Tomato greenhouse UK
Updated: October 2026
You have grow bags or a narrow bed, cordon tomatoes that want height and air, and a search that also offers twelve-shelf tents. A tomato greenhouse UK buyers can actually use is deep enough for the bag and tall enough for the plant, not a cupboard of 40 cm gaps with the word tomato in the title. The listings below are from the [Gardebruk greenhouse comparison](/hub/raised-beds-greenhouses-and-compost/gardebruk-greenhouse). None of them is a Gardebruk greenhouse. Peter F. took dimensions and review counts from those amazon.co.uk listings, updated 20 October 2026. No crop was weighed and no temperature lift was recorded. A qualifying purchase can earn a commission at no extra cost to you.

What tomato growing needs here
A cordon in a bag needs a footprint you can stand a 50-litre bag in, a path to water it, and air when the sun is on the cover. In this set that points to a sleeve about 50 to 80 cm deep and as long as the row, or to a square walk-in you can guy to a fence and keep clear of shelves. It does not point to a four-tier patio tent. The RHS notes that a north–south house suits summer tomatoes because the sun comes from the east and the west across the row. That is orientation for a house you can site, not a promise about yield. Which? talks about a 6 × 8 ft walk-in when the crop is tall plants in a border. That width is a different object from a 100 cm sleeve. Use it as a contrast, not as a size you will find in the £23 listing.
Narrow tomato houses in this set
Two listings are sold as tomato or row covers rather than shelf tents. The VOUNOT at £23.49 is 100 × 50 × 150 cm, with a stated 135 g/m² PE cover, a rear V-brace, a roll-up zip, four ropes, stakes and ties. It weighs about 2.7 kg. Across 4.4 from 145 amazon.co.uk reviews, 14 UK texts praise the size for a few plants and quick assembly. The same notes report zips leaving the track, a flimsy frame, water through the cover and wind lift. At 50 cm deep and 150 cm high you cover one bag from outside. A tall cordon will press the roof unless you stop it or choose a shorter variety. Fifty centimetres is enough for a single bag along the length. It is not enough for two bags side by side.
The Ohuhu at £49.99 is 200 × 77 × 170 cm, 130 g/m² PE, 16 mm tubes, mesh windows, stakes and ropes, about 3 kg. Across 4.3 from 814 reviews, 48 UK texts praise a tied-down frame and the length of the row. You still stoop, because 170 cm is under many adult heads, and you still see missing parts, zip failure and blow-outs. Seventy-seven centimetres gives the bag a little more shoulder room than 50 cm and still no aisle. A 130 or 135 g/m² figure is the cloth weight on the listing. It is not a requirement invented for tomatoes, and it is not a wind class. Both houses need the stakes in soil. On paving you weight the skirt, which the anchoring guide covers.
When a shelf tent is wrong
The heyfurni is 143 × 73 × 195 cm with six mesh shelves and about 40 cm of vertical space, at £49.99. That gap fits a tray of seedlings. A cordon tomato in June is taller than 40 cm and wants the string above the bag, not a wire shelf through the stem. The UK sample is only 25 reviews, and the texts include mould when the zip stays shut, which is a bad habit around leaves that already struggle with blight-prone weather. The JUNGLE STONE at 145 × 75 × 195 cm lists ten shelves and mentions tomatoes in the title. The depth and the shelves still make it a nursery. The DIVCHI at 105 × 45 × 160 cm is a four-tier herb shelf. It is the top pick in the main comparison for patio trays, and it is the wrong pick for fruiting tomatoes.
The twelve-shelf Ohuhu at 145 × 145 × 195 cm is large enough to stand in and still the wrong layout if every shelf stays in. You can remove shelves and stand bags on the floor. You have then paid £69.99 for a square cover and a pile of unused grids, which can be reasonable if you also raise seedlings, and wasteful if the only crop is four cords. The wide VOUNOT at 143 × 215 cm, with four shelves you can take out, is the cloth house that turns into an open bay. That choice sits with the other shapes on the best walk-in greenhouse page.
Heat and the door
Tomatoes in a shut zip tent on a sunny British day stall or scorch. The vent on these sleeves is the roll-up door and, on the Ohuhu, mesh windows. Open the door while you are on the plot. Tie it so the windward side is not a sail. Water in the morning. There is no temperature rise to quote, and no claim that a 135 g/m² cover replaces a heated glasshouse. If the leaves are wet every evening because the only way to cool the tent is a door you forget, you will spend the season wiping condensation, not picking fruit. The daily sequence is the same as the anchoring guide. Read it once before the first hot weekend, not after the first cooked truss.
When to step up to a walk-in
Step up from the 100 × 50 cm VOUNOT when you have more than a couple of bags, you want to stand beside them, or 150 cm of headroom is pinching the variety you grow. The Ohuhu at 200 × 77 cm is the longer row inside the same idea. Step up to a square cloth house, the twelve-shelf Ohuhu or the wide VOUNOT with shelves removed, when you need an aisle and you will guy the frame to a fence on an allotment. Step up to polycarbonate when the house has to stay through winter and you have checked Planning Portal height limits. A 6 × 8 ft glazed house is the Which? picture of border crops. It is not what £23 buys.
Common questions
Is 100 × 50 cm deep enough for tomatoes?
It is enough for one row of grow bags, which is what the VOUNOT at 100 × 50 × 150 cm is sized for, at £23.49. It is not enough for two bags side by side or for you to step inside. A tall cordon can hit the 150 cm roof. If your plants usually finish above that, use the Ohuhu at 170 cm or a square house you can stand in.
Can I use a twelve-shelf walk-in for cordon tomatoes?
Only if you take shelves out and put the bags on the floor. The Ohuhu at 145 × 145 × 195 cm is a shelf house first, with a stated 10 kg load and 4,257 reviews. Left fully shelved, the gaps fight a cordon. The heyfurni’s 40 cm gap is the clearer version of that mistake.
Grow bags or soil inside a narrow house?
Bags. The 50 to 77 cm sleeves are covers over containers, not raised beds you fill with a yard of compost. A bag sits on the ground, you water it from the door, and you stake the frame outside the bag so the cane and the tent pole are not the same stick. Loose soil in a 100 cm tent has nowhere to hold.
Which listing is sold explicitly as a tomato house?
The VOUNOT title is a tomato grow house, 100 × 50 × 150 cm, 135 g/m². The Ohuhu title is a walk-in tomato greenhouse, 200 × 77 × 170 cm, 130 g/m². The JUNGLE STONE mentions tomatoes and then sells ten shelves in 75 cm of depth. Trust the dimensions over the crop word.
When should I move to a square walk-in instead?
When you need an aisle, more than one row, or headroom to work the plants standing up. The wide VOUNOT at 143 × 215 × 195 cm and the square Ohuhu at 145 cm are the cloth options in this set. Remove shelves if the crop is bags. Stay with the sleeve if the bed is a single strip and you are happy working from outside.
