What to Consider When Choosing a Compact Greenhouse

Choosing a compact greenhouse might seem like a simple decision, but there are several considerations to weigh. The best compact greenhouses come with a durable frame that will last many growing seasons, a means of ventilation, and easy assembly. Here are some of the most important features to look for when shopping for mini greenhouse kits.


There are several different mini greenhouse styles, each of which has its advantages and benefits. Some types may work better for your garden than others. The best choice for you depends on your available space, your budget, and whether you’re looking for a permanent or portable option.

  • Walk-in greenhouses come in both permanent and portable models. They are large enough to allow gardeners to walk inside to tend to their plants. They may also have enough room to store gardening supplies.
  • Pop-up greenhouses refer to portable greenhouses that offer easy assembly, takedown, and transport.
  • Year-round mini greenhouses are small, permanent structures that stay in place all year with no need to dismantle after the growing season.
  • Tabletop greenhouses sit on a table or other flat surfaces indoors or out. They make a great choice for novice gardeners who want to transfer small quantities of seedlings outdoors in the spring after germinating them indoors.
  • Vertical mini greenhouses make a great choice for small yards or balconies because they feature shelving, which takes advantage of the available vertical space without taking up much floor space.
  • Horizontal mini greenhouses can cover plants that are planted directly in the ground or low-lying raised beds.
    Wheeled greenhouses allow you to move your plants around the available outdoor space without disassembling the structure.


The first factor to consider when shopping for a compact greenhouse is how much available space you have. Luckily, there are plenty of options available, whether your garden consists of a suburban backyard, a city patio, or a tiny balcony. Consider, too, whether you plan to bring your mini greenhouse indoors when temperatures drop to a certain level.

Generally speaking, a compact greenhouse is any model that takes up 10 square feet of floor space or less. They are typically less than 6 feet tall. Sizes vary greatly, however, with models ranging from tabletop versions that take up just a single square foot to walk-in versions more suitable for larger outdoor spaces. Be sure to measure the space you have before making a purchase.


Compact greenhouses typically come with either wooden or metal frames, each of which has both advantages and disadvantages. Consider the following factors when choosing between metal and timber.

  • Metal frames, typically made from aluminum or powder-coated steel, are low maintenance and easy to assemble. They’re generally constructed of metals that won’t rust when exposed to moisture. Many metal frames snap into place with plastic connecting pieces, which eliminates the need for tools.
  • Wooden frames, also called cold frames, provide added stability. They are ideal for year-round use in more temperate climates. They do, however, have higher maintenance requirements because they may rot over time in damp conditions. They may need periodic sanding and a new coat of stain.

Siding Material

Standard greenhouses and some high-end mini greenhouses may feature glass-paneled walls. Glass withstands harsh weather conditions and lets in direct sunlight—ideal conditions for growing seedlings. It can, however, crack or break, so some greenhouses use polycarbonate panels as a cheaper and more durable alternative. The problem with these is that they don’t let in as much light as traditional glass panels.

The most affordable mini greenhouses use plastic siding. While this makes them easier to disassemble and move, it also means that their interiors can easily overheat, which may hurt some plants. Gardeners using this style of greenhouse have to take care to avoid high temperatures and humidity levels. It’s crucial to control ventilation using roll-up windows or doors. Another downside to greenhouses with plastic siding is that they may not be able to withstand extremely high winds.

Tiers and Shelving

Larger compact greenhouses often feature tiers or shelving to allow you to maximize the vertical space within the structure. This shelving may be made of wood, plastic, or metal and generally matches the frame of the structure. While greenhouse shelving is sometimes fixed in place, some models feature adjustable shelves to accommodate plants of various sizes.

While shelving is handy for allowing you to house more plants, it’s not ideal when you’re starting seedlings. Upper shelves create too much shade and prevent seedlings on lower shelves from getting the sunlight they need.


Before choosing a mini greenhouse, consider how you intend to use it. Consider a portable option if you intend to move your mini greenhouse around your indoor or outdoor space. Lightweight metal frames and plastic siding make for the most portable options.

Mini greenhouses with wooden frames or glass-paneled walls look great and last long, but these are not your most portable options, especially the larger models.

Additional Features

While most mini greenhouses on the market feature simply a frame, cover, and shelving, some greenhouses may come with the following additional features:

  • Roll-up doors or windows: When outdoor temperatures are high, heat can build up inside the structure and reach levels that are intolerable for some plants. Roll-ups maximize airflow on hot days.
  • Indoor lighting: Found in some higher-end mini greenhouses, this feature facilitates early-morning or evening plant care.
  • Temperature/humidity control: Some units can accommodate a heater, fan, or misting system, sold separately, to help control interior climate and humidity.

The Advantages of Owning a Compact Greenhouse

Mini greenhouses allow gardeners with limited outdoor space to protect their plants from cold weather and overexposure to the sun. The best compact greenhouses serve the same purposes as standard greenhouses within the confines of a small yard, patio, or even a balcony. Standard greenhouses tend to be large and permanent, while mini greenhouses are often portable and offer easy setup, takedown, and storage.

Small greenhouses:

  • Protect plants from pests and critters;
  • Extend the growing season and let you start seedlings earlier;
  • Shelter plants from the elements;
  • Allow gardeners to create a controlled microclimate; and
  • Prevent your potting soil from erosion and overwatering by preventing precipitation from reaching your plants.


You may still have some additional questions about the best compact greenhouses. This section aims to answer some of the most frequently asked questions about mini greenhouses to help you decide if purchasing one is right for you.

Q. What is a mini greenhouse for? 

A mini greenhouse is used for protecting plants from harsh temperatures, wind, pests, and other critters. It’s a handy addition to smaller gardens or patios for extending the growing season and growing seeds, seedlings, or mature plants in cooler temperatures.

Q. What is the smallest size greenhouse?

Greenhouses vary widely in size and can have footprints of less than 1 square foot for germinating seeds in a small indoor space.

Q. Should a greenhouse be clear or opaque? 

Clear and opaque greenhouse siding provides different types of light. Clear siding gives plants access to direct sunlight, which is ideal for germinating seeds and starting seedlings. On the other hand, opaque siding provides diffuse light, which is the better choice for growing plants to maturity because it prevents hot spots.

Q. How thick does the plastic need to be for a greenhouse?

For optimal quality and durability, look for a greenhouse with a plastic cover that’s at least 6 mils (or 0.006 inches) thick.

Q. Can I put a greenhouse in the shade? 

No, you can’t put a greenhouse in the shade. Both full-size and miniature greenhouses rely on sunlight, so they should be placed in a location that receives full sun—6 to 8 hours of sunlight—throughout the day.
