Choosing the best mini greenhouse
Best places to buy mini greenhouses
How much space do you have?
While investing in a mini greenhouse will make gardening easier and more enjoyable, you'll want to make sure that it doesn't take up all of your available space. Growing lots of plants is all well and good, but when the sun comes out you'll still want to have enough room on your patio to soak up the rays and invite your friends over too. If space is really at a premium, consider a portable mini greenhouse that you can move around your garden to where it's needed most.
How windy is your outside space?
While cheaper plastic mini greenhouses are a great budget buy, they're not the most stable in windy conditions, so may need securing properly if they're on an exposed balcony.
When will you use your greenhouse?
Is your mini greenhouse solely to keep your plants protected throughout the winter months, or will you use it all year round for cultivating seedlings too? If your greenhouse will be in use all all year, a more solid wooden design will be worth the investment.
