 10,000 times slower than in air.

If we talk about hydroponics, then in sowing aquariums, fertilization of plants with carbon dioxide was popularized relatively recently. Certain amounts of carbon dioxide are present in the aquarium due to fish metabolism and organic matter decomposition. The CO2 concentration in an aquarium at 20–30 mg / l is harmless to fish and invertebrates and clearly contributes to the development of plants.

A CO2 generator should always be used with other key factors that can stimulate plant growth. Intense lighting and fertilizer increase the amount of carbon dioxide needed for plants.

However, when feeding plants with carbon dioxide, its concentration should be checked to prevent excessive accumulation of gas in the crop. Exceeding the level of 2000 ppm CO2 in the atmosphere of the greenhouse not only inhibits photosynthesis, but also other processes (maintaining a concentration above 3000 ppm can in 2 -3 weeks cause dying off).

What is the use of a CO2 supply system?

Due to the regulated carbon dioxide supply by the system, unnecessary and harmful substances do not accumulate in the greenhouse. The system allows to precisely dose CO2, not allowing the plants to experience “starvation” or overfeed them. An important decision now is to feed the plants with a CO2 generator for plants, which can be bought on our website.
