How to buy the best greenhouse Greenhouse features
Step inside different makes of erected greenhouses at showrooms and garden shows to get a feel for them. The key features to consider are the amount of ventilation, how easy the frame and glazing will be to clean, the specification and the design.
Vents
You will need at least two vents in the roof and one at the side to achieve a good flow of air. The number of vents depends on the size of the greenhouse, but consider paying extra for additional ones. An automatic vent-opener is a feature well worth paying for; it contains a cylinder of wax that expands and opens in heat then closes when cooler.
User comfort
Anyone who will be using the greenhouse should make sure they can get in and out of the door easily and that the space feels comfortable once inside (low models can feel claustrophobic).
Good design
Look at how the panes of glass fit into the frame: do the panes overlap? (which makes cleaning difficult). How sturdy is the door? These are all points worth checking before you buy your greenhouse.
