This is the largest Tre 300, giving serious growers 36 square metres beneath its sweeping timber arches. Its long interior can support several crop zones, generous staging and enough working room for supervised groups.
Swedish pine and curved timber ribs give this greenhouse its unmistakable character. The structure is built for demanding Nordic weather.
It is ideal for schools, community gardens, allotment groups and anyone planning a large protected growing space. The unbreakable glazing is a practical advantage on active or exposed sites. Twin-wall panels spread the light and hold an insulating air layer.
The opening rear window works with the door to move fresh air through the greenhouse. Optional roof vents and automatic openers make summer temperature control even easier.
