Acidophils, like azaleas, rhododendrons and camellias, are the most popular cultivations in the Fondotoce valley.
Acidophils, as per their name, prefer acid soil. By walking or cycling along the paths inside the reserve in spring, and especially in May, it is possible to admire the flowers geometrically aligned as they are grown.
Anyway now most of these flowers are grown in "the artificial" atmosphere of the greenhouses, far away from your sight.
Greenhouses heating
The plants grow faster inside the greenhouses where they experience a more humid and wormer microclimate.
The higher temperature is partially obtained using "the greenhouse effects": direct sunlight crosses easily the transparent walls of the greenhouses and is absorbed from the plants. Plants use it for the photosynthesis while most of the reflected light (having a different frequency, closer to the infrared) is no more able to cross the walls back and is trapped inside, warming up the place.
The heating of the greenhouses is also obtained using standard heaters, like in your house.
The solar panels
More ecological solutions can also be applied to heat the greenhouses like incinerators (if they are "echo-compatible) and natural thermal sources or the sun, through the solar panels. A solar panel uses the solar energy to heat water moving into special tubes. This warm water is then used to warm up the buildings (the greenhouse in our case).
The company owned by Mr. Angelo Bianchi, in Fondotoce is actually using solar panels. "Using the solar panels we obtained an effective energy savings, even if the 30% reduction promised was not reached. We are now thinking about making the solar panels adjustable and remote controlled to always align them to the coming sun rays." Mr. Angelo Bianchi also has his greenhouses placed partially below the ground level to reduce heat dispersion.
