Both the poles, the glass roof and the plants suffer from the pressure when there is snow on the greenhouse.
Snow is very heavy and for this reason alone the construction of a greenhouse is subject to a great deal of pressure from the snow on it. Both the poles and the glass roof groan under the high pressure from the snow, so you should snow on the greenhouse better remove.
Light is reduced by snow
But removing the snow is also very important for the plants. The incidence of light is very short in winter and the sun is significantly less powerful. If the incidence of light, which mainly comes through the roof, is now also reduced by the snow, the exposure of the plants in the greenhouse is reduced even further.
Rule of thumb:
The rule of thumb is that whenever the power of the sun fails to melt the snow on the greenhouse roof, it is important to clear the roof is.
In addition to clearing snow, soot and dust particles are also removed from the roof of the greenhouse, which can also reduce the incidence of light. While snow is welcome on outdoor beds because it protects crops from intense winter frost damage, on the greenhouse roof it is detrimental to both the plants and the greenhouse itself.
