The Adley 4\' x 8\' Lean-To Wooden Greenhouse is ideal for gardeners with restricted garden space as it attaches directly to a wall, as long as the base is level and solid. Constructed from 12mm tongue and groove cladding, and a shatterproof styrene glazing that lets in plenty of light while also protecting your plants from harmful UV rays. An opening window is built into the roof allows you to regulate the inside temperature to suit needs of all plants. Please Note Our garden buildings are pre-treated with a water based timber treatment for protection during transit. In order to receive the full 10 year anti-rot guarantee, it is necessary that you treat the garden building with a high quality, spirit-based, timber preservative prior to or shortly after construction. This will protect the timber from weathering and will need to be repeated accordingly in relation to manufacturer\'s instructions. See Terms and Conditions for further information.
