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.

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 £219, 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 £324

Frequently asked questions
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.
