Seed trays in a flat
You want several shelves for a seed start in a small room, and a listing with a large UK review file. The DIVCHI four-tier is the top pick for that job. It is a weak outdoor choice if you cannot weight or shelter it.
Indoor greenhouse comparison 2026
The best indoor greenhouses, compared.
Top pick: Barrina 4-tier with lights Best value: DIVCHI 2-tier PVC – Lowest shelf price with a readable UK review set, about £14.29, only when two short shelves are the job. Updated October 2026.
An indoor greenhouse on amazon.co.uk is usually a small covered frame with shelves. A zip-up PVC or PE tent, sometimes with LED bars, holds humidity and a little warmth around seed trays, pots, or houseplants. It is not a hydroponic pod, a heated propagator on its own, or a full glass greenhouse. Ohuhu adds wheels and a stated 10 kg shelf. Judge footprint, tier count, cover, shelf load, and whether a mains lamp has a BS 1363 plug. Read the [indoor greenhouse buying guide](/hub/raised-beds-greenhouses-and-compost/indoor-greenhouse/sub/indoor-greenhouse-buying-guide) for the same criteria in order, without this product table.

The best indoor greenhouses in detail
Our view
Barrina’s CX92Z is the dearest kept listing, at about £79.99, with a title that states 72 W and 5000 K on a four-tier, and 4.5 from only 11 reviews. The bullets describe four 35 cm LED bars, a listing PPFD of 464 µmol/m²/s at 10 cm, a timer, and a hygro-thermometer. That PPFD figure is the manufacturer’s claim on the page, not a measurement from this comparison. Dimensions, cover, and frame are not in the technical block, and the plug type is not stated. Nine UK review blocks were read; praise centres on seed starting with the lights included, set against the price and the small sample. Consider it when a dark room needs one integrated kit and you will confirm a BS 1363 plug, and skip it if you need a printed footprint or a large UK review file.
Pros
- Four 35 cm LED bars, a timer, and a hygro-thermometer in the bullets
- 4.5 from the 11 reviews on the amazon.co.uk listing
- Bullets aim the set at seedlings and houseplants on each shelf
- Item weight stated as 6.26 kg
Cons
- Only 11 UK ratings, and nine review blocks in the file
- about £79.99, the highest price in this set
- Footprint, cover, and frame are not stated
- Plug type is not stated, and the PPFD line is a listing claim
Best for: You want lights, a timer, and a meter in one indoor four-tier and will check the plug before use.
Less suitable: You need a known footprint, a large review sample, or a covered shelf under £40.

Common questions
What size does the Barrina 4-tier with lights listing give?
The technical block does not state dimensions. Item weight is 6.26 kg. Do not treat a missing footprint as a small sill tray.
Does the Barrina 4-tier with lights include a grow light?
Integrated LEDs are stated. The bullets describe four 35 cm bars, a timer, and a hygro-thermometer. Plug type is not stated.
What cover material is stated for B0FYM9Y7TF?
Cover and frame are not stated in the technical block. The title states 72 W and 5000 K on a four-tier.
Our view
The DIVCHI four-tier stands 130 cm high on a 50 by 45 cm footprint, at about £17.29 in the amazon.co.uk export of 20 October 2026, with 4.4 from 634 reviews. Across 50 UK review blocks in the raw file, buyers often mention easy assembly, seed starting, and a compact footprint for that shelf price. The same file records covers that split at a seam or zip, mesh shelves that bend under heavier pots, and a house light enough to blow over outdoors. One detailed UK review says the tubes arrived as plastic, while the technical line lists alloy steel, so the frame is not settled by the title. The printed item weight of 200 g is not a credible mass for an assembled four-tier. In this set it is the top pick when you want four shelves and a large UK review file, and a weak outdoor choice if you cannot weight or shelter it.
Pros
- 50 × 45 cm footprint and 130 cm height across four tiers
- 4.4 from 634 amazon.co.uk reviews in this file
- UK reviews often mention easy assembly and seed starting
- about £17.29 in the 20 October 2026 export
Cons
- UK reviews describe cover splits and mesh that bends
- A detailed review says plastic tubes, against an alloy-steel line
- Light enough to blow over if you stand it in the wind
- Listed weight of 200 g is not a credible assembled mass
Best for: You want four shelves for seedlings in a small room and a listing with hundreds of UK reviews.
Less suitable: You need a stated shelf load, a confirmed steel frame, or a cover you will leave outside in wind.

Common questions
What size does the DIVCHI 4-tier PVC listing give?
The technical line lists 50 × 45 × 130 cm. Item weight is 200 g. Check the bullets if they disagree with that line.
Does the DIVCHI 4-tier PVC include a grow light?
No integrated light is stated.
What cover material is stated for B0CB63QMC4?
The listing says a PVC cover and an alloy-steel frame. One detailed UK review says the tubes arrived as plastic.
Our view
Bamworld’s lighted stand is listed at about £36.99 and 4.23 kg, with a polyethylene cover on a wood frame and 4.4 from 61 reviews. The technical line prints 32 by 16 by 44 cm, and the shelf bullets disagree with that size, so one line is not a footprint you can trust. The bullets describe three LED modes: 48 warm-white 3000 K LEDs, a 660 nm warm mode, and a full warm-white span from 380 to 780 nm. A bullet states 38 lb per shelf. Only five UK review blocks were in the raw file: one long review says the humidity helped a calathea, and others call the LED strips fiddly and the cover short of glasshouse grade. Plug type is not stated. It is a compact lighted option if you measure the shelves yourself and confirm a BS 1363 plug before you switch it on.
Pros
- Three LED modes described on the listing
- 38 lb per shelf stated in a bullet
- 4.4 from 61 amazon.co.uk reviews
- One long UK review credits the cover with humidity for a calathea
Cons
- The technical size and the shelf bullets disagree
- Only five UK review blocks in the raw file
- Plug type is not stated
- LED strips are described as fiddly to place
Best for: You want a small wooden stand with built-in LED modes and will measure the shelves that arrive.
Less suitable: You need one agreed footprint on the page, or a UK 13 A plug confirmed in the listing.

The technical line lists 32 × 16 × 44 cm. Item weight is 4.23 kg. The shelf bullets disagree with that size, so measure the shelves that arrive.
Does the Bamworld 3-tier with LEDs include a grow light?
Integrated LEDs are stated, with three modes in the bullets. The plug type is not stated.

Our view
Ohuhu’s four-tier measures 69 by 48 by 162 cm, lists 3 kg, and costs about £39.99, with 4.3 from 271 reviews. The bullets state 10 kg per shelf and locking wheels, which is the only wheel line in this set. Among 15 UK review blocks, people praise moving it between kitchen and garden, using the cover as an indoor barrier against cats, and a thicker film that holds warmth when it fits. The same notes say wind can topple it outdoors, the brakes feel weak, and some buyers needed pliers or a mallet to fit the wheels. One review mentions incomplete Velcro on the cover, and some say the shelves suit seedlings rather than large pots. It fits when you will roll a taller PVC house indoors and tie it down outside.
Pros
- Wheels stated, and reviews mention moving it between rooms
- 10 kg per shelf in the listing bullets
- 4.3 from 271 amazon.co.uk reviews
- Indoor use as a cat barrier appears in UK reviews
Cons
- Wind can topple it outdoors, and brakes are called weak
- Some buyers needed tools to fit the wheels
- One review reports incomplete Velcro on the cover
- about £39.99, more than double the DIVCHI four-tier
Best for: You want a taller four-tier you can roll indoors, with a stated 10 kg shelf load.
Less suitable: You want the cheapest fixed shelf, or you will leave it on an open balcony without weight or ties.

Our view
The DIVCHI two-tier is the shortest house here, at 50 by 40 by 80 cm and about £14.29, rated 4.1 from 112 reviews. Of 31 UK review blocks, many describe a small-space seed start that is easy to put together and useful as a temporary cover. Reviewers also say tomato plants outgrow the two shelves quickly, and that the frame is not strong enough for larger plants. Cover durability comes up as a criticism, and the mesh is said to flex under weight. The 200 g item weight is not a credible assembled mass. It is the best value only when two short shelves are the whole job. If you will grow tomatoes on, the four-tier at about £17.29 is the clearer spend.
Pros
- Lowest shelf price in the set at about £14.29
- 80 cm height for a low window or a tight corner
- 4.1 from 112 amazon.co.uk reviews
- UK reviews use it for seed starting in small spaces
Cons
- Tomatoes outgrow two tiers in UK reviews
- Cover durability and flexing mesh are recurring complaints
- Listed weight of 200 g is not a credible assembled mass
- No shelf load is stated
Best for: You have a low space and only need two shelves for a short seed start.
Less suitable: You are growing tomatoes or other tall crops on under cover, or you want a stated kilogram load.

Our view
The DIVCHI five-tier lists 59 by 45 by 175 cm at about £23.99, with a clear PVC cover and 4.0 from 11 reviews. Five UK review blocks mention the extra height for taller plants and a theme of overwintering tender plants indoors. The frame material is not stated, there is no shelf-load figure, and the review file is too small to judge how the seams last. At 175 cm it needs clearance to the ceiling, which rules it out of many flats. It sits in the same light PVC class as the cheaper DIVCHI houses, with wind risk if you stand it outside. It is a height option when five shelves matter more than review volume, and it is not the default beside the four-tier at about £17.29 with 634 reviews.
Pros
- 175 cm and five tiers for taller plants
- about £23.99, a modest step above the four-tier price
- Indoor and outdoor use stated on the listing
- Review theme includes overwintering tender plants
Cons
- Only 11 ratings and five UK review blocks
- Frame material and shelf load are not stated
- 175 cm needs real headroom
- Light PVC class, with outdoor wind risk
Best for: You have the ceiling height and want five PVC shelves without paying for lights.
Less suitable: You are choosing on review volume, or the room is tight under a 175 cm cover.

HavenlyCove is a small polyethylene box at about £15.29 and 1.11 kg, with a plastic frame and a magnetic door described in the bullets. The title prints 36 by 22 by 27 cm, while the technical line lists both 27 by 22 by 18 cm and 36 by 22 by 27 cm, so the footprint is not one figure. The raw file has no star line and zero UK review blocks. The bullets say you can stack units vertically or horizontally for herbs and small pots. There is no stated shelf load and no grow light. You can only judge it as a compact sill shelter from the listing text. It is not a tiered seed house, and there is no UK review pattern to lean on.
Pros
- Compact PE box with a magnetic door described in the bullets
- Stackable layout described for herbs and small pots
- about £15.29 and a listed weight of 1.11 kg
- No mains light, so there is no plug to check
Cons
- No star rating and no UK review text in the raw file
- Two size lines appear on the same listing
- No shelf load is stated
- Not a multi-tier stand for seed trays
Best for: You want a small covered box for a windowsill and will measure which size arrives.
Less suitable: You need shelves for seed trays, a UK review count, or one agreed size on the page.

How we compared
Seven indoor greenhouses are on this page. The card scores are the display scores from the amazon.co.uk capture of 20 October 2026. There is no laboratory test. A frost line, a light-transmission percentage, or a PPFD figure is the seller’s text, not a measurement repeated here. HavenlyCove scores 0 because the raw file has no star line and no UK review text, so it cannot take a badge. The four-tier DIVCHI is the top pick. The two-tier DIVCHI is the best value only for two short shelves. The weights below explain how those cards were read. They were not re-run as a new formula.

Indoor greenhouse buying guide
Name the job and measure the room before you compare stars. A two-tier sill cover, a four-tier seed house, and a lighted tent are different purchases. Prices here are amazon.co.uk captures from 20 October 2026, from about £14.29 to about £79.99.
What is an indoor greenhouse?
An indoor greenhouse, on amazon.co.uk and in UK search, is usually a small covered frame with shelves: a zip-up PVC or PE tent, sometimes with LED grow bars. It holds humidity and a little warmth around seed trays, pots, or houseplants. It is not a hydroponic pod, a doll's-house kit, a heated propagator tray alone, or a full glass greenhouse. The seven kept listings run from about £14.29 to about £79.99 in the export dated 20 October 2026.
Best for
- Seed trays on shelves in a room you have measured
- A dark room, if the lamp has a BS 1363 plug you have checked
Not ideal for
- A frost-proof or storm-proof glasshouse
- A compost heap, a hydroponic pod, or a balcony fix that could fall on people below
Mistakes to avoid
- 1
Buying tiers without measuring
A 175 cm five-tier needs headroom. An 80 cm two-tier is a low corner. The floor footprint matters as much as the shelf count.
- 2
Trusting one size line
Bamworld’s technical size and shelf bullets disagree. HavenlyCove prints two size lines. Measure what arrives before you plan the sill.
- 3
Leaving the zip shut, or standing it in the wind
The RHS links still, wet air in a small volume with fungal risk. Open the cover on mild days. A light PVC house needs shelter and weight outdoors. A title that says steel does not erase a review that describes plastic tubes.
What to weigh up
Footprint and tiers
HighSeed trays need shelves you can reach. A sill box is not a 175 cm five-tier. The DIVCHI four-tier lists 50 × 45 × 130 cm. The two-tier lists 50 × 40 × 80 cm. The five-tier lists 59 × 45 × 175 cm. Ohuhu lists 69 × 48 × 162 cm. Barrina does not state a footprint. HavenlyCove lists two sizes.
Cover, frame, light and plug
HighPVC and PE hold moisture, and the zip is the vent on the cheaper covers. Only Ohuhu states 10 kg per shelf. Bamworld states 38 lb per shelf. The four-tier DIVCHI lists alloy steel, and a UK review says plastic tubes. Barrina and Bamworld state LEDs and do not state the plug. Confirm BS 1363 before you rely on a lamp. No listing here is a frost test.
Which option suits you?
Three typical situations, each with a recommendation from this comparison.
A low corner for a short start
You only have room for two short shelves, often under a window. The DIVCHI two-tier is the best value for that job, at 80 cm. UK reviews say tomatoes outgrow it.
A dark room that needs lamps
A north-facing room may need LEDs inside the cover. Barrina lists four light bars, a timer, and a hygro-thermometer. Confirm a BS 1363 plug before you switch it on. The footprint is not stated.
Common questions about indoor greenhouses
Which indoor greenhouse is the top pick in 2026?
The DIVCHI four-tier PVC, about £17.29, is the top pick in this set. It has the highest card score, with 4.4 from 634 amazon.co.uk reviews, on a listed 50 × 45 × 130 cm footprint. That score converts the listing and the review notes. It is not a laboratory result. UK reviews mention easy assembly and seed starting, and also cover splits, mesh that bends, and plastic tubes against an alloy-steel line. It is a weak outdoor choice if you cannot weight or shelter it.
Which indoor greenhouse is the best value?
The DIVCHI two-tier PVC, about £14.29, is the best value, and only for two short shelves. It has 4.1 from 112 reviews and stands 80 cm high on a 50 × 40 cm footprint. UK reviews use it for a small-space seed start and say tomatoes outgrow the two tiers. The four-tier at about £17.29 keeps the top pick because it has the larger UK review file. There is no stated shelf load, and the listed weight of 200 g is not a credible assembled mass.
What should you measure before you buy an indoor greenhouse?
Measure the floor space and the ceiling height before you choose a tier count. A 175 cm five-tier needs clearance that many flats do not have. A single windowsill suits a compact box, not a tall house. Seed trays need shelves you can reach. The RHS treats poor ventilation as a mould risk in small enclosed volumes, so leave room to open the zip on mild days. Buying tiers without measuring is the mistake this set keeps showing.
Do these indoor greenhouses include grow lights?
The DIVCHI houses and the Ohuhu four-tier state no integrated light. Bamworld, about £36.99, lists three LED modes on a wood frame with a PE cover, and the technical size disagrees with the shelf bullets. Barrina, about £79.99, lists four 35 cm LED bars, a timer, and a hygro-thermometer. Neither raw file states the plug type. A north-facing room may need LEDs, and the lamp still needs a BS 1363 plug. The Barrina PPFD line is the seller’s claim, not a figure remeasured here.
Is an indoor greenhouse frost-proof?
No listing in this set is frost-proof, and none prints a frost rating that this comparison repeats as a test. A plain PVC or PE cover has to be safe in normal use under the General Product Safety Regulations 2005. It is not storm-rated by default. These tents hold humidity and a little warmth around trays. They are not a heated propagator and not a glass greenhouse. Keep the plastic off radiators and other direct heat. The listings do not state a clearance distance.
What plug should a lighted indoor greenhouse have in the UK?
UK mains are nominally 230 V, and a plug for a wall socket should be BS 1363 with a BS 1362 fuse. The Electrical Equipment (Safety) Regulations 2016, regulation 35, require a correct UK plug or an approved conversion plug on mains equipment. Bamworld and Barrina both state LEDs, and neither raw file states the plug type. Check the plug before you switch the lamp on. If the plug or fuse does not match, stop and ask a competent person rather than improvising a connection.
Can you put an indoor greenhouse outside?
Several listings say indoor and outdoor use. Ohuhu has wheels, and UK reviews praise moving it indoors and warn that wind can topple it outside. The DIVCHI covers are light PVC. A detailed review on the four-tier says the tubes arrived as plastic, while the technical line lists alloy steel, so do not treat the title as the frame. Weight or shelter a light house if you stand it outside. Do not fix a balcony frame where a collapse could endanger people below.
How is an indoor greenhouse different from a mini greenhouse?
An indoor greenhouse on this page is a shelf tent or a small covered box for a room, usually PVC or PE, sometimes with LED bars. Prices in the set run from about £14.29 to about £79.99. A mini greenhouse is a different comparison, for a freestanding cover rather than shelves in a flat. Use this page for seed trays, pots, or houseplants under a zip cover. Use the mini greenhouse comparison when the job is a small outdoor or patio house. Neither page is a frost test.
Our verdict
Seven listings are shelf tents and one small box, not one glasshouse. The DIVCHI four-tier PVC, about £17.29, is the top pick when you want four shelves and a large UK review file: 4.4 from 634 amazon.co.uk reviews and the highest card score, on 50 × 45 × 130 cm. Reviews still describe cover splits, bent mesh, and plastic tubes against an alloy-steel line. The DIVCHI two-tier PVC, about £14.29, is the best value only for two short shelves. UK reviews say tomatoes outgrow 80 cm. Lighted tents and the five-tier stay separate jobs.
