8 Small Plastic Greenhouses For Space Limited Gardens

Small plastic greenhouses are a great way to extend your gardening season and they are steadily increasing in popularity due to their flexibility and portability. These small plastic greenhouses make it possible for you to start seeds earlier and clone plants from cuttings with greater ease, all while using less space than traditional larger aluminium and or wooden structures.

With many gardeners turning to and looking for alternative methods, small plastic greenhouses are both mobile and a popular choice for those who have limited space in their gardens.

Small plastic greenhouses allow the gardener more freedom and flexibility in their gardens and or allotments, as well as being easier on plants themselves since they don’t require quite so much room or resources to ‘condition’ inside if needs be.

Are Small Plastic Greenhouses Any Good?

Small plastic greenhouses are a good alternative to the traditional, full-sized glass type. They vary in size and shape but typically come with less than 10-12 sq ft (0.9m2 – 1.11m2) of flooring space for growing seedlings early on, or even needing high humidity levels when growing indoors during cold days/nights; they’re particularly popular amongst gardeners who only have limited outdoor space at their disposal!

One of the best things about small plastic greenhouses is that they are easy to make if you want to. Gardeners often construct their own, just by building something out of wire and fitting it with a cover made from plastic sheeting! However, if you would rather purchase one – don’t worry; they’re not too expensive when compared with larger-sized models and this post will give you some suggestions for small plastic greenhouses that may suit your needs.

VegTrug – Small Plastic Greenhouse

This 4-tier mini greenhouse from VegTrug is a great addition to your home or garden.

With its FSC timber (cedarwood) frame, adjustable shelves, and re-enforced (PE) polyethene plastic cover, it will be the perfect place to grow your favourite flowers and vegetables, ideal for starting off seedlings as well.

Suitable for any garden, the Vegtrug mini greenhouse measures 20in – 49cm (D) x 31in – 79cm (W) x 62in – 158cm (H). Like many of these small plastic greenhouses, the Vegtrug takes up little room in your garden or backyard.

We also liked the solid wood frame, which helps with greenhouse stability in windy conditions.

Unlike most mini-greenhouses where users have fixed height shelving, this Vegtrug model provides the user with the flexibility of ‘adjustable wooden slats’ which allows for ‘taller plants’ and or ‘growing plants’ to be catered for based on user requirements.

There are 16 loose slats in all, but they are all movable so you can arrange them wherever you like on any of the shelves.

VegTrug WGH401N Natural Wooden Greenhouse

Covered in a strong and sturdy clear quality polythene plastic cover, with equally strong zips that allow for easy access to your plants. The option to ‘roll up’ and ‘secure’ the front opening, for ventilation purposes, is easily undertaken. The ‘Vegtrug small plastic greenhouse allows plenty of light but helps protect your delicate plants from the harshness of the UK winters.

Easily put together, the wooden frame is treated with a water-based preservative that is food safe, but the manufacturer recommends and requires that the wooden frame be treated again annually, which is a slight drawback. 

A great compatible add-on for this mini greenhouse unit is the VegTrug side table, which folds away for easy storage, and is ideal for ‘potting on’ work with no bending over required as it has a great comfortable working height.

One last tip, if you are not going to move the greenhouse, we suggest that the wooden frame is fixed to a solid structure like a wall, to provide an even more sturdy fixture.

CHRISTOW Walk In Mini Plastic Greenhouse

The CHRISTOW Walk In Greenhouse With Shelves is a versatile and affordable solution for UK gardeners looking to propagate seeds and grow plants in limited spaces.

Available in two main variants; Large-(4 shelves) and Extra Large (8 shelves)-this greenhouse features a rust-resistant steel frame, a reinforced polyethylene (PE) cover, and a roll-up zippered door.

Designed for patios, courtyards, and small gardens, it provides ample space for seedlings, vegetables, and flowers while offering easy assembly and wind resistance.

Below, we explore its key features based on our research, customer feedback and insights from Christow’s official site and other online sources.

Ogrow Mini Plastic Greenhouses

Key Features

Reinforced PE Cover

The greenhouse’s cover is made of a triple-layer polyethylene with an internal grid, offering greater durability and insulation compared to standard PVC. It’s UV-resistant to reduce fading and allows sufficient sunlight for plant growth, though some users note it can feel slightly opaque, potentially reducing light intensity.

Rust-Resistant Steel Frame

The frame consists of powder-coated tubular steel poles with plastic connectors, designed for easy click-together assembly. Many customers praise its sturdiness when properly secured, though it’s lightweight and requires anchoring in windy conditions.

Adjustable Shelving

Available with either 4 or 8 mesh shelves (depending on the model), the greenhouse offers flexibility for different plant heights. Shelves are removable, with 16in (40 cm) spacing.

Because they have a mesh design, they allow your plants to easily drain when watered. There’s also space beneath the bottom shelves to store bags of compost and other essentials.

Roll-Up Zippered Door

The double-zippered door rolls up and secures with ties, improving ventilation and access. While most users find the zips robust, a few did mention issues with zippers catching or breaking.

Wind-Resistance Features

Equipped with guylines, U-clips, and pegs, the greenhouse can be secured to the ground. Many customers recommend additional anchoring (e.g., concrete slabs or heavy compost bags) to withstand strong UK winds, as the lightweight design can act like a “kite” in storms.

Warranty

Christow offers a standard 6-month warranty on this greenhouse, covering manufacturing defects. However, it’s worth clarifying terms with the retailer before purchase if this is of concern.

Additional Information

The CHRISTOW Walk In Greenhouse comes in two sizes: Large 6ft 4in x 4ft 7in x 2ft 4in (195 cm x 143 cm x 73 cm) H x W X D – 4 shelves and Extra Large 6ft 4in x 4ft 7in x 4ft 7in (195 cm x 143 cm x 143 cm, H x W x D – 8 shelves). Both feature a green-tinted PE cover with a white checkered pattern, which some users note reduces light transmission compared to clear covers.

Assembly requires no tools, and clear instructions are included, though some customers recommend labelling poles for easier setup. The product is ideal for growing tomatoes, chillies, and seedlings, with space beneath shelves for compost storage.

Conclusion

The CHRISTOW Walk In Greenhouse With Shelves is a practical and budget-friendly choice for UK gardeners seeking a compact solution for plant propagation and growth. Its sturdy frame, flexible shelving, and easy assembly make it ideal for small spaces, though users should anchor it securely and expect the cover to need replacement after a few years.

Despite some minor drawbacks like flimsy shelves and limited light transmission, it offers excellent value and functionality for hobbyists looking to extend their growing season.

Christow Small – Plastic Greenhouse

Christow’s small plastic greenhouse is 4 Teir mini greenhouse that is perfect for your indoor or outdoor gardening needs.

This greenhouse can be used in your garden or backyard, patio deck, or even in a suitable spot inside your home.

This mini greenhouse provides the right combination of both light and warmth needed to grow and or start fresh herbs, vegetables, fruits, and flowers.

It’s also great for propagating seeds indoors before transplanting them outside.

Measuring just 19in – 49cm (D) x  27in – 69cm (W) x 62in – 158cm (H) Christow’s small plastic greenhouse will be suitable for the smallest of spaces if things are tight.

This small plastic greenhouse has a few features that make it stand out in the crowd, like the rust-resistant powder-coated tubular steel frame, that easily supports the heavy-duty PE and UV-resistant PVC cover.

The PE cover itself consists of a ‘white’ internal mesh, sandwiched between two layers of polyethene. It’s far thicker than a standard PVC cover, to help reinforce the frame and deliver superior wind resistance and insulation if the greenhouse is placed outside. This in turn helps protect the delicate plants from the harsh weather UK conditions. 

The greenhouse cover has a roll-up door with zippers on either side to easily open and securely close the door flap. Integrated ties allow you to fasten the door when rolled up for easy access, without having any trouble rolling it back down again after use! 

You can also leave the door flap wide open so that air can circulate freely throughout and improve ventilation, temperature, and humidity. Leaving the door flap open will certainly encourage pollination.

The mesh shelves are 13in (33cm) apart, allowing for ample plant growth. These shelves also aid pot drainage and thus prevent possible pot water-logging due to their mesh design.

With its easy click-together design, it does not take too long to assemble, no tools are required either! Just make sure you follow the instructions carefully.

All in all a useful growing space.

Grow It Gardman – 4 Tier Mini Greenhouse

The Grow It Gardman is a 4-tier extra wide arc mini greenhouse. It is a great choice for anyone looking to start growing their own flowers, fruit, and vegetables at home in a small garden or area.

This greenhouse has a strong ‘push fit’ steel frame, which makes it durable and long-lasting. However, as with these small plastic greenhouses, care should be taken when placing the greenhouse and account for wind gusts.

The ‘Grow It Gardman’ features an extra-wide design, allowing you to grow more plants in less space than you would with other mini-greenhouses of such size.

Grow It Gardman

With four shelves, there is plenty of room for your plants to grow! The greenhouse shelves though are in two halves, so you can create more room between shelves if needed which is a great bonus.

Like many small plastic greenhouses of this design, the zipped roll-up door and reinforced polyethene cover (with velcro fastenings)  for easy access. The ‘arc design’ especially, provides room for the taller plants you may want to place inside.

With the ‘arc design’ the dimensions are quite generous for a small plastic greenhouse. Measuring 18in – 45cm (D) x  41in – 105cm (W) x 63in – 160cm (H) there is more than enough room for all the plants you would need to be accommodated within a small mini greenhouse.

Suitable for a patio or decking, even a small backyard or a larger garden the Grow It Gardman is just the ticket. 

Not 100% waterproof it’s as with most small plastic greenhouses the Gardman will benefit from being tethered to a solid wall.

VonHaus – Walk In Mini Greenhouse

The VonHaus walk-in mini greenhouse is a great addition to your garden, providing an ideal environment for growing plants all year round.

Benefiting from a sturdy powder-coated steel frame for extra strength and durability, and a spacious walk-in design, this greenhouse measures a sizable 29in – 73cm (D) x 56in – 143cm (W) x 76in – 193cm (H). With dimensions like this, you simply step inside whenever you need to tend your plants.

This small plastic greenhouse is large enough but small enough for any demanding gardener to place what is needed to be accommodated inside, in most gardening environments.

VonHaus Small Mini Greenhouse

This mini greenhouse comes with a rollup zip panel door that makes it easy to get in and out, and with six strong removable wire shelves, you’ll be able to create a versatile storage solution that’s perfect for both indoor and outdoor use. 

As the shelves are of a wire construction they are easy to clean and maintain, which is a plus point as ‘disease’, particularly in a greenhouse is the gardeners no1 enemy. 

The weather-resistant transparent PVC cover can be a little flimsy, but it should generally protect your delicate plants against frost and snow and safely away from the elements.

Finally and not often offered with small plastic greenhouses, is a manufacturer warranty of 2 years which is fantastic.

Eagle Peak Portable Mini Greenhouse

Is a small plastic greenhouse, that is portable your primary requirement? Then this mini plastic greenhouse model from Eagle Peak is a must.

Small plastic greenhouses do not come much smaller than this at just 35in – 90cm (W) x 95in – 241cm (L) x 35in – 90cm (H). 

The Eagle Peak portable mini greenhouse is a good greenhouse for you to grow your plants, flowers and vegetables, even germinate seedlings. 

Portable Mini Greenhouse

The greenhouse structure is covered in a strong transparent green UV and water-resistant PE plastic, to aid both plant growth and create that ideal growing environment.

In addition, Eagle Peak’s small plastic greenhouse has 1 roll-up ‘zipper’ door and 2 roll-up windows, both held up by ‘loop tapes’. The windows are held closed by strong velcro tape, while the access doors by zippers and velcro tape. 

The door is large enough for you to easily access your plants for watering and moving pots around, while the roll-up windows on either end aid ventilation of your greenhouse when the doors are closed.

The Eagle Peek greenhouse frame is constructed of solid steel pipes, which are powder-coated to ensure durability, and also protect the frames from rust. The frames are easily put together and held in place on the ground with 4no stakes/pegs (provided), we would suggest however adding additional stakes for added security, which can be bought separately. 

With straightforward easy to easy-to-understand instructions provided, this great little greenhouse if fitted correctly resists wind gusts, has great waterproof performance, good heat preservation, and is moisture-proof.

Eagle Peak also offers an exclusive, 1-year limited warranty from the original date of purchase.

Selections Wooden Framed Mini Greenhouse

The Selections Wooden Framed Polycarbonate Growhouse Mini Greenhouse is a compact, budget-friendly solution for UK gardeners looking to protect young plants and extend the growing season.

Designed for small gardens, balconies, or patios, this mini greenhouse features a stained wooden frame with twin-walled polycarbonate panels, offering durability and insulation.

With three shelves, a hinged top, and dual opening doors, it’s practical for seedling propagation and plant hardening.

Plantpak Grow House Mini Greenhouse

It has garnered mixed feedback, praised for its affordability but critiqued by some for assembly challenges and its lightweight construction. Lets take a closer look.

Key Features

Wooden Frame with Polycarbonate Panels

The growhouse is constructed from stained softwood, providing a sturdy yet lightweight frame, paired with twin-walled polycarbonate sheets for UV protection and frost insulation.

Users note it’s aesthetically pleasing but recommend sealing the wood for longevity, as softwood may degrade without maintenance.

Three-Tier Shelving

Equipped with three fixed shelves, the greenhouse offers ample space for seed trays and small pots, some customers wish the shelves were removable for taller plants, but the design suits small-scale gardening needs.

Hinged Top and Dual Doors

The ‘hinged’ lid and two front doors, secured with a fastener, allow easy access and ventilation control. Some customers highlight the convenience but mention occasional issues with door alignment and the toggle fastener’s reliability, suggesting a ‘latch’ upgrade maybe necassary.

Flat-Packed for Home Assembly

Delivered flat-packed, the greenhouse requires self-assembly with a screwdriver, with all screws included. While some users find it straightforward, others report ‘unclear’ instructions and minor fitting issues, recommending patience or extra tools like a hacksaw for adjustments.

Warranty

No specific warranty details are provided by ‘Selections’ for this product. However, purchases are covered by standard UK consumer rights, allowing returns within 14 days for online orders if faulty or unsatisfactory.

Additional Information

  • Size and Weight: The greenhouse measures 3ft 7in high x 2ft 6in wide x 1ft 10in deep (110cm x 76cm x 57cm) and is lightweight at approximately 15.4lbs (7kg), making it portable but prone to tipping in strong winds unless anchored.
  • Colour: Available in a natural brown stain, complementing garden aesthetics but requiring weatherproofing for durability.
  • Ventilation: The hinged top and doors provide adjustable ventilation, though users in warmer climates note the need to keep them open to prevent overheating.

Final Thoughts

The Selections Wooden Framed Polycarbonate Growhouse Mini Greenhouse is an affordable, practical choice for novice gardeners or those with limited space. Its compact design, decent insulation, and ventilation options make it ideal for protecting seedlings and extending the growing season. However, assembly quirks and the softwood frame’s need for maintenance may deter some.

For the price, it’s a solid entry-level greenhouse, provided you’re prepared to invest time in setup and weatherproofing.

Outsunny Steeple Mini Greenhouse

This mini greenhouse from Outsunny is the Outsunny Steeple design, which is a ‘wide and low’ design that can accommodate plant pots with up to 10″ (25cm) diameter.

Measuring 35.5in – 90cm (W) x 106in – 270cm (L) x 35.5in – 90cm (H) the Outsunny is large enough to accommodate your plants, but small enough to fit into most gardens or backyards.

The ‘Steeple’ is made of 1/2in (16mm) diameter powder-coated steel pipe, which makes it sturdy yet lightweight.

As the frame has a powder-coated finish, it’s also resistant to rusting and corrosion, making it ideal for outdoor use.

Mini Greenhouses - Outsunny Steeple

The new and improved green plastic mesh cover is a must for those who want their plants, vegetables or fruits to grow properly. Made of strong water-resistant, ‘anti-tear UV-protecting, material that will also protect against light wind as well as rain while allowing good sunlight through which helps with steady growth rates!

The 3 Rollup doors using ‘integrated ties’  can be tied up if required to aid ventilation. The doors are double ‘zip’ fastening on one side, for smoother opening and closing, making getting in and out of your mini greenhouse quick, easy and convenient.

As an addition, the entire greenhouse plastic cover is ‘overlong’ by 4in (10cm). This additional length cover can be either buried directly in the ground or can have bricks or other heavy objects placed upon it to aid the stability of the small plastic greenhouse.

Like all small plastic greenhouses, the Outsunny needs ‘pegging down’ well with long pegs, to help stabilise the greenhouse further in windy conditions.

The Disadvantages of Small Plastic Greenhouses

Mini-plastic greenhouses are a great way to get started with gardening. They provide the opportunity for small-scale production and experimentation, while still being portable enough that you can take your greenhouse almost anywhere!

One downside of using these small plastic greenhouses is how susceptible they tend to be due to damage from windy conditions. Such conditions can cause covers to rip or tear around ‘greenhouse doorways’ if positioned incorrectly – especially when you have very strong winds coming directly at your greenhouse!

To avoid this problem position these small greenhouses away from common prevailing wind directions or where regular ‘gusts’ may hit. This simple re-positioning will help provide better protection for these small structures; if repositioning is difficult, at the very least position the ‘door side’ away from the most common wind direction in your garden.

Another easy solution to the problem of ‘wind damage’ is reinforcing your mini plastic greenhouse. This can be done using some form of ‘anchor’ or ‘metal pegs’ or simply weighing down the greenhouse with small rocks and or bricks, depending on what type of frame you have. 

Consider the materials that make up your structure (the frame), this will also impact on how well your greenhouse withstands strong gusts from all directions. Powder-coated frames are by far the strongest option, but their price reflects this.

Apart from what has already been mentioned above, there aren’t really any other disadvantages to using small plastic greenhouses, as long as you consider that they can be subjected to acts of nature such as high wind and other extreme weather conditions which might cause them to break easily. 

One last thing about these types of greenhouses is rainwater – if it collects on top then your investment could potentially go down in ruins! So ensure the rainwater falls off your roof easily and does not collect on it.

The Advantages of Small Plastic Greenhouses

Small plastic greenhouses are the perfect size for small-space gardening. They provide an excellent environment for hardening off young plants in the spring and early summer months, making them great to have on hand if you’re growing vegetables and half-hard annual crops. This is because they retain warmth better from being exposed to sunlight for long periods of the day.

A smaller greenhouse can provide warmth for tender summer crops. The heat built up within the plastic greenhouses speeds up the ripening process and helps them grow larger than they would otherwise, things like tomatoes or chillies (or even aubergines) can excel.

There is also some evidence that suggests mini-greenhouses might be better suited towards growing sun-loving vegetables like peppers, but it’s not limited just to these vegetable types! A gardener can cultivate almost any plant in a small plastic greenhouse with the right microclimate.

Starting seeds indoors in a mini plastic greenhouse is much easier than outdoors as well. These small, indoor microenvironments will protect them from all sorts of damage and ensure they grow into healthy plants that can then be transplanted outside when grown enough.

Starting seeds is much easier in a humid environment. You can use fluorescent lights and heat pads to create the perfect setting for an indoor mini greenhouse that will have just what your young plants need. Even though they are small, these mini-greenhouses will provide many more seedlings than propagators.

FAQ’s

How Long Do Small Plastic Greenhouses Last?

The durability of small plastic greenhouses will vary depending on the quality of the materials used in their construction. However, many small plastic greenhouses are designed to be lightweight and portable, making them less durable than larger, more permanent greenhouses.

It is important to choose a greenhouse made from high-quality materials and to provide regular care and maintenance to ensure its longevity.

How Do You Choose The Right Size Small Plastic Greenhouse?

The size of a small plastic greenhouse you choose will depend on several factors, including the number and size of plants you wish to grow, the amount of space you have available, and your budget. 

Consider the dimensions of the greenhouse, as well as the available shelving and storage space, to ensure that it will meet your needs.

Are Plastic Greenhouses Worth It?

Whether a plastic greenhouse is worth it will depend on your individual needs and circumstances. Plastic greenhouses can be a cost-effective option compared to other types of greenhouses, and they are generally easy to assemble and maintain. 

However, they may not be as durable as other types of greenhouses and may require regular replacement.

How Do You Ventilate a Small Plastic Greenhouse?

Ventilating a small plastic greenhouse is important to prevent the buildup of excess heat and humidity, which can be harmful to plants.

You can ventilate a small plastic greenhouse by opening the door or windows provided with the chosen model, or by using a bespoke ventilation system such as a fan or vents in the roof or sides.

It is important to monitor the temperature and humidity levels and adjust the ventilation as needed to provide a healthy environment for your plants

Do Plastic Greenhouses Protect From Frost?

The answer is yes, plastic greenhouses protect plants from frost. Even a small plastic greenhouse will offer enough insulation to ensure that the temperature inside your greenhouse stays at least several degrees higher than the outside temperature.

Therefore it’s safe for your plants during cold winter weather! For severe overnight weather conditions, small plastic greenhouses are normally extremely mobile so they can be brought indoors or perhaps placed in a garage or outbuilding for further ‘protection’ for those delicate plants.

Conclusion

A small plastic greenhouse can be a perfect addition to any garden, small plastic greenhouses make it possible for even the smallest of spaces to produce great healthy plants.

If you’re looking for something that will cut back on your gardening time and help your plants flourish without taking up too much space in your backyard or garden, then these mini-greenhouses could be the answer you have been looking for and we hope this post has been helpful to you!
