The longest Vegg 300 creates an impressive 18-square-metre greenhouse along an existing wall. There is space for generous beds, organised crop zones and comfortable working room throughout the season.

Swedish pine and curved timber ribs give this greenhouse its unmistakable character. The structure is built for demanding Nordic weather.

This model is well suited to schools, community gardens and ambitious growers with a long wall available. The unbreakable glazing is a practical advantage on active or exposed sites. Twin-wall panels spread the light and hold an insulating air layer.

It is supplied without a back wall and must be fixed to a sound, suitable structure. Once fitted, the wall helps shelter the growing space and can hold useful daytime warmth.

  • 6000mm (19ft 8") Long - 18 square metres of sheltered growing space.
  • Impregnated Swedish Pine - Warm natural character with pressure-treated protection.
  • Solid Curved Gothic Arches - A distinctive structure built for demanding weather.
  • 6mm Twin-Wall Polycarbonate - Unbreakable panels diffuse light and help retain warmth.
