A comment
I successfully operate the Botanik-Premium greenhouse with seven transverse films and all-welded ends, providing a high degree of design reliability in any conditions. I like the presence of 2 window leaves and a pair of doors, allowing for the ventilation of the greenhouse.
Convenient arched form goes well with the general style of the design of the suburban area. Last season allowed us to collect two full-fledged strawberry crops, which, thanks to their large size, can be grown almost on an industrial scale. Solid-bent and fully-welded arches guarantee the greenhouse's resistance to negative weather factors.
pros
Reliable strong design, good productivity, ease of use.
Minuses
High cost, requires a lot of space on the site, insufficient protection from ultraviolet radiation.
