A 3x8 m greenhouse for your garden

Meet the Gardener 300 The Gardener 300 is a polycarbonate greenhouse measuring 3x8 m, with a stated area of 24 m². Its 212 cm height and 800 cm length give you the key dimensions to consider when planning where it will sit and how you will arrange plants inside. The frame is made from galvanised steel, and the covering is 6 mm polycarbonate.

Details to help you plan

  1. A generous footprint: At 3x8 m, this model provides a 24 m² area for arranging crops, herbs or seedlings. Check the footprint against the space you have available before choosing a position.
  2. Galvanised steel frame: The frame is specified as galvanised steel, with 20x40 mm and 20x20 mm sections. The arches are spaced 100 cm apart.
  3. 6 mm polycarbonate covering: The greenhouse uses 6 mm polycarbonate. The listed covering comprises seven sheets, with the sheet detail noted as 6 m.
  4. Two doors and two windows: There are two doors for access and two windows. Their number and position are useful details to consider when deciding how the greenhouse will work with your garden layout.
  5. Check the dimensions: The stated length is 800 cm and the height is 212 cm. Compare these measurements, as well as the 3x8 m footprint, with your intended site before making your choice.
