In-depth 7 Top Rated Portable Greenhouse Reviews

1. Quictent 20’x10’x6.6’ Heavy-duty Portable Large – Best portable greenhouse for winter

Check Latest Price

If you are looking for a large portable greenhouse, this walk-in item from Quictent is an ideal choice for you.  With 20 x 10 x 6.6 feet, this greenhouse is suitable for growing big plants like monstera plants or snake plants.

This item is portable yet sturdy. It is designed to withstand harsh winter elements. The main framework is steel with powder coating and strengthened with three-corner and four-corner joints for effortless installation. Together with 10 bases and 20 stakes, these joints also help protect your plants in hard snowstorms and strong winds.

Proper ventilation plays a critical role in a greenhouse’s function. This Quictent house features two side double-layered doors with independent zippers.

The reinforced mesh door acts as a passive ventilation system, keeping the inside environment well-ventilated all the time. It also lets 85% of natural sunlight through while protecting your plants from getting burned by ultraviolet rays. Besides, it also helps avoid the intrusion of small animals, insects, and bugs.

The outer PE layer keeps your plants warm and extends their growing season, even when winter comes. Apart from the two main roll-up doors, there are 10 vents alongside the tent, giving you more freedom in maintaining a perfect environment for your lush indoor garden.

Pros Cons
  • Two heavy-duty double-layered doors with 100% waterproof
  • Strong powder-coated steel frame with joints, stakes, and bases for added stability
  • Easy installation
  • Need to secure the cover with rocks and pieces of wood on strong winds
  • No tear-resistant warranty

2. Quictent Upgraded 25’x10’x7’ Portable Large – Best portable greenhouse for vegetables

Check Latest Price

This 25x10x7ft greenhouse is similar to the above walk-in Quictent item. It also comes with a reinforced PE cover, steel framework, and two zipper doors.  However, it has some upgrades compared to the first one.

First, the main framework of this greenhouse is made of galvanized steel with better corrosion resistance when exposed to moisture than with the first one with a steel framework.

Second, this portable greenhouse features 3 rows of crossbars on the roof, while other items like Quictent 20x10x6.6 have only one crossbar. This round steel frame prevents the accumulation of snow, ice, and rainwater, thus extending the PE cover’s lifetime.

The U-shaped stakes grip the tent firmly on the ground, minimizing the damages on your freshly-grown veggies and flowers inside. This kit comes with extra accessories of 5 ropes, and 24 stakes to enhance the greenhouse’s stability.

The awesomeness of this Quictent greenhouse is also demonstrated in its every detail. There are free screw covers and 2 pole covers to prevent these minor parts from rusting or scratching. You can install these covers easily with the two pairs of gloves (free provided in the product package).

Besides, the manufacturer also offers lifetime replacement on these connectors.

Apart from its advantages, there are drawbacks to this portable greenhouse. Many people say that this greenhouse is still blown away when a strong wind comes. So, you should secure it priorly with wood or bags of sand at the bottom.

Furthermore, it weighs 90.4 pounds, much heavier than the first Quictent greenhouse (only 26 pounds).

Pros Cons
  • Galvanized steel framework with better corrosion-resistance
  • Two zipped doors and 12 exhausted vents for maximum ventilation
  • 3 rows of crossbars for better snow and water
  • Free screw covers and 2 pole covers
  • Much heavier than the first Quictent greenhouse

3. EAGLE PEAK 6’x4′ Portable Walk-in Greenhouse – Best Small portable greenhouse

Check Latest Price

This Eagle Peak pop-up greenhouse boasts a compact 6 x 4 feet size, making it a perfect pick for indoor or outdoor garden setup. It promises to deliver a hassle-free assembly, takedown, and transportation.

You can install this portable greenhouse without the help of anyone else or special tools, thanks to its one-person setup technology. While the frame of other counterparts comes in multiple pieces, its canopy frame is ready straight out of the box.

Just open the canopy frame, attach the top, and adjust the tent’s height for your perfect coverage. When not in use, you can glide to close it and store it in a small corner of your home garage.

Small as it might seem, this mini garden offers comfortable access to take care of your plants daily. You can also install a shelving system to make the most of your greenhouse’s space.

Besides, you can modify its 3-part adjustable leg system for more extra headroom. The steel legs are sturdier than others because each leg’s tube is larger than other brands.

But what I love most in this small tent is that it has doors for optimal airflow just like any full-sized ones, including one zippered door, two roll-up windows, and mesh-reinforced fabric walls.

Although the manufacturer said that you could put this greenhouse in your backyard, I’m afraid that it isn’t supportive enough to withstand harsh weather conditions, like strong winds, brutal snowfalls, or long UV exposure in summer.

Pros Cons
  • Can be used indoors or outdoors
  • One-person setup technology
  • Adjustable steel leg with 3 height levels
  • 1-year warranty for frame and roof
  • Hard to use outdoor on strong winds and brutal snowfalls

4. Gardman R687 4-Tier Mini Greenhouse – Best portable greenhouse for succulents

Check Latest Price

If you are keen on gardening but space is a matter to you, you can try the Gardman R687. This mini greenhouse is only 27” long x 18” wide x 63” high, making it ideal for growing small tropical plants like succulents.

Since this 4-shelf portable greenhouse is lightweight with a weight of 11.2 pounds, you can install it next to your home wall, patio, balcony, or in any empty corner in your property without taking much space. It has 4 tiers to maximize your outdoor gardening space.

Watering or taking care of your plants is easy as pie since there is a roll-up zippered door for easy access. You can use this door to control the humidity inside to keep your plants thriving.

The removable clear polyethylene cover allows natural sunlight to enter while protecting your young plants from hard rains or light snowfalls.

Pros Cons
  • Compact and lightweight
  • Ready-use shelving system with 4 tiers
  • Affordable
  • Not advisable to use as a permanent outdoor greenhouse
  • The roof is not designed for water and snow accumulation

5. Worth Garden 5 Tier Mini Portable Greenhouse – Long warranty

Check Latest Price

This mini portable greenhouse is similar to the above Gardman one but has 5 tiers for extra gardening space. Each tier has a maximum weight capacity of 23.4 pounds.

This Worth Garden greenhouse is manufactured of durable, rust-resistant material. The frame is made of stainless steel, which is strong enough to hold the growth of your seed trays, pots, and plants. This frame is shielded with a 0.12mm PVC protection cover. This cover is marked as ‘cold-proof,’ meaning it can keep your plants from being frozen or damaged.

Another unbeatable advantage of this portable greenhouse and other gardening products of Worth Garden is that it comes with a 3-year warranty. Thus, you can call or email Worth Garden’s support team whenever a problem arises. I rarely see this extended warranty in most of the expensive full-sized greenhouses on the market.

Pros Cons
  • 5 tiers for growing various types of plants
  • Rust-resistant steel frame
  • 0.12mm cold-proof PVC cover
  • Not for heavy-duty use or heavy planters
  • No available walk-in

6. Homewell Walk-in Greenhouse 3 Tiers 6 Shelves – Good value for money

Check Latest Price

After getting started with gardening for a few months, your plants grow taller and bigger, and it’s time to move them to a larger house to catch more sunlight. This greenhouse from Homewell is an excellent upgrade option for you.

This portable greenhouse offers 6 wired shelves with 75 pounds of weight capacity per shelf (meaning one more shelf compared to the above Worth Garden item) for storing all of your plants.

It is also spacious with the dimensions of 56 x 29 x 77 inches and has a small walk-in so that you can have comfortable movement inside. You can use this new house to grow big flower beds, vegetable beds, or take care of them daily with ease.

Pros Cons
  • 6 shelves with a maximum weight capacity of 75 pounds/shelf
  • Walk-in available
  • Not durable

7. Quictent Waterproof UV Protected Mini Cloche Greenhouse – Best for seed bed

Check Latest Price

This outdoor portable greenhouse from Quictent is designed for seedbeds or plants that are hard to be moved. You can continue growing all your plants without letting go of several ones.

While this mini greenhouse is much smaller than other conventional greenhouses, it still offers essential functions for the steadily healthy growth of your plants inside.

The powder-coated steel framework, along with the transparent PVC cover, protects your newly-grown plants. Besides, you can keep the inside environment well-ventilated or water your plants efficiently, thanks to the zippered doors. You can keep the side doors always open with either external or internal straps.

On hot summer days, you can open all doors for maximum airflow. Still, I prefer the two-layered door option with reinforced mesh and PE cover. This door type can help me maintain ideal ventilation for my plants while protecting them from uninvited guests like bugs, insects, pets, wild animals.

Pros Cons
  • Suitable for plants that can’t be moved
  • Doors with zippers and straps for easy access
  • Not as flexible as the two-layered PE cover

My Top Pick

To pick up an appropriate portable greenhouse, you should consider your available space, whether you want to start seeds in spring or do it all year round, and whether to keep it permanently or take it down before winter.

If you ask for my recommendation for the best portable greenhouse for home use, the first Quictent Large Walk-in is always my top choice. This item has sturdy construction to keep your plants growing happily and healthily inside. Although it is relatively pricey for starters, you can buy it once and use it for years with no big worries.
