Effects of calcium on photosynthetic characteristics, yield and quality of celery in hydro culture
Jun 07,2024
Celery is an annual or perennial herb, rich in vitamins, minerals, flavonoids and volatile oil compounds, is one of the important edible and medicinal vegetables. In facility cultivation, the development of celery industry is restricted by diseases, lack of nutrients and high residue. Soilless cultivation can provide a good growing environment for crops, reduce the occurrence of pests and diseases...

What is the difference between drain to waste system and recirculating system?
Jun 26,2024
Drain-to-Waste System: How It Works: Nutrient solution is delivered to the plants. Excess solution, which is not absorbed by the plants, drains away and is discarded (wasted). Fresh nutrient solution is prepared and supplied to the plants regularly. Advantages: Nutrient Consistency: Plants always receive a fresh supply of nutrients, ensuring optimal growth conditions. Simplicity: These systems are...

What is the purpose of ebb-and-flow?
Nov 19,2024
The ebb-and-flow, also known as flood and drain, is a hydroponic system technique used for growing plants. The purpose of the ebb-and-flow system is to provide periodic flooding and draining of the plant roots with nutrient-rich water. The cycle typically involves flooding the growing tray or container with the nutrient solution, allowing the roots to uptake water and nutrients, and then draining ...

Which is better, NFT or DWC?
Nov 25,2024
As for the comparison between NFT (Nutrient Film Technique) and DWC (Deep Water Culture), they are both popular hydroponic systems used for cultivating plants. Both methods provide a constant supply of water and nutrients to the plants without the need for soil. However, they have some differences: 1. NFT: NFT is a hydroponic system where a thin film or stream of nutrient-rich water is continuousl...

How does the greenhouse effect affect global warming?
Dec 11,2024
The agricultural greenhouse effect is a natural process that plays a crucial role in regulating the Earth's temperature. It works by trapping heat in the atmosphere, thereby keeping the planet warm enough to support life. However, human activities, particularly the burning of fossil fuels and deforestation, have increased the concentration of greenhouse gases in the atmosphere, leading to an enhan...

Hydroponic cultivation
Dec 24,2024
Hydroponic cultivation is a method of growing plants without soil, where the plants receive their nutrients directly from a water-based solution that contains all the essential nutrients. This technique allows for precise control over the growing conditions, such as nutrient concentration, pH levels, temperature, and lighting. Here are some key points about hydroponic cultivation: 1.Growing Medium...

What is the greenhouse effect model
Jan 20,2025
What is the greenhouse effect model? The greenhouse effect model is a simplified representation of how the Earth's atmosphere interacts with sunlight and heat. It helps explain the phenomenon of the greenhouse effect, which is the process by which certain gases in the atmosphere trap heat and warm the Earth's surface. Here is a basic outline of the greenhouse effect model: Sunlight: The Sun emits ...
