Mini Greenhouse Sizes & Styles

Small Greenhouses for Every Space

Eagle Peak small greenhouses are designed to fit any outdoor or indoor space. From compact 4-tier mini greenhouse shelves to larger walk-in small greenhouses — our small greenhouse collection offers the right solution for gardeners with limited space who want maximum growing capacity. Available in multiple sizes to fit patios, balconies, decks, and small backyard gardens.

Choosing a Mini Greenhouse

Match the greenhouse to the job. For seed starting and herbs, a 2-tier or 4-tier shelf unit is usually enough. For overwintering potted plants, choose a taller unit with room for pots at full height. For year-round growing with room to move around, step up to a walk-in model. If you plan to relocate it seasonally, prioritize lighter frames and tool-free assembly.

Mini Greenhouse FAQs

Common questions about choosing and using a mini greenhouse.

What is a mini greenhouse?

A mini greenhouse is a compact, enclosed growing structure — usually under 8 feet wide — that traps heat and humidity to protect plants. Most use a steel frame with a clear or translucent cover. They range from small tiered shelf units for balconies to walk-in models for backyard gardens.

How small is a mini greenhouse?

Mini greenhouses typically range from about 19 by 27 inches for a single-tier shelf unit up to roughly 6 by 8 feet for a compact walk-in. Tiered shelf models are the smallest, occupying under four square feet of floor space while offering three or four growing levels.

Do mini greenhouses actually work in winter?

Yes. A mini greenhouse typically holds temperatures 5 to 15 degrees Fahrenheit above the outside air on a sunny day, which is enough to overwinter hardy plants and protect against frost. For sustained freezing temperatures, add a greenhouse heater or heat mat and insulate the base.

Where should I put a mini greenhouse?

Place a mini greenhouse where it gets six or more hours of direct sun, ideally facing south or southeast. Choose level ground, and site it against a wall or fence for wind protection. Anchor it with stakes or weights — small greenhouses are light and can tip in gusts.

How do you keep a mini greenhouse from overheating?

Open the roll-up door or ventilation windows on warm days. A closed mini greenhouse can exceed 100 degrees Fahrenheit in direct summer sun. Vent it every morning, add shade cloth during peak summer, and use a thermometer inside so you can see conditions before plants are stressed.

What is the difference between a mini greenhouse and a cold frame?

A mini greenhouse is a taller enclosed structure you access through a door or panel, with room for shelving and upright plants. A cold frame is a low box with a hinged transparent lid, sitting close to the ground. Cold frames suit seedlings and low crops; mini greenhouses handle taller plants.

How long does a mini greenhouse cover last?

A quality PE or PVC mini greenhouse cover lasts about two to four seasons with regular outdoor use, depending on sun exposure and climate. UV-treated covers last longer. Storing the greenhouse over winter, or removing the cover during severe weather, extends its life considerably. Replacement covers are available.

Can you use a mini greenhouse indoors?

Yes. Tiered mini greenhouses work well indoors for seed starting and propagation, typically paired with a grow light since indoor sunlight is rarely sufficient. They hold humidity around seedlings and keep growing supplies contained. Ensure the unit sits on a waterproof surface or tray to catch drainage.

"Your guys Print [custom print] is literally probably the best I've ever used. High quality, like the best everything, from the stitching, from the way you guys sewed it, from even the zippers, like I've done a lot of Print and I'm telling you that's good. And even the Top, man it fits tight and perfect, it's really nice. Thank you."

I already own to supposedly easy up canopies that I absolutely cannot put up by myself and my husband and I struggle to put it up. I was in search of something that would actually work for me when I was by myself and I wanted to have some instant shade. I definitely had my doubts about this product. But after I received my canopy and was able to fully expand and set up the frame and just a few minutes by myself I was more than happy. Now I have to save up to get a second one. Also I needed to call customer service and I have to say they're extremely responsive and easy to deal with I recommend dealing with Eagle Peak 100%!!

We needed something quick and easy to setup for some seed starts while we plan for a more permanent structure. Researched options and found this to be perfect for our immediate needs. So far it has done the job perfectly. We have it lowered and added buckets around the base to deal with the heavy spring wind gusts. It's still up and shows no sign of tearing, bending or breaking. Thank you.
