As long-term practice shows, effectively it is possible to grow up plants not only in natural, but also in hothouse and even room conditions. However it is possible only if lighting is organized at the appropriate level.
Now exclusively LED lamps are for this purpose used. It is caused by the fact that these lamps have a number of unique characteristics.
It is worth paying special attention to the fact that not any light is useful to plants. Moreover, quite narrow range which is as close as possible to natural sunlight is favorable. For this reason LEDs which are used at cultivation of plants possess quite narrow range of radiation.
From here one more very important advantage follows. As infrared and ultra-violet radiation is minimized or completely is absent, such lamps practically do not influence temperature conditions indoors. Therefore they are absolutely safe for all plant species.
LEDs are favorable also from the economic point of view. It is caused by several factors at once. First, they possess the maximum life cycle. No failures in their work during this time can be. Therefore need to replace qualitatively executed device arises extremely seldom. Secondly, they consume the minimum quantity of the electric power. In comparison with normal lamps, they are seventy percent more economic. Thus, accounts for electricity will decrease practically by two thirds, and the performance level will remain the same.
Similar qualities are especially relevant in the conditions of climate of the CIS countries. Natural lighting in the necessary quantity cannot almost be received, and electric power cost quite high.
One more very important factor is placement of lamps. It is very important that they have been located under the correct corner. Everything needs to be calculated so that light fell mainly perpendicularly concerning leaves of plants. Of course, radiation will be absorbed by plant anyway, but there will be it much less effectively. Therefore, that LED lamps performed the function most effectively, they should be placed horizontally. Though any other situation will be also acceptable both for design, and for plant.
