Polytunnel vs Greenhouse: Extend Your Growing Season Affordably

Want year-round harvests without greenhouse costs? Polytunnels—hoop frames covered in polyethylene—deliver 80% of the benefit at 30% of the price.

Why Polytunnels Win

• Winter protection: Frost/snow exclusion. Soil stays workable.
• Season extension: Plants "think" it's spring longer. Earlier starts, later finishes.
• Mediterranean microclimate: Warm, diffused light—ideal for tomatoes, peppers, exotics.
• Summer flexibility: Remove cover in heat. Greenhouses overheat; polytunnels adapt.
• Cost: Frame + poly (replace 5–7 yrs) << glass greenhouse.

Lifestyle Returns

• Year-round hobby (bonsai, orchids, specialty crops).
• Organic vegetables at production cost.
• Surplus sales = side income.

When to Choose Greenhouse

Permanent structure desired, high wind/snow loads, aesthetic priority, budget allows.

For most home growers: polytunnel first. Upgrade later if needed.
