Quite often, when planting seeds, it is necessary to provide greenhouse conditions for different crops. To protect seedlings from wind, cold and other external factors, use special materials for shelter. In our article we will describe lutrasil, tell you what it is and how to use it.
Description and Purpose
Lutrasil is made of polypropylene, one of the main properties of which is heat retention. In this case, excess moisture can evaporate freely. Through the use of non-woven material can accelerate the germination of seeds. Also, the canvas is protected from birds and other pests. 
Important! If you want to protect the plant from the scorching sun, choose white lutrasil, since black, although it does not transmit ultraviolet rays, will attract more heat to itself.Lutrasil has one important difference from other materials similar to it - it can be spread directly on the soil. You do not have to tinker with special designs - just sprinkle the edges with earth, so that when the wind gusts the material is not demolished.
