What to Consider When Purchasing a Portable Greenhouse

Size of Area and Greenhouse‌: To select the perfect sized portable greenhouse, measure the area where you plan on using it. You don't want to open up your new greenhouse only to find it's too big to fit in the chosen location or a larger one would have fit. Take into account the vertical and horizontal dimensions of the area.

Material and Construction‌: For long-lasting use, select a greenhouse having a durable and sturdy structure that won't collapse with the slightest movement or amount of use. Rust-resistant metal structures withstand more than one or two growing seasons and can last for years. Make sure the pieces join together sturdily and don't wobble around because they are flimsy. Additionally, durable cover materials that withstand various outdoor conditions while protecting your plants are imperative.

Ventilation‌: Ventilation in the portable greenhouse allows you to control the amounts of heat, air and humidity created in its inside. During summer, when temperatures are hot, you should be able to open the ventilation area which allows more cooling airflow inside. In winter, closing everything up creates more heat inside the greenhouse keeping your plants warmer.

Plants and Shelves‌: To select a large enough greenhouse, consider the size of your plants and how many you have. In addition, if you're growing potted plants like veggies and flowers, or you'll have seed-starting trays, you'll probably want a greenhouse with shelves. Shelves make tending your plants easier as they're off the ground, and you can have more plants in your greenhouse because there's more space.
