Plant growth and development is a complex process, strongly influenced by the greenhouse environment. We can distinguish three main processes:
PHOTOSYNTHESIS
Photosynthesis is the process where the plant picks up carbon dioxide from the air and, together with water, creates carbohydrates and oxygen. This process is dependent on the right level of light, carbon dioxide and temperature.
RESPIRATION
In this process, the plant transforms part of the carbohydrates from photosynthesis into free energy used for maintenance processes. The remaining carbohydrates are transformed into plant tissue. The respiration process is highly dependent on temperature.
TRANSPIRATION
Leaf transpiration controls the water and nutrition uptake and the cooling of the plant. Leaf transpiration must be sufficient to enable the leaf to maintain the desired temperature and develop a strong metabolism. The transpiration process depends on light intensity, temperature and humidity.
