Portable Greenhouse ~ What to Consider Before Buying One

Reviewed by [reviewed_by]

A portable greenhouse gives you the best of both worlds. First, it’s protected so you can grow plants in various climates. Second, you have the benefit of being able to move it around.

Before researching portable greenhouses, first you need to decide the reason you want it to be portable. Is it so you can move it frequently or once or twice a year?

Other considerations are:

  • The amount space you have
  • How many plants you want to fit inside
  • How easy it is to set up
  • Your budget
  • How long do you want it to last
  • Materials; glass will be heavier than PVC or polyethylene

A portable greenhouse needs to either be lightweight or have wheels. You don’t want to have to disassemble it every time you want to move it around.

There are generally four ways to think about portable greenhouses. These options include:

Types of portable greenhouses

  • Portable mini greenhouse
    • Smallest greenhouse
    • Can fit on a balcony
    • Usually has vertical shelves
    • Easy to lift and move
    • No wheels
  • Portable walk-in greenhouse

    • You can place it directly on top of a garden, shrubs, etc. to protect from frost
    • Easy to pick up and move it with 1 – 2 people
    • No wheels
    • Also called mini walk-in greenhouse

You may be able to find a greenhouse with wheels. However, usually these are DIY portable greenhouses.

Below we explain more about the types of portable greenhouses.

Tips before buying portable greenhouse

Something to be sure of before buying are the dimensions. Some advertisers describe the sizes in inches or feet while others do so in centimetres.

Another tip is to be sure you are buying the entire greenhouse and not just a greenhouse cover or greenhouse replacement cover.

Alternatively, be sure you are buying the entire greenhouse kit, not just the frame. You want to be sure it comes with the cover.

When you are ready to buy, you should also search the following terms which can also usually work as portable greenhouses:

  • Pop-up greenhouse
  • Plant house

Different companies describe portable greenhouses as pop-up greenhouses or as plant houses.

Portable mini greenhouse

Portable mini greenhouses

The first to consider is a portable mini greenhouse. This is a very small greenhouse you can easily move around.

Typically, there will be three or four shelves that you can put your plants or pots on. Sometimes you can adjust the height of the shelves for taller plants; however, sometimes you don’t have that option.

Mini greenhouses can range in height from 2 – 6 feet tall.

While most of them have vertical shelves, you can find some that take up more space horizontally rather than vertically.

There is usually a zippered opening and closing that you roll up and down. The greenhouse cover lining is usually made with clear polyethylene.

The frame is often made with iron tubing to provide support and to protect from rust and corrosion.

This portable greenhouse is ideal for small spaces, including decks, patios, and balconies. If you don’t have a lot of outdoor space, or if you want to set it up indoors, this is a good option.

Another reason to consider mini portable greenhouses is if you just have a few plants you want to put inside them.

It will be easy to assemble. Typically, you won’t need tools to set it up. In addition, it will be low maintenance.

The lower cost and smaller size make it ideal for beginning gardeners or first-time greenhouse owners.

You may need to weigh it down during rainstorms, on windy days, or in certain seasons.

If you don’t find the size or style you are looking for, also search for “plant house” which will pull up more options.

Cost: This is generally the least expensive greenhouse type. Price range: $25 – $70
Portable walk-in greenhouse

Portable walk-in greenhouse

Another type of portable greenhouse is one that you can walk inside. Companies will describe these as mini greenhouses, small greenhouses, or portable mini walk-in greenhouses.

They are still on the smaller side but because you can walk inside, know that they are much larger than the mini greenhouse style described above.

You can grow a wide variety of seedlings, starts, and plants inside. You may even have room on a shelf to leave gardening gloves, seeds, etc.

These are usually designed to be indoors or outdoors.

The bottom of these are unfinished, meaning there isn’t a bottom to these types of portable greenhouses. If you set it on grass, you will walk on grass. This will make it easy to stake down which is important.

If you set it on concrete, you will be standing on concrete when you are in your greenhouse. You will need a way to keep it from blowing away in strong winds.

Depending on the size of your balcony, deck, or patio, you may be able to set this up.

These small portable greenhouses are also easy to assemble. Many you can set up without tools. Most of them you snap together plastic pieces.

This type of greenhouse come with stakes to help weigh it down.

Good to use for frost protection

This is a good option to cover gardens, small trees and bushes from frost. You can simply put the greenhouse on top of it.

You should be able to get a year out of these types without having to maintain the cover. It really depends on the weather and your climate zone.

Cost: This is the second least expensive greenhouse type. Price range: $45 – $100.

Large portable greenhouse

If you are looking for a large greenhouse that’s also portable, one to consider is a portable tunnel greenhouse.

This is a greenhouse shaped like a tunnel. You can walk inside. It does not have wheels nor does it have a solid floor.

In colder months you can set this on top of your garden to protect plants from frost.

Portable tunnel greenhouses are more heavy duty than mini greenhouses and small greenhouses.

There can be one or two doors. Two doors will provide better ventilation. Some include exhaust vents. They are typically 100% waterproof.

In order to weigh it down, it comes with stakes.

This type of portable greenhouse can be 12 – 20 feet long. They can be 7 – 12 feet wide. Usually, they are 6 – 7 feet tall.

Tunnel greenhouses are fairly easy to set up though it may be helpful to have more than one person when you set up the cover. The frame is often made with heavy-duty power coated steel.

These portable greenhouses are ideal for experienced gardeners. There’s a lot you can do inside. They are easy to move around once you empty them.

In time, you may need a replacement cover because of the climate and weather conditions so factor that into the price.

Compact greenhouse

A compact greenhouse is much sturdier than the above models. You can move them but they aren’t necessarily designed to be moved often.

These can weigh 45 – 75 pounds. This means that you can relocate them on your property to take advantage of the conditions; however, it won’t be as convenient as moving the other greenhouses which are designed to be more portable.

The advantage to these types of greenhouses is that they are sturdy and compact.

Portable greenhouse on wheels

Protect plants from frost

Instead of draping frost cloths over your plants or protecting them from frost in other ways, you can enclose the plants in a greenhouse.
