The cultivation of high-quality crops in glass greenhouses is inseparable from these environmental control systems
By using a greenhouse climate control system or automation, your crop production can be greatly accelerated. With this form of environmental control, the greenhouse can be kept constant to provide the best conditions for maximum yield.
The ability of plants to grow and develop depends primarily on photosynthesis. In the presence of light, plants combine carbon dioxide and water to form sugars, which are then used for growth and flower/fruit production.
The management of the greenhouse environment aims to optimize the photosynthesis process of plants, the ability of plants to use light with maximum efficiency.
Greenhouse lighting is more than just eye-catching. Growers looking for the right greenhouse lighting should consider three factors: the type of crops being grown, the time of year, and how much sunlight there is.
Greenhouses typically require six hours of direct or full spectrum light per day. If this cannot be done naturally, supplemental lighting must be incorporated. Auxiliary lighting is the use of a variety of high-intensity artificial lighting to promote crop growth and yield. Hobbyists like to use them to maintain growth and extend the growing season, while commercial growers like to use them to increase yields and profits.
Growers have a variety of lighting options to choose from, so it's important to understand the nuances of different lighting styles. Again, this becomes more manageable with greenhouse environmental controls that can be planned and monitored.
humidity control
As the plants begin to increase their growth rate, you need to slowly reduce the humidity to promote transpiration, which allows more water to flow through the plants. As the plant consumes more water, the elongated cells fill up and carry nutrients to the growing part of the plant.
Humidity should also be carefully observed, as if the temperature in the greenhouse is too high, there is a much greater chance of plant leaves becoming wet. Unfortunately, wet leaves are one of the best ways to ensure fungal infection or mildew. Fungal diseases such as the botrytis pathogen or powdery mildew are common greenhouse culprits. Monitoring and controlling the greenhouse environment means better quality control.
Ventilation and Fan Control
Another easy way to help regulate temperature and humidity is to use vents. Through the use of racks and pegs and ventilation controls, the greenhouse vents can be triggered to open at a set temperature if they start to get hot.
Also, we are measuring relative humidity (relative to the amount of water vapor present in the air, expressed as a percentage of the amount needed to saturate.) It can also be lowered by opening vents. Dry air should be warm, not wet.
We can also trigger the fan using the greenhouse control system. These improve the circulation of the air and help remove moisture from the air. Greenhouse temperature must be increased to achieve the proper balance.
All of this can be controlled from our greenhouse automation computer by using the appropriate greenhouse temperature and humidity sensors. This will help you monitor and regulate humidity and temperature levels more efficiently. Our grower-approved greenhouse environmental control software ensures all levels of control.
CO2 or CO2 Control
Delivering large amounts of carbon dioxide to plants is critical for healthy plant growth. The uptake of carbon from the air by plants is an important part of photosynthesis. Carbon dioxide enters the plant through the stomatal opening through a diffusion process.
CO2 increases productivity by improving plant growth and overall health. Some of the ways in which productivity can be enhanced through CO include earlier flowering, increased fruit yield, and longer growth cycles.
Enter some more technical mathematical models here, but for most greenhouse crops, net photosynthesis increases with CO levels from 340-1,000 ppm (parts per million).
Most crops show that for any given level of photosynthetically active radiation (PAR), increasing CO2 levels to 1,000 ppm will increase photosynthesis by about 50% over ambient CO2 levels.
Adhere to quality control guidelines with our greenhouse climate control system to properly control the CO2 range.
air temperature control
Raising air temperature will increase the rate of photosynthesis to a certain extent. However, above 85 degrees, plants enter photorespiration. This is not the best plant to grow and the plant will start to wilt.
Also, if you can't match higher air temperatures with higher carbon dioxide and light intensity, your plants will be doing more photorespiration than photosynthesis. This will seriously damage the health of the plant.
At some point, the enzymes won't be able to perform their function and will break down and your plants won't build up a healthy metabolism. In conclusion, with our greenhouse temperature control system, balance is key.
Conventional Irrigation and Fertilizers – Fertilizer Control
We like to regularly irrigate and feed the crops in the greenhouse. In today's large commercial operations, fertilization automation can not only help, but all your other farms.
Fertilization Continuous application of water and fertilizer in precise amounts through an irrigation system. This nutrient supply that crops need helps keep yields at their best.
Fertilization is especially useful in the case of drip irrigation. With our automatic fertilizing equipment, water and nutrients are absorbed directly into the roots. Improve the growth rate, resilience and quality of crops.
The system is a more rational use of water and fertilizers. I think respecting the environment and minimising environmental impact is something we can all get behind. We can also use a greenhouse recirculating water system to keep your crops safe.
