Greenhouse type

Multi Span Greenhouse

A multi span greenhouse is often the right commercial answer when climate is moderate, capital is constrained or the project must prove market demand before scaling. Results depend less on buying the cheapest frame than on specifying ventilation, screening and irrigation to match the crop.

Where multi span is the commercially stronger choice

Multi span is often the stronger choice when the market will not reward premium winter quality, when the financing envelope is tight or when the owner wants to phase technical risk. In those situations, lower entry cost can create a healthier return than forcing a glass concept onto the wrong market.

Cheap frames fail when the climate package is weak

The most common multi span mistake is treating the structure as the whole project and stripping out roof ventilation, screens, irrigation control or water handling. A disciplined low-cost greenhouse with the right climate package will outperform a nominally better structure that cannot control plant stress.

  • Roof ventilation area of at least 15 - 20 %
  • Insect netting matched to local pest pressure
  • Anti-drip and anti-condensation film treatment
  • Fertigation control with drain monitoring

Strengths

  • Significantly lower capital cost per hectare
  • Good fit for phased commercial rollout
  • Fast installation and easier market-entry testing
  • Can be highly competitive in moderate climates

Considerations

  • Film replacement must be priced as a planned operating event
  • Climate stability depends heavily on ventilation and screen discipline
  • Premium winter or year-round programmes may still justify glass instead

Best suited for

  • Moderate climates and lower-capex market entry
  • Crops where premium winter quality is not the only economic driver
  • Growers prioritising staged expansion and capital efficiency

FAQ

Multi Span Greenhouse: questions from investors

What cost advantage does multi span usually hold over glass?+

Fully equipped multi span film greenhouses are often 40 to 60 percent lower in capital cost per square metre than comparable glass facilities. The real comparison must still include film replacement, crop value, winter production limits and the quality premium your market may or may not pay.

How should buyers think about greenhouse film life?+

Quality horticultural film usually lasts 4 to 6 years, depending on UV load, chemical exposure and installation quality. Serious buyers treat replacement as a planned operating event, with labour, timing and production interruption already built into the model.
