More space, wind resistant
We have created SH Magnum greenhouse to be strong enough for rough Nordic winters with loads of snow and big winds.
One of the main factors we wanted to achieve was to get more space on the sides of the greenhouse. As the result the arcs starts to bend at 1m above the foundation giving us more space at the sides so vegetables could grow higher and the efficiency of land used grows.
What we are also proud of is that plastic waste in the assembly process is kept to minimum. Polycarbonate sheets needed for covering the top of this greenhouse is exactly 6 m length.
