Question

Visit a green house if there is one near your place. Observe how they grow plants. Find out how they regulate the amount of light, water and carbon dioxide to grow the plants.

Answer 1

1. Light Regulation:

   • Use of Shading Nets: To control the amount of sunlight entering the greenhouse.
   • Artificial Lighting: Additional lights may be used to ensure plants receive adequate light during low natural light conditions.

2. Water Regulation:

   • Drip Irrigation Systems: Efficiently delivers water directly to the plant roots.
   • Sprinkler Systems: Evenly distributes water over the plants.
   • Humidity Control: Humidifiers or misters may be used to maintain the desired humidity levels.

3. Carbon Dioxide Regulation:

   • Ventilation Systems: Ensures proper air circulation and CO₂ levels.
   • CO₂ Enrichment: Some greenhouses use CO₂ generators to increase the carbon dioxide concentration to enhance plant growth.
