The Vulcan are a good choice for growers who want a megastrength, permanent, hassle-free structure. Unlike old fashioned Greenhouses, the Vulcan’s have Superstrength with big legs that are drilled into the ground, avoiding expensive bulky concrete foundations.
The new age Vulcan’s can withstand storms, built with ‘muscular’ steel legs, hoops & strutting.
Osprey’s commercial farm built a similar Vulcan structure with tabletops in 1991 before any known polytunnel in existence.
