A 3 × 10 m greenhouse for your garden

Meet the GARDENER 300 The GARDENER 300 is a 3 × 10 m greenhouse with a listed area of 30 m². It has a galvanised steel frame and 4 mm polycarbonate covering, with eight 6 m sheets listed as included. The greenhouse is 212 cm high. Check the footprint and height against your garden layout to see whether this model suits the space you have.

Details to help you choose

  1. A generous growing area: The 3 × 10 m dimensions and 30 m² area give you key figures for planning where the greenhouse will sit and how you might arrange plants inside.
  2. Polycarbonate covering: The covering is specified as 4 mm polycarbonate. Eight sheets, each listed as 6 m long, are included in the product specification.
  3. Galvanised steel frame: The frame is made from galvanised steel, with galvanising listed as its corrosion protection. The frame specification lists 20 × 40 mm and 20 × 20 mm measurements.
  4. Two doors and two windows: The greenhouse has two doors for access and two windows that provide openings for ventilation.
  5. Arches spaced at 100 cm: The arches are listed as 100 cm apart. This is a useful frame-layout detail to consider when comparing greenhouse designs.
