At eight metres long, this Tre 300 gives you room to grow, pot up and work without feeling hemmed in. The 24-square-metre interior can hold long beds, staging and separate areas for seedlings and mature crops.
Its pressure-treated pine frame brings natural colour and texture to the plot. Strong curved ribs shape the distinctive Gothic roof.
It feels particularly at home on an allotment, at a school or in a large productive garden. The twin-wall panels are unbreakable, light and insulating. Crops receive gentler light without the safety concerns that come with glass.
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.
