Wood vs metal frames
Wooden-framed mini greenhouses tend to be more attractive and easier to assemble than metal-framed ones, but cost considerably more for the same amount of growing space – especially if made from rot-resistant oak or Western red cedar.
Glass vs polycarbonate
Horticultural glass is cheapest, but toughened glass or polycarbonate is a must if there are children around. Toughened glass and polycarbonate cost about the same, but the former looks more attractive and is more durable.
Portable vs fixed
If you don’t intend to use your mini greenhouse all year round, you may prefer one that can be moved out of the way easily when not in use.
Sometimes shelves are an optional extra, allowing you to tailor your mini greenhouse to suit your needs. Shelves that are easily removable to accommodate taller plants are best.
With some larger glass mini greenhouses, there’s the option of buying a metal base-frame to stand it on. It makes assembly easier and the frame more rigid – especially when standing it on soil rather than a hard surface.
The larger glass mini greenhouses especially are often discounted in price, so it pays to shop around.
Ideally, a mini greenhouse should face east or west. South-facing ones overheat in spring or summer unless shaded, and north-facing ones suit only shade-loving plants. All need a firm, level surface to stand on. Fixing it to a wall rather than a fence will provide more frost protection, as walls absorb more of the sun’s warmth.
