Greenhouses vs Polytunnels — Which Should You Choose?

An honest comparison of Greenhouses and Polytunnels for Irish gardeners.

Product Overview

Greenhouses

Greenhouses provide a controlled growing environment with glass or polycarbonate panels on a rigid aluminium or timber frame. They offer maximum light transmission, excellent temperature retention and a permanent, attractive garden structure. Greenhouses allow year-round growing in Ireland, extending the season by months and enabling cultivation of tender crops like tomatoes, peppers and aubergines that struggle outdoors in the Irish climate.

For Irish gardeners, greenhouses offer particular advantages given our maritime climate with mild winters, moderate summers and regular rainfall. The availability of quality products from Irish retailers like MCDS.ie means you can choose from a wide range of options with expert advice and reliable delivery.

Polytunnels

Polytunnels use polyethylene sheeting over a galvanised steel frame to create an affordable protected growing space. They offer more growing area per euro than greenhouses, with walk-in designs providing ample headroom and working space. Polytunnels are particularly popular with Irish growers for vegetable production, as their large floor area allows crop rotation and companion planting on a scale that greenhouses cannot match.

In Ireland, polytunnels are readily available from garden centres, hardware stores and online retailers including MCDS.ie. With the right product choice and proper setup, they can perform excellently in Irish gardens throughout the year.
