The best grow boxes, compared.
Top pick: BEIXIFO smart mushroom chamber Best value: VIVOSUN 80x80x160cm tent – Larger reviewed tent under £90, about £84.99, with a higher star line than the 60 cm row. Updated October 2026.
A grow box on this shelf is either a fabric grow tent or a small mushroom chamber, and those are different tools. You use a tent to hold a separate lamp over herbs, chillies, tomatoes, or seedlings. You use a chamber to hold humidity and fresh air for culinary fungi. Tent quality is a metal frame, a reflective lining, a floor tray, duct openings, and a zip that closes. A fully lightproof claim is not a leak test. The two chambers claim a humidity path, and neither has written reviews to check it. The [tent or mushroom chamber guide](/hub/raised-beds-greenhouses-and-compost/grow-box/sub/grow-box-tent-or-mushroom-chamber) keeps that split. None of the four tents includes a lamp, a carbon filter, or an extract fan. A tent is a collapsible cabinet: metal or alloy poles, dark outer cloth, a mylar lining, zips, a window, a floor tray, and sleeves for ducts. Mars names diamond mylar, a shade cloth on the zip, canvas, and a detachable tray on these rows.

Question 1 of 2
What are you growing?
The BEIXIFO chamber is a small acrylic and tempered-glass mushroom box, listed at 39.9 × 26.7 × 33 cm and 6.35 kg for £317.13. The amazon.co.uk line shows 5.0 from two ratings, and there is no review text, so those two stars do not show whether the spray cycle or the fan holds humidity. Bullets claim you set humidity, spray time, and air exchange on an LCD, with a grow light in ten steps and red, blue, or mixed colour, and they suggest a harvest in about seven days. That seven-day line is a listing claim, not a result measured in this comparison. A separate bullet gives 39.8 × 26.9 × 33.2 cm, so the two size lines do not match exactly. The price is several times the fabric tents, and the footprint is a countertop, not a grow room. Consider it only if you specifically want an automated mushroom monotub and you can live with two ratings and no written UK reviews. It is the wrong spend if you wanted a 60 cm plant tent and a separate lamp.
Pros
Cons
Best for: You want a countertop mushroom chamber and will treat the automation claims as untested in this comparison.
Less suitable: You need a fabric plant tent, or you want a price under £120 with a large UK review file.
Specifications
Common questions
What size is the BEIXIFO chamber on the listing?
Bullets give 39.8 × 26.9 × 33.2 cm and the technical line says 39.9 × 26.7 × 33 cm at 6.35 kg.
Does the listing include written reviews?
The amazon.co.uk line shows 5.0 from 2 ratings and there is no review text to check the automation claims.
What does the listing say is automatic?
Bullets claim automatic humidification, spray cycles, air exchange, and a grow light with ten brightness steps controlled on the LCD module. Those lines are seller claims.
The VIVOSUN listing is an 81.3 × 81.3 × 160 cm fabric tent at £84.99 and 7.71 kg, with 4.5 from 1,266 amazon.co.uk reviews. That is a higher star line than the Mars Hydro tents here, and the extra width plus 160 cm of height gives more canopy room than the 60 cm square. The bullets describe Oxford canvas, reflective mylar, a plastic viewing window, a removable floor tray, duct openings, and two hanging straps, and they claim each top bar can hold up to 100 lb. Only a handful of the saved review texts are from the United Kingdom, and those mention assembly and daily use rather than a pattern of faults, so the 1,266-review star line is much larger than the written UK sample on this listing. The included line is a removable mylar tray, not a lamp, and a 220 watt light-source field on the page is not a lamp in the box. It is the best value pick when you want a reviewed tent under £90 that is larger than 60 cm square. Skip it if your ceiling cannot clear about 160 cm plus a little room above the tent, or if you needed a long file of written UK comments on this exact ASIN.
Pros
Cons
Best for: You have floor space for about 82 cm square and want a larger tent that is still under £90.
Less suitable: Your ceiling is tight, or you wanted dozens of written UK reviews for this ASIN.

Common questions
Does this listing include a grow lamp or extract fan?
The included line is a removable mylar tray, not a lamp, carbon filter, or extract fan. A 220 watt light-source field on the page is not a lamp in the box.
What footprint does the technical line give?
The listing technical line says 81.3 × 81.3 × 160 cm.
Is there a floor tray?
Bullets and the included line describe a removable waterproof floor tray.
The Mars Hydro 60 × 60 × 140 cm tent is the compact fabric shell in this set, listed at £56.99 and 5.63 kg, with 4.4 from 1,981 amazon.co.uk reviews. Nearly all of the saved review texts on this listing are from the United Kingdom, and they often mention the build, the ports and vents, and a setup reviewers describe as straightforward. The same reviews also record zipper trouble, light at the vents, a frame that felt weak, and rust or peeling, so the bullet about a perfect light lock is not what every buyer reports. The included lines name a removable floor tray and a viewing window, not a lamp, carbon filter, or extract fan. One UK review of this £56.99 tent says the box has neither a fan nor lights. In this six-listing comparison it is the top pick when you want the smallest Mars Hydro footprint with the fullest UK review file. It is the wrong row if you need 180 cm of height or a mushroom chamber.
Pros
Cons
Best for: You want a 60 cm square fabric tent for herbs or seedlings and will buy the lamp and fan separately.
Less suitable: You need 180 cm of height, or you are fruiting mushrooms rather than growing leafy plants.

The Mars Hydro 120 × 60 × 180 cm tent is the long spare-room shell in this set, listed at £119.99 and 9.24 kg, with 1.3 cubic metres given as chamber volume. The amazon.co.uk star line reads 4.4 from 1,981 reviews, the same count as the 60 cm Mars Hydro row, and the saved review bodies repeat that smaller tent’s texts. You should not treat a comment about a shorter tent, or a five-to-ten-minute setup, as proof that this 180 cm model behaves the same way. The title and model MARS-GT-120*60 are what fix the size, because the technical dimensions field was empty. Bullets still describe reflective mylar, a zipper flap, a floor tray, and a viewing window, and they do not list a lamp, fan, or carbon filter. Buy it when you have measured a 120 × 60 cm floor and about 180 cm of height plus clearance. Leave it if you only have a cupboard, or if you wanted review text that is clearly about this ASIN alone.
Pros
Cons
Best for: You have a spare room for a 120 × 60 cm floor and 180 cm of height, and you will buy the lamp separately.
Less suitable: You are fitting a cupboard, or you need reviews that name this ASIN only.

Common questions
Does this listing include a grow lamp or extract fan?
The bullets name a floor tray and a viewing window, not a lamp, carbon filter, or extract fan.
What footprint does the technical line give?

Is there a floor tray?
The bullets describe a removable floor tray and a viewing window.
The Oairgico tent is the smallest fabric shell here, 55 × 40 × 65 cm at £42.90 and 1.53 kg, with 4.0 from 117 amazon.co.uk reviews. The listing gives a chamber volume of 143 litres and describes viewing windows, a floor tray, cable holes, ventilation openings, and hanging points, including use as a cover for countertop hydroponic gardens. Saved UK texts call it a seedling tent, or describe a weak frame whose floor and roof do not seal, and those comments most often criticise the size, with one light-leak mention. At 65 cm tall it will not take a full-size lamp, extract fan, and plant the way an 80 cm or 140 cm tent will. The box does not include a lamp. It can cover a very small pot or a countertop garden if you have already accepted that 55 × 40 cm is the whole floor. It is a poor substitute for the 60 cm Mars Hydro if you wanted height for a hung lamp.
Pros
Cons
Best for: You are covering seedlings or a small countertop garden and have measured a 55 × 40 cm shelf.
Less suitable: You want to fruit tomatoes, or you need room for a ducted fan and a hung lamp.

The MUALROUS listing is a foldable mushroom chamber at £120.99 and 2.66 kg, not a reflective plant tent. The bullets claim automatic humidity control, two built-in fans, a clear front door, and use for shiitake, oyster, enoki, and reishi. The listing has no external size line and no amazon.co.uk star line, and no UK review texts were saved, so you cannot check whether the fans or the humidity control work. The title spells the design “fordable”, which is the listing’s own wording for a box you fold away. Plug type and wattage are not stated, so you would still need to confirm the mains lead on the live page before you treat it as a UK appliance. It is only worth a look if you are fruiting culinary mushrooms and can accept an unreviewed listing with no published footprint. It will not replace a Mars Hydro or VIVOSUN tent for leafy plants under a grow lamp.
Pros
Cons
Best for: You want a mushroom fruiting box and will verify the footprint and the plug on the live amazon.co.uk page.
Less suitable: You are growing herbs or leafy plants and need a reflective tent with a separate lamp.
Specifications
Common questions
What does the MUALROUS listing include?
Bullets claim humidity control, two fans, a clear door, and a foldable body for named culinary mushroom types. No external size line was published on the technical block.
Is there an amazon.co.uk star line?
This listing has no customer-reviews star line, so stars and written UK feedback are not available from the page we read.
Is this a fabric grow tent?
No. It is listed as a mushroom cultivation box rather than a reflective plant tent.
Six amazon.co.uk listings were read on 19 October 2026. The number on each card is only the star line scaled to 100, so 4.4 becomes 88 and a listing with no review line scores 0. That number is not a light-leak or humidity test. The weights below are how the top pick and the best value were chosen once each inside this set.

Choose the organism first, then the floor and the ceiling, then check what the box does not include. A star line does not cross from a plant tent to a mushroom chamber.
A grow box on this shelf is either a fabric grow tent or a small mushroom chamber. A tent is a collapsible cabinet: metal or alloy poles, dark outer cloth, a mylar lining, zips, a window, a floor tray, and sleeves for ducts. You use it to hold a lamp you buy separately over herbs, chillies, tomatoes, or seedlings. Mars Hydro names diamond mylar, a shade cloth on the zip, 1680D canvas, and a detachable tray on these rows.
A £56.99 plant tent and a £317.13 mushroom chamber are different tools. Stars on one do not prove the other.
None of the four tents lists a lamp, a carbon filter, or an extract fan. A wattage field is not a lamp you can unpack.
The saved texts on the 120 × 60 × 180 cm listing repeat the 60 cm reviews. They are not a separate UK sample for the taller tent.
UK comments treat the Oairgico as a seedling tent. At 65 cm tall it will not take a hung lamp and a fruiting plant.
A reflective tent is for green plants under a lamp you buy separately. A mushroom chamber is for fungi. The MUALROUS row names shiitake, oyster, enoki, and reishi, and it has no star line. The BEIXIFO row claims an LCD, spray, and a ten-step light, with 5.0 from two ratings and no review text. Do not let that star line outrank a tent that has 1,981 reviews.
Oairgico is 55 × 40 × 65 cm. Mars Hydro is 60 × 60 × 140 cm or, on the long row, 120 × 60 × 180 cm from the title because the technical dimensions field was empty. VIVOSUN’s technical line is 81.3 × 81.3 × 160 cm. HomeGrower’s retailer table treats 60 × 60 cm as a compact herb and chilli tent and 80 × 80 cm as a small home tent. That is a rule of thumb. Leave clearance above the fabric, and do not block a door or a smoke alarm.
Three typical situations, each with a recommendation from this comparison.
You want herbs or seedlings in a small footprint and you will buy the lamp and the fan yourself. The Mars Hydro 60 × 60 × 140 cm tent is the top pick for that job. The 55 cm tent is only a seedling cover, and 65 cm of height will not take a full lamp and a plant.
You have floor for about 80 cm square and ceiling clearance above 160 cm. The VIVOSUN tent is the best value under £90 for that larger shell. You still buy the lamp, the carbon filter, and the extract fan, and the written UK sample on this ASIN is thin.
You are fruiting oyster, shiitake, or enoki, not leafy plants under a lamp. The MUALROUS and BEIXIFO rows are seller claims with no written reviews. Check the footprint and the UK plug on the live page before you pay, or use a simple monotub, which is not in this set.
Inside these six amazon.co.uk listings, the Mars Hydro 60 × 60 × 140 cm tent is the top pick: about £56.99, 4.4 from 1,981 reviews, and the fullest set of saved UK texts. The VIVOSUN tent is the best value when you want more floor under £90 and can accept a thinner file of written UK comments. The two mushroom chambers stay seller claims, with two ratings on one row and no star line on the other. Measure the room, then buy the lamp and the fan separately if you chose a tent.
VIVOSUN 80x80x160cm tent
Larger reviewed tent under £90, about £84.99, with a higher star line than the 60 cm row.
