Which greenhouse to buy
There are many options to consider for first-time buyers
YOU want a greenhouse, but which model would suit you best? There are so many options out there, it’s hard to know where to start.
The first thing to say is go for as large a structure as you can afford or fit in your garden – and remember that even then it will never seem big enough!
Look at your budget and consider what frame you want. Aluminium, either natural or painted, is a traditionally popular option and is light, easy to fit and casts little shade.
Wood is attractively ‘rustic’, but needs more upkeep, takes up valuable glass space and is more expensive.
When it comes to glazing materials, glass is the best as it lets in 90% of available light, reflects heat and doesn’t lessen the quality of the sunlight. Toughened glass is a must for doors and where there are children and pets.
Polycarbonate sheeting is lighter than glass and more durable, being less likely to break. However, it lets less pure light through, which can slightly limit seedling growth. We have replaced a couple of
broken glass panes with this material, but they are low down and have had no effect on optimum growing. Choose a sunny site
away from large trees, hedges or buildings. Position your greenhouse on an east-west axis to maximise the plants’ exposure to sunlight, even in winter. Shelter it from northerly and easterly winds, which chill the air and can knock back young plants and seedlings.
Angle your greenhouse on an east-west axis and site it somewhere relatively sheltered
