How to Choose the Best Lean-to Greenhouse

There are some key features that will help you tell the difference between a high-quality lean-to greenhouse and one that would be a waste of time and money. Here are some more details about the features you should be the most concerned about when buying a lean-to greenhouse.

Cover Material

The cover material for your lean-to greenhouse Trusted Source The autumn allure of the greenhouse - The Washington Post Mark Schroeter is that way.

Polycarbonate

A polycarbonate greenhouse will provide you with better insulation than a classic greenhouse.

Polycarbonate material can be shatter-resistant, which makes it a great option if you are concerned about durability. It can effectively filter out harmful ultraviolet rays, but they are unfortunately opaque, which means you cannot see through them and enjoy the view of your plants from afar.

Plastic

Plastic lets out less heat compared to glass, as it has better heat retention properties.

Plastic film can retain plenty of heat for a greenhouse, but it may not be as durable as polycarbonate. Plastic covers tend to wear down easily, especially when they are exposed to harsh weather conditions or the sun. It may not be the most durable option, but it is often the most affordable.

Glass

Glass will, therefore, transmit the same amount of light throughout its life.

While glass may not be a material used for a greenhouse cover, there are some lean-to greenhouses that feature glass in their construction. Glass has a much better ability to retain heat, But it is also very likely to crack or break. The best thing about glass greenhouses like the MCombo Greenhouse is that it allows you to see inside clearly.

One that we highly recommend is the VivoSun Mini Lean-to Greenhouse. It features strong metal poles and a durable PE weather-resistant cover.

Temperature Control

Temperature control is one of the most important features to consider when purchasing a portable greenhouse. You want to be able to grow specific plants that rely on certain temperatures. Being able to maintain a certain temperature all throughout the year will help to ensure your plants grow properly. If there is too much humidity inside your greenhouse, you may end up killing your plants. And if you have the temperature too, they will freeze.

Ventilation

The right amount of ventilation is necessary to achieve temperature control inside your lean-to greenhouse. You do not want your plants to get too hot during the warm summer months, so finding a greenhouse with a cover that has plenty of ventilation will help to ensure your plants get the right amount of air and humidity.
