If your indoor tomatoes are outgrowing a compact enclosure, the Gorilla grow tent Pro 3×3 offers a clear attraction: more height without a much wider footprint. TheOneGrow’s 90 × 90 × 180 cm tent takes the simpler approach, keeping a small home setup within a fixed height. These two designs serve different priorities even though their floors are almost the same size.
For most compact South African home layouts, I would start with the TheOneGrow 90 cm tent. Choose the Gorilla Pro 3×3 when extra vertical space is the feature you actually need. TheOneGrow’s 120 × 120 × 200 cm tent is the useful alternative when plants need more room sideways as well as upwards.
This is an editorial comparison of published specifications, not a hands-on test. The important differences are the usable dimensions, construction specification, ventilation openings and purchase route; none requires treating a larger number as an automatic win.
Which tent gives you more useful growing space?
The Gorilla grow tent Pro 3×3 has a 91.44 cm square footprint and a base height of 210.82 cm. Against TheOneGrow’s 90 cm square, 180 cm tall model, the floor gains only about 3.2%, while total height increases by 30.82 cm. Height is the meaningful advantage here.
That makes Gorilla appealing for taller plants, deep containers or an arrangement where equipment crowds the roof. TheOneGrow’s advantage is a lower enclosure that is easier to accommodate beneath room obstructions. For compact herbs or shorter pepper varieties whose height budget already fits, the extra roof space is less compelling.
| Feature | Gorilla grow tent Pro 3×3 | TheOneGrow 90 cm tent | TheOneGrow 120 cm tent |

| Dimensions | 91.44 × 91.44 × 210.82 cm | 90 × 90 × 180 cm | 120 × 120 × 200 cm |
| Nominal floor area | About 0.836 m² | 0.81 m² | 1.44 m² |
| Height options | 241.30 or 271.78 cm extended | Fixed 180 cm | Fixed 200 cm |
| Outer fabric specification | 1680D | 600D Oxford | 600D Oxford |
| Frame pole diameter | 19 mm | 16 mm steel | 16 mm steel |
| Ventilation specification | Six 11-inch duct ports | 4 or 6-inch fan compatibility | 6-inch fan compatibility |

| Listed product price | R6,099; includes 12-inch extension | R1,825 | R2,335 |
TheOneGrow 120 cm model gives substantially more floor space than either small option, but cannot replace them in a narrow corner. Its advantage is a wider plant arrangement; the Gorilla grow tent keeps that arrangement compact while extending upwards.
A 240 cm ceiling illustrates the trade-off. Gorilla’s 241.30 cm extension configuration is already too tall, before assembly clearance is considered. The base Gorilla and both TheOneGrow sizes fit numerically. Pots, suspension and the light’s required canopy gap still consume part of their internal height.
Is Gorilla’s construction specification worth choosing?
The Gorilla grow tent lists heavier fabric and poles and supports extra height. If you do not need the extension and your equipment fits within TheOneGrow's load limit, TheOneGrow is sufficient.
- Fabric specification: higher for Gorilla. Gorilla lists 1680D fabric; TheOneGrow lists 600D. Denier describes yarn linear density, not the lifespan of the complete enclosure.
- Pole diameter: larger for Gorilla. The Gorilla grow tent uses 19 mm poles versus 16 mm. Wall thickness, connectors and installation also affect the frame.
- Frame detail: clearer from TheOneGrow. It lists a 0.8 mm tube wall, steel three-way connectors and load limits of 15 kg for 90cm and 25 kg for 120cm.
- Hanging load: not directly comparable. Gorilla publishes a higher figure, but the brands do not share one test. Follow each product's limit.
- Best use: Prioritise the Gorilla grow tent when its extension, 19 mm poles and 1680D fabric solve a real need. Otherwise, TheOneGrow supports a conventional small setup within its stated load.
Which design is easier to equip and use?
Decide from the required duct routes, daily access and available ceiling height.
- Ventilation ports: more routes from Gorilla. The Gorilla grow tent Pro 3×3 lists six double-cinching 11-inch duct ports. A large port does not require an 11-inch fan.
- Electrical access: clearer from Gorilla. Two 3-inch ports provide defined cable routes for lights, fans and sensors.
- Conventional extraction: covered by TheOneGrow. The 90cm model supports 4- or 6-inch fans; the 120cm supports 6-inch connections. Port size does not promise airflow.
- Viewing and storage: straightforward on TheOneGrow. A front opening, viewing window and side tool pocket support routine care.
- Vertical space: more flexible on Gorilla. Its taller enclosure and extension hardware help when plants and suspended equipment need extra height.
- Door count: follow the model table. It records one door, so this comparison does not claim the rear access mentioned in generic copy.
- Recommendation: Choose the Gorilla grow tent for multiple routes and extendable height. Choose TheOneGrow for front access, conventional extraction and fixed height. Leave clearance for doors and ducts; use the grow tent selection guide to check the room.
Which purchase makes better sense in South Africa?
Compare the budget, required floor area and whether the extension solves a real height problem:
- Choose TheOneGrow 90cm for a compact setup. Futurama's Gorilla 3×3 with a 12-inch extension kit is R6,099. TheOneGrow 90cm is R1,825, saving R4,274 or about 70.1%. Both prices cover enclosures, not lights and ventilation.
- The Gorilla grow tent premium mainly buys height and construction specifications. It includes the taller enclosure, 1680D fabric and extension kit. Pay for those features when they solve a real installation need.
- Choose TheOneGrow 120cm for a wider layout. At R2,335, it is R3,764 or about 61.7% below that Gorilla listing and provides 1.44m² of floor area. It is a larger-floor alternative rather than an identical-size replacement.
- Moving from 90cm to 120cm costs R510 more. That difference adds 20cm of height and more floor space for buyers who know the 90cm layout is too narrow.
If your room is compact, choose the TheOneGrow 90cm grow tent. Move up to 120cm when your plants need a wider growing area. The higher Gorilla grow tent price makes sense when plant height or light suspension genuinely requires the extension structure.
Conclusion
The Gorilla grow tent carries a substantial height-and-extension premium. Save R4,274—about 70.1% on listed product prices—with the TheOneGrow 90 cm tent for its small footprint, clear rand price and documented equipment limits. For wider planting, choose the TheOneGrow 120 cm tent: the R510 difference buys a larger floor and 20 cm more height.
FAQ
These questions cover the remaining differences between the product specification and what a particular setup needs.
How tall is a Gorilla grow tent?
The Pro 3×3 is 210.82 cm tall at its base setting. Published extension configurations reach 241.30 cm or 271.78 cm. These figures apply to this model, rather than every tent carrying the brand name.
Is a Gorilla grow tent extension worth the expense?
It is worth considering when insufficient usable height is the limiting problem and the room accepts the extended enclosure. If a 180 cm or 200 cm fixed-height tent already accommodates your equipment and plants, the extra height adds less practical value.
Does 1680D mean Gorilla lasts longer?
It establishes a different yarn specification from 600D, not a measured lifespan. Seams, zippers, frame design and use also matter. This comparison does not award either brand a durability result without comparable testing.
Are lights and ventilation included with TheOneGrow?
The two products compared here are single tents with their support frames. Lighting, ventilation and growing accessories are selected separately. Compare a kit only after separating its equipment from the enclosure price.
