HOMEbox Ambient R240+ Grow Tent 240x120x220cm | High PAR Reflective Indoor Grow Room

HOMEbox Ambient R240 Grow Tent | 240x120x200cm Multi-Light Indoor Grow Room Australia

The HOMEbox Ambient R240 is a 240x120x200cm indoor grow tent built for Australian growers running multi-light systems. At 4.0m2 of canopy space and a 22mm frame rated to 150kg, the R240 handles the structural demands of two or more high-intensity fixtures alongside carbon filters, inline fans, and a full irrigation system simultaneously. For growers scaling beyond a single tent to a dedicated high-yield growing space, the R240 provides the footprint, ventilation capacity, and structural integrity that multi-light indoor production requires.

Why Rectangular Footprint Matters for Multi-Light Growing

Running two lights in a square tent creates a coverage overlap in the centre and under-coverage in the corners. A 240x120cm rectangular footprint spaces two 120x120cm coverage zones side by side in a configuration that matches how dual-light systems actually perform, with each fixture covering its section of the canopy without central overlap or edge gaps.

The R240 supports two SANlight EVO 4-120 or EVO 5-120 fixtures positioned along the 240cm length, creating uniform PPFD across the full 4.0m2 canopy. Two EVO 4-120 fixtures at 265W each draw 530W total and cover the R240 footprint more efficiently than any single-fixture alternative in the same wattage range.

Structural Capacity for Serious Equipment Loads

A fully equipped multi-light tent carries significant overhead weight. Two LED fixtures, a large carbon filter, two inline fans, and associated ducting can easily exceed 50 to 60kg of overhead load. The R240 150kg rated frame and reinforced corner connectors are built for this scale. Budget tents rated to 20 to 30kg are not, and frame failure under load is a common failure mode in multi-light setups that use undersized structures.

Ventilation for Multi-Light Heat Management

Two high-output fixtures in a 4.0m2 space generate a heat load that requires serious extraction capacity, particularly during Australian summer. The R240 includes four 100mm ports, two 200mm ports, two 250mm ports, two 300mm roof ports, and four 250mm OmniFlow passive vents, with support for inline fans up to 12-inch. This configuration supports independent extraction zones for each half of the tent, which improves temperature uniformity across the full length of the canopy.

Frequently Asked Questions

What lights are recommended for the HOMEbox R240? Two SANlight EVO 4-120 fixtures (530W combined) provide efficient full coverage across 240x120cm. Two SANlight EVO 5-120 fixtures (680W combined) suit CO2-supplemented high-intensity setups in the same footprint.

How many plants fit in the HOMEbox R240? Typically 8 to 16 plants depending on training method and grow style. The 240x120cm footprint and 200cm height suits SCROG, SOG, and large plant configurations. The rectangular shape works particularly well for single-canopy SCROG training across the full 4.0m2.

What inline fan setup does the R240 need? Two 6-inch inline fans, one serving each half of the tent, is a common configuration for dual-light R240 setups. Alternatively a single 8-inch or 10-inch fan with well-placed ducting can handle the full volume. Running fans on a climate controller maintains stable conditions through the light-off temperature drops that occur overnight.

Is the HOMEbox R240 suitable for hydroponic systems? Yes. The PAR+ lining, waterproof floor tray, and multiple irrigation ports make the R240 compatible with large DWC, NFT, and recirculating drip systems sized for the 4.0m2 footprint.
