The best new mini glasshouses
Nine of our new favourites. Now you can grow under glass in the smallest of spaces.
A glasshouse is an essential for the serious propagating of flowers and plants, keeping your seedlings warm and safe, protecting them from the elements and making all kinds of growth possible in the chilly UK climate.
As well as protecting delicate leaves and early growth from wind and rain a glasshouse warms plants by trapping air inside which is heated by the suns rays passing through the glass. The result is that through spring and summer the interior of a greenhouse is far warmer than outside, convincing plants that they are in far sunnier and warmer climes.
Meanwhile in winter it's possible to continue the illusion though the use of a simple electric or oil or gas fuelled heater, keeping the chill off whatever you grow inside.
The only downsides to ownership therefore are the cost to build and the size of plot required to provide a home for one. However, mini greenhouses have no such drawbacks. They come in huge range of designs and sizes, and there's an option to suit every budget. And if you're just starting out and don't need a full-size glasshouse, they're a great way to get started with growing!
