Meet the GARDENER 300 The GARDENER 300 is a 3 × 4 m polycarbonate greenhouse with a listed area of 12 m². It measures 400 cm in length and 212 cm in height. Its size gives you room to organise plants such as tomatoes, cucumbers, peppers, herbs and seedlings.

Details to help you plan

  2. 4 mm polycarbonate: The cover is specified as 4 mm polycarbonate. Four sheets are listed, with 6 m also noted in the sheet specification.
