If you don’t have a lot of yard space or want a smaller version of a traditional greenhouse, portable greenhouses are the perfect solution. Also called miniature greenhouses, they’re perfect for gardeners who want to grow plants in a safe, controlled environment.
There are several types of portable greenhouses, ranging in size, materials and shelving options available. You can narrow down your choices based on the plants you want to grow and how much room you have.
Portable greenhouses have the following benefits:
Portable greenhouses are usually more lightweight and portable than traditional models. This means you can easily move them around on your property if needed. If you have a small enough one, you can also take it with you if you relocate.
Where you install the portable greenhouse depends on its size, shape and how much sun your plants may need. Common areas include a balcony, patio, yard or garden.
There are several types of portable greenhouses.
Most greenhouses have metal frames, such as aluminum or steel. Some use wood, but this is less common. Greenhouses have covers to protect plants, which are usually made out of polyvinyl chloride, plastic, polycarbonate or glass.
Most covers, such as polycarbonate ones, provide extra ultraviolet protection to plants. They also provide optimal protection for plants and make it easier to grow them.
Most greenhouses are square or rectangular. Some have a base, while others go directly onto a concrete, wood or dirt surface.
Many vertical greenhouses have multiple shelves, some of which you can adjust and remove as needed. This feature makes it easy to grow different types and sizes of plants at once.
Another common design feature is doors. Some open from the top, while others open from the side. A few use a zipper and a flap instead of a solid door.
Portable greenhouses are usually under 6 feet tall. Many are even smaller and more compact. Generally, vertical models are taller and narrower, while horizontal ones are the opposite. Depending on the size and construction material, most weigh between 10 to 80 pounds.
If you’re new to gardening or want to grow a few plants, start with a smaller greenhouse. But if you’re an avid gardener or are interested in growing a lot of produce, choose a larger one.
