What is a mini greenhouse used for?

Raising seedlings, hardening off, and growing a little salad or herbs. A mini greenhouse extends the season in a tiny space, perfect for a patio, balcony or doorstep where a full greenhouse will not fit.

Do mini greenhouses actually work?

Yes, very well for their size. The enclosed warmth gives an earlier start and protects tender plants. The key is ventilation, as they overheat fast, so open them up on sunny days.

How do I stop a mini greenhouse overheating?

Open the cover or vent early on bright days. With so little air inside, temperatures spike quickly even in spring. A small thermometer helps, and shading the cover in high summer prevents scorch.

Will a mini greenhouse blow away?

It can if left light and loose. Weigh the base shelf with slabs or strap the frame to a wall. Once anchored and loaded with pots, a mini greenhouse stays put through normal weather.

What can I grow in a mini greenhouse?

Seedlings, bedding plants, herbs, salad leaves and a few chillies or a compact tomato. Grow upward on the shelves to make the most of the height in such a small footprint.

Mini Greenhouses

Maximise your harvest in tight spaces with our vertical mini greenhouses. Ideal for balconies and patios, these structures offer the height required for tomatoes and peppers where standard greenhouses won't fit.

We stock durable aluminium models from Access, Elite, and Vitavia featuring sliding doors and adjustable shelving. Unlike cheap plastic covers, our range uses Toughened Safety Glass or polycarbonate for long-term weather resistance and safety. Available as freestanding units or wall-mounted lean-tos with Free UK Mainland Delivery.

Choose by what you will stand it against. Wall-mounted frames need masonry fixings, not fence panels. Freestanding units want two level slabs in a sheltered spot. Check tier spacing before you buy — tomatoes need the height of two shelves removed. If you have 6ft of ground spare, a small greenhouse gives standing room for similar money. A cold frame suits hardening off at ground level. A full-height lean-to greenhouse uses the same wall with far more growing space. Or browse the full greenhouse range.

Very helpful. Great delivery. Looks good:
we will see after I’ve built it.

Verified Customer

The greenhouse parts plus glass arrived safely packed.
We erected the greenhouse ourselves and after a couple of initial errors we got into the swing of it and are really pleased with the results.
The diagrams in the instruction manual could be clearer but we got there, though it did seem to take many hours.

Verified Customer

Verified Customer

Verified Customer

Extremely helpful, could answer all my questions and give advice. Delivery was first class, one of the best delivery companies I've dealt with if not the best.
Product is fitted and looks great.

Verified Customer

It was easy to choose the greenhouse itself and then the extras. Hassle free and it was delivered when expected. I would however advise that you may want to hire someone to put it together for you, unless you are good at following this sort of instructions. The greenhouse looks fantastic and I am very happy to have bought it. I would recommend the Greenhouse Stores.

Verified Customer

Verified Customer

ordered a 4x6 greenhouse which was delivered on time. My son put it up in a day and it looks lovely. Can't wait for the next spring growing season.

Verified Customer

Great in communication. Attentive. Concrete base layer needed and link to him enabled him to do it. Lean to greenhouse efficiently assembled. Highly recommended

Verified Customer

Brilliant service from start to finish and a slight issue with my order was resolved extremely quickly great service

Verified Customer

Great product and straight forward to assemble, would suggest a few addition 3D views in the assembly manual but thats only so you can confirm which orientation you are working on. Also make sure the base is securely fixed prior to the build and ensure you are within 1mm on corner to corner measuring so you know you are square before you start building up. Some of confusion on some of the instructions as the description can be read several ways. All in all a very simple build. Only concern is how it acts in strong winds, I have positioned mine adjacent to a fence on one side and a structure at the rear to try and reduce the potential for wind causing damage

Verified Customer

Absolutely love my greenhouse. Fast delivery, very helpful friendly delivery driver. Good communication. Fast to get back to me when emailed with problem putting together. Thank you

Verified Customer

From ordering to delivery went fine had a phone call to let me know when delivery was coming. And it was on time.

Verified Customer

Was waiting for over a week for delivery from order date but apparently this is the norm with this company so be aware if you want it quick - delivered well boxed- no damage- no parts missing - husband assembled by himself and found it easy - couldn't find a small compact one like this on other websites and if available on other sites no shelves available which we feel you need - overall very pleased with purchasing method and product - enclosed pictures so other customers can gauge storage

Verified Customer

Greenhouse Stores were the answer to my prayers. Amazing people who went above and beyond to satisfy my requirments and to ensure that I was happy with everything from ordering to having the Greenhouse put up. Top class from start to finish and wouldnt ever go anywhere else.

About Our Mini Greenhouses

A mini greenhouse is growing under glass stripped to its smallest, for a patio, balcony, doorstep or the corner of a yard. These are the wall-mounted lean-tos, tiered growhouses and compact units that fit where a walk-in never could. We stock 54 of them, from £229, by Access, Vitavia, Elite and Palram Canopia. For a bit more room, step up to our small greenhouses.

At this size every inch counts, so the smart move is to build height rather than spread. A tiered or wall-mounted unit stacks several growing levels into the footprint of a doormat. Glaze it in polycarbonate or toughened glass if it lives somewhere exposed or busy, and give it a sheltered, sunny spot out of the wind.

Why We Chose This Range

"A mini greenhouse is the one I recommend to people who say they have no room, because nearly everyone has a sunny wall or a doorstep. The mistake is leaving them to cook: a tiny enclosed space hits 40 degrees in spring sun and fries the seedlings inside. Prop the cover open on warm days, or pick a model with a proper vent. Treated right, a mini will raise all your bedding and a crop of salad from almost nothing."

— Matt, Founder of Greenhouse Stores

💡 Tip: Weigh down or anchor a lightweight mini greenhouse. They are easily tipped by wind before they are loaded with pots. A couple of slabs on the base shelf, or a strap to the wall, keeps it where you put it.

🔧 Matt's Installation Tip: Mind the spring heat

The biggest killer of mini-greenhouse plants is not cold, it is heat. With so little air inside, the temperature spikes the moment the sun is out. Open the cover or door early on bright mornings, even in March, and close it again at dusk. A small thermometer inside takes the guesswork out.

Matt's Pick: Access Westminster Mini Lean-To

Best For: A sunny wall, patio or balcony with no floor to spare.

Why I Recommend It: It bolts flat to the wall, takes up almost no ground, and the toughened glazing makes it safe and warm enough for an early start.

Price: from £328
