Cucumber belongs to the Cucurbitaceae family. Its botanical name is Cucumis sativus (L.) and it is an annual herbaceous plant. There are three main varieties of cucumber: slicing, pickling, and seedless. The cucumber is originally from South Asia, but now grows on most continents.
Humidity: It is a plant with high requirements of humidity due to its large leaf surface. Optimum relative humidity of 60-70% during the day and 70-90% during the night.
Soil: Any type of light textured soils, well drained and with high organic matter. It has a moderately salinity tolerance.
pH: The optimum level is between 5.5 and 7
Carbon dioxide in greenhouses: Levels of 500 to 900 ppm of CO2 produce an increase in production.
Climate: If temperatures during the day oscillate between 20°C - 30°C barely have impact on production, although at higher temperature, higher early production. Above 30°C, imbalances that directly affect the processes of photosynthesis, respiration, and temperatures are observed. Temperatures below 16°C at night can cause malformations in leaves and fruits.
Germination. 27ºC day and night
Vegetative Growth. 21ºC day and 19ºC night
Fruit development. 19ºC day and 16ºC night
