What is the greenhouse effect
When sunlight for cladding greenhouses, they are often discouraged and released part of the absorbed radiation cladding material. This radiation which absorbs sheath, increases its temperature and heats all outside the greenhouse. Plants for heating from the surface, through the leaves, water evaporates, and if the house is closed, creating in him the water vapor. They repeatedly raise the heat in the greenhouse.
What plants need to live
If we want greenhouse plants thrived well, we need to ensure an adequate temperature, light, water and carbon dioxide.
The right temperature
At a time when the sun shines straight, the optimum temperature in the greenhouse around 25˚ and the maximum temperature should not exceed 32 ° C. At night, then the best temperature around 18 - 20 ° C. At low light intensity (if necessary cloudy), it suffices that the temperature outside the greenhouse around 20C night temperatures should not fall below 15 ° C.
How to ensure an optimal temperature in the greenhouse
Temperature fluctuations plants too assertion. The optimum temperature if it is too high, we can provide ventilation. We mechanically ventilated, by opening windows in a greenhouse, but it is convenient automatic ventilation system which allows windows to be at a certain temperature limit has opened itself through.
If the temperature in the greenhouse is too low, this problem can be solved heating, but in this case it is necessary to have a greenhouse-quality insulation to the costs of heating does not exceed the actual income from the crop. In addition, the acquisition of the greenhouse heating is not a cheap affair. There are various types of electric or propane heaters, but they are more suitable for intermittent heating. For more heated greenhouses is more suitable heat pump or
solar heating.
