The HOMEbox Ambient R240+ is a 2.4 x 1.2 x 2.2m (8x4) rectangular grow tent with 2.88m² of grow space — the extra-height version of the R240, adding 20cm of headroom over its two side-by-side 1.2m lighting zones. German-designed with HOMEbox's PAR+ reflective inner lining, a 150kg load-rated frame, dual Ø300mm roof ports, and four OmniFlow airvents, it's built for dual-light setups and serious perpetual rotations where taller plants need room to stretch.

Extra 20cm HeightAt 2.2m tall, the + version gives taller plants and bigger fixtures the headroom the standard R240 can't.
2.88m² Grow SpaceThe 8x4 footprint runs two full lighting zones side by side — double the canopy or a staggered rotation.
150kg Load RatingDouble the Q-series rating — the Ø22mm frame carries two lights, a big fan and filter without flex.
PAR+ Reflective LiningHOMEbox's optimally reflective inner coating directs more plant-usable light back at your canopy.
Dual Side AccessFull zipper access on both left and right sides — every corner of the 2.4m canopy stays reachable.
Four MicroMesh AirventsFour OmniFlow airvents with 700 micrometre insect mesh keep passive intake flowing across the full length.

Grow Guys Tip — Kitting Out an R240+
  • Run two LEDs, one per 1.2m zone — 600W–1000W each depending on how hard you push. Our pick is a pair of Treegers GL650W+, and the 2.2m height keeps hanging distance comfortable even in late flower.
  • A 200mm (8") extraction fan and carbon filter handles the volume. The Vivosun AeroZesh kit in 8" covers fan, filter and ducting in one box.
  • Both zones share one light schedule, but dimmable lights let you run each end at different intensity — handy for staggered plant sizes in a perpetual rotation.

Setting Up Your R240+

1Clear a level 2.4 x 1.2m floor space with at least 2.2m of ceiling clearance, then assemble the Ø22mm frame poles and corner connectors — no tools needed.
2Pull the canvas over the frame from the top down and zip it closed, keeping tension even across the long sides so the corners seat properly.
3Hang a light over each 1.2m zone and mount your extraction fan and carbon filter, running ducting out one of the Ø300mm roof ports.
4Open the OmniFlow airvents for passive intake along the full length, cinch unused ports closed, and check for light leaks with the lights on and room lights off.
5Dial in your environment — temperature, humidity and airflow — before plants go in. Bigger tents hold more air but also hide dead spots; check both ends.

Frequently Asked Questions

Is the HOMEbox Ambient R240+ an 8x4 grow tent?

Yes. At 240 x 120cm the R240+ is the metric equivalent of an 8x4 (8ft x 4ft) grow tent, with 2.88m² of grow space and a taller-than-standard 2.2m height.

Will the R240+ fit under a standard Australian ceiling?

Yes. Standard Australian ceilings are 2.4m, leaving around 20cm of clearance above the 2.2m tent — enough to assemble it in place. Check your ceiling height first if the room has bulkheads, downlights or a lower ceiling.

What is the difference between the R240 and the R240+?

Height, plus one extra side port. Both share the same 240 x 120cm footprint and 2.88m² grow area — the + version stands 2.2m tall instead of 2m and adds a second Ø250mm side port for more ducting flexibility.

What lighting suits the R240+?

Two LEDs of 600W to 1000W each, one over each 1.2m square zone. Our light of choice is a pair of Treegers GL650W+ — dimmable, so you can run each zone independently.

What size extraction fan does the R240+ need?

A 200mm (8") extraction fan is the right fit for this tent volume. The Vivosun AeroZesh kit in the 8" size is our recommended setup — it includes the fan, carbon filter and ducting.

Is the R240+ light-proof?

Yes. The R240+ is built from robust, light-tight materials with no stray light leakage when closed, so your light schedule stays uninterrupted.
