Multi-span polyethylene greenhouse
What is a multi-span polyethylene greenhouse?
A multi-span polyethylene greenhouse joins arched, film-covered bays along shared gutters into one connected growing area. It costs less per square metre than glass and suits vegetables, berries and nurseries, but the film needs replacing on a cycle and ventilation decides performance.
