What are your favorite plant's bright spots?
First of all,, at the discretion of the Usambara mountains, basically there is no seasonal difference in the length of the day - all year round light is present in 12 to 13 hours during the day.
For fans of Parma violets in temperate zone, This suggests that in the last days of fall and winter, African violets will be illuminated, artificially increasing day length to 12 hours, and in summer duration noptii.
Second, African violets grow under trees and are part of plants that tolerate shade. Optimal illumination for these plants is luxurious 1000-1200. In reality, light levels vary from one variety to another African violet.
There is a general rule in terms of lighting: Violets dark leafy need more sunlight, The light leaves, mai gingase, wavy, fluffy and leafy prefer shady places.
The place where plants usually sit sill, a place where lighting conditions vary depending on the season,weather outside, positioning window. We recommend sills located to the east or west, and sunlight should fall evenly on the surface of plant.
Ilumnarea on the windowsill is approximately 1200 lux (40% light off), but this value varies, at 5000 lux in sunny days in summer to 250 lux in gloomy winter day. In order to provide optimum conditions for development violets, stick plantele if vor umbri, and winter plants will further illuminate.
At the same, African violets grown on windowsill, will rotate constantly in order to avoid asymmetry of the knob. Violets grown on specially designed shelves with lighting above do not face such problems.
Appearance Saintpauliei plantations can determine if the lighting conditions in the room agreed:
Exces of lumina: The leaves are thick, se ingalbenesc, becoming even brown, Leaf stalks are short, rosette sticks to pot, Firstly if they embrace pot leaf. Rosette center thickens, flowers are tucked between the leaves and can not get out from under these. The flowers are small, dwarfed, paler colored, wither quickly. Look like they hide under leaves bright sunlight.
In this case, plants need shade. You can use gauze, muslin, percentage substance. Some florists paint the bottom of the window with lime. If paper is used for shading, tinfoil, these materials will stick on the opposite side of the glass, as the air around them, in sultry, strong heat and cause burns to the leaves.
Deficit Light: Pick up leaves, are pale, subtiri si gingase. Leaf stems elongate. Flowering plant stops. In this case the plant needs additional lighting.
The changes undergone by the plant because of wrong are irreversible lighting;: even if the plant will be moved to another place where lighting conditions are favorable the plant, a normal and a correct form would have only the new-emerging leaves.
Of Course, African violets grow, flourish and multiply on the window sills without artificial illumination throughout the year. But if we are dealing with a pretty golden collection, window sills are becoming more crowded and then artificial illumination solution dvine.
