How to choose the right greenhouse for you

There are a number of factors you’ll want to consider when deciding on a greenhouse. In this mini-series, we’ll dive into some of these important aspects.

Frame Material

Aluminum is the standard material for greenhouse frames, with minimal upkeep necessary and its svelte structure casts little shade.

Wood is an attractive choice but requires the lumber to be pressure-treated in order to hold up against the elements and its more bulky structure can cast more shade within the greenhouse.

Galvanized steel is sturdy, won’t rust and can resist winds up to 110km/hr and withstand weights up to 45kg.

Choice of Shape

The main greenhouse designs are:

Lean-to (or Wall Greenhouse) - these greenhouses are installed against a sturdy surface like a wall and they take advantage and support from an existing building structure.

Detached greenhouse -  these stand independently from one another.  The most common type of detached greenhouse for commercial production is the Quonset (also known as a “Hoop House”)  They are constructed from pipe, either PVC or metal and bent into hoops.

Gutter connected greenhouse -  is a modular structure that is composed of individual bays, which can be attached and expanded upon in order to increase growing space.

Gabled Roof Greenhouses - these use welded or bolted trusses to support the roof. These are more expensive and complex to build, but they provide the maximum amount of sunlight and offer a large area inside the structure for growing a large number of plants. 

Geodesic Dome

these offer efficient shape and structural integrity that makes them resistant to higher wind velocities, and enables them to withstand snow. They have excellent air-circulation which makes them adaptable to both hot and cold seasons.

Food for thought

It’s always important to consider your end goal when choosing a greenhouse. You want to have a greenhouse that allows for expansion and is a pleasure to use.  You'll want to consider how you’ll utilise the interior space and what you want to create. How much space is for growing? Do you want to have a work area or a place for storing tools or supplies? What other activities could you use the space for?
