In-Depth Reviews Of Top 7 Portable Greenhouses Of 2021

Erommy 7.5FT Portable Greenhouse: Best Value For Money

This is our best portable greenhouse so far. The Erommy 7.5FT outdoor greenhouse easily outcompetes others for its ample space, high-quality materials, and affordable price.

Its price range remains comparatively affordable. Thus, it is suitable for people who are unwilling to spend hundreds of dollars on their garden.

As for dimension, this greenhouse measures 88 inches high and 77 inches wide, giving enough room for two people to be comfortably inside.

It also features three-tiered shelves, which provide you with ample space to cultivate your rainforest canopy. Basil, rosemary, radish, tomatoes, jalapenos, or peppermint; the Erommy 7.5FT has every plant covered.

A minus point of the house is the thin frame. Hence, you have to add more stakes and duct tapes for better anchoring. Otherwise, it will collapse during wet and cold weather conditions.

If anything is missing, we would say it’s a screened window to facilitate small harvesting. It can save you the hassle of getting annoying creatures clung to your clothes.

What We Like

• Affordable price
• Plenty of space
• Explicit assembling instructions
• Thick cover
• Lightweight
• Withholding humidity and heat excellently

What Can Be Improved?

• Flimsy and unstable frame
• Cannot withstand heavy rain or strong wind

EAGLE PEAK Walk-In Greenhouse: Best For Winter

If you are looking for a robust temporary greenhouse for winter, look no further. The EAGLE PEAK walk-in flower house makes itself known to customers thanks to its solid powder-coated steel frame.

With this frameset, coupled with a strong meshed plastic cover, the greenhouse can perfectly safeguard the tender plants from severe winter gales and even scorching summer.

Another plus point of this hothouse is the triangular structure in the ceiling, preventing excessive pooling from sudden downpours.

Like the Erommy greenhouse, the bottom and shelves of this one are pretty weak. As a result, it is advisable to fasten them to a fixed board/ fence or weighted bricks for better stability.

What We Like

• High-quality metal frame
• Walk-in design
• Easy to assemble
• A front roll-up door and side windows
• Strong meshed plastic cover

What Can Be Improved?

• High price
• Weak shelves and bottom parts

Erommy Portable Mini Greenhouse: Best For Limited Space

Another well-crafted hothouse from the brand Erommy made it to our list. This portable mini greenhouse can fit snugly inside a tiny corner of your garden.

Besides, the product features three flexible covers with roll-up doors. These doors are equipped with zippers and Velcro straps, allowing you to close or open them easily fully.

By doing so, you can maintain the proper humidity levels and efficiently care for the plants.

Unfortunately, this mini greenhouse cannot keep your favorite plants safe during winter. You can only use it in warmer seasons.

These Erommy portable mini greenhouses deserve every positive review they get. If you have a narrow plot and a green thumb, this pick can be an excellent choice for your plants.

What We Like

• Ideal for small gardens
• Convenient, flexible cover
• Durable covering materials
• Easy-to-follow assembly and disassembly
• Portable design allowing for much light penetration
• Lightweight yet sturdy

What Can Be Improved?

• Cannot tolerate bad weather

EAGLE PEAK Mini Garden Portable Greenhouse: Best For Extra Ventilation

Though this EAGLE PEAK flower house might strike you as small and flimsy at the first impression, it boasts a lightweight yet highly durable frame. It also comes with a thick PE cover to protect your plants from harmful UV rays and pests.

This compact greenhouse also features fully exposed windows, the openness of which can be adjusted by the zipper set. With this feature, your plants will be able to bask in the gentle, marvelous sunlight from every angle.

The overlong cover design at the bottom allows users to handily stabilize the house with stones and bricks without resorting to stakes or zip ties.

Additionally, the manufacturer offers one-year limited protection after the sale. This policy applies to the tops and frames as well.

The only quibble with this product is the fragile zipper, which can break down quickly after a short time.

What We Like

• Four roll-up zippered doors for optimal ventilation
• Highly durable frame
• Compact design
• UV protection
• Well-stitched cover

What Can Be Improved?

• Poor-quality zipper

EAGLE PEAK Mini Greenhouse With Casters Best For Mobility

This mobile greenhouse might require slightly challenging initial constructions. Other than that, it is effortless to use or move around. Thus, we strongly recommend it if your place has unpredictable weather.

We particularly like the design of this mobile greenhouse. The caster sets enable you to move the greenhouse to a safer place when there’s a heavy downpour and strong winds.

Another plus point is the large roll-up zipper door. You don’t have to lift the whole cover with this door and then put it back down only to check on your plants.

Nevertheless, like many competitors, the manufacturer still hasn’t fixed the wobbly shelves, which is slightly off-putting. Apart from it, we are pretty satisfied with other aspects of the greenhouse.

This unit is only ideal for lightweight plants such as seedlings, cacti, or succulents.

What We Like

• Highly portable
• Easy to assemble
• A large zipper door for easy monitoring
• Unique design

What Can Be Improved?

• Flimsy shelves
• Prone to falling apart

Kradl Pop-Up Greenhouse Kit – Best For Design

We specifically like the structure of this hothouse: collapsable and bottomless.

The Kradl collapsable greenhouse saves your time and effort in setting up. Pull out the handles on the side and ceiling, and everything is put together within minutes.

This greenhouse set is equipped with tie lines and poles for increased strength on the doors as well. That’s why it can weather any harsh elements, including frost and strong winds.

You will also find the bottomless design convenient enough to put directly over your garden bed or up the patio.

On the downside, the door is quite large, making it difficult for one person to fold or roll it up. Not to mention, the roll loops can be pretty short and annoying.

What We Like

• Pop-up design for quick installation
• Double as storage for gardening materials
• Spacious
• 99% waterproof
• Two side windows for better circulation
• Can be used year-round

What Can Be Improved?

• The front door is too large.
• No replacement cover

Shiyi Waterproof Mini Greenhouse Best For Convenience

We believe the minimalists and beginners will undoubtedly fall in love with this Shiyi collapsable greenhouse.

You can set up the cover almost immediately by lifting and zipping. For maximum anchor, you need to fasten the house to a robust stick or a fence.

When not in use, the cover can be folded into a small size, allowing you to keep it in a neat place for the next planting season.

This portable mini greenhouse is built with a high-quality 100% waterproof PVC cover. This will do a great job of shielding your plants from rainwater.

The only deal-breaker of this Shiyi greenhouse is that the manufacturer sells it without any stands.

You will have to buy wired shelves yourself. Thus, make sure to check the dimensions beforehand to spare the hassle of returning either of the products.

What We Like

• It can be used directly or simply by securing it with a stick
• Foldable for easy storage
• Incredibly durable
• Transparent plastic cover
• 100% waterproof
• Affordable

What Can Be Improved?

• No wired shelves

Buying Guide – How To Choose The Right Mobile Greenhouses

Portable greenhouses come in different shapes and sizes and are categorized into four major types. Additionally, you should not overlook some key aspects that constitute quality greenhouses.

Types Of Portable Greenhouses

Greenhouses can be categorized in terms of their shape, utility, construction, or covering materials. In this article, we will classify them based on the degree of portability.

Regarding this aspect, there are mainly 4 types of greenhouses, namely pop-up, walk-in, cold frame, and caster greenhouses.

Pop-up Greenhouse

This type of greenhouse lends its name to the instant, effortless set-up that can be done within minutes. A pop-up greenhouse kit typically includes ropes, posts, stakes, and a bottomless cover.

These features allow you to set up the unit simply by pulling out the handle on either wall and the ceiling. It has also proved extremely useful when you want to move it from the backyard to the patio.

Greenhouse With Caster Sets

Caster sets, or wheels, are excellent additional components to a greenhouse. They enable you to move the unit back and forth with ease whenever needed.

These sets can be made by hand. So, why not try them out? They are suitable for regions with irregular weather patterns.

Walk-In Greenhouse

As the name suggests, walk-in greenhouses are characterized by their high ceiling, often in a domed or triangular form, in which you can comfortably walk without having to duck.

Thanks to their ideal size, these units can accommodate the thriving of various large-sized plants. If you want to build a tropical ecosystem inside your house, walk-in greenhouses are the way to go.

Cold Frame Greenhouse

A cold frame greenhouse is built along with partially open windows, fixed wooden or plastic film frames, thus making it immovable. People usually adopt this kind of temporary greenhouse for maximum plant protection, especially for weather resistance.

Features To Look For When Buying A Portable Greenhouse

Materials

This is the most crucial aspect that decides how your plant batch will turn out.

Glass brings about the best light transmission among all materials, yet the set-up components are slightly costly for a typical suburban gardener. People only use glass greenhouse for highly industrial purposes.

Fiberglass is rigid, highly durable, and reasonably priced. Yet, the material tends to be broken down by UV light, making it morphed into a swollen form.

Hence, the effectiveness of light transmission decreases considerably. We suggest that you should only use fiberglass as a short-term solution.

Double sheets of polyethylene cover (PE) prove to be the most popular and economical option among producers. Though they are not as durable as their counterparts, they can provide sufficient support for daily operation.

Yet, we recommend that you should change the cover every two years for maximum results. It is advisable to consider your budget and the duration of your plants to choose an ideal material.

The Strength Of Tiers

The tiers or shelves need to be firm enough to hold the combined weight of the plants and pots. Make sure you have checked their quality carefully before making any decision.

Capabilities To Retain Heat And Humidity

Check if the greenhouse permits a large roof opening during scorching summers and if it is possible for you to use a central heating system during winters. These features will be the primary determinant of your plants’ health.
