The Magnum greenhouse is available in powder-coated green, black or aluminium. All come with double doors as standard, integral guttering and easy clip in glazing. This range benefits from additional height at the eaves and incorporates cast joints at both ridge and eaves together with a box-section ridge.
Ventilation is via at least two roof vents, four in the 108, 128 and 148 models. Putting up greenhouses can be a good experience especially in warm weather, and with a little bit of assistance (even just with occasional tea and biscuits). Halls greenhouses do come with good instructions.
BUT, for those who haven't got the time, or don't feel they want to do this - then Halls Greenhouse Installation can be purchased.
