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

The 240x120 Large-Format Grow Tent Built for Multi-Light Systems and Maximum Yield

Scaling an indoor grow introduces two performance challenges most tents aren't built to handle: heat accumulation and uneven light distribution. Run two or three high-intensity lights in a poorly designed space and you're fighting hotspots, dead zones, and a climate working against you at every stage of flower.

The HOMEbox Ambient R240 is built to handle both. A professional-grade 240x120x200cm grow tent with PAR+ super reflective lining, a 22mm reinforced steel frame rated to 150kg, and a high-volume ventilation system designed for independent reflector cooling and full climate control across a 4.0m² canopy. Across 2 to 3x 600W HID, 2x 1000W HID, or a multi-bar LED array, this tent is built to handle the load and extract every usable photon from it.

Why the R240 Suits Multi-Light Setups

• Large rectangular footprint (240x120cm). Delivers consistent PPFD distribution across the full 4.0m² canopy, reducing the hotspots and dark corners that cost you at harvest.
• PAR+ super reflective interior. Increases usable light across the entire grow area, reducing wasted energy and excess radiant heat without adding wattage.
• Multi-light compatibility. Engineered to support 2-3x 600W HID systems or 2x 1000W HID systems (air-cooled recommended), with dedicated high-volume ports for independent reflector ventilation.
• Heavy-duty 22mm steel frame. Rated to 150kg, handles multiple lighting rigs, carbon filters, and inline fans without flex or structural compromise.
• Full lightproof seal. No velcro gaps, no light leaks, fully sealed to protect photoperiod-sensitive plants through the dark cycle.
• Double side access. Two large access points for canopy management, training, and harvesting across the full 240cm width.
• German-engineered build quality. Plant-safe materials, reinforced corners, and long-life canvas construction built for years of high-output use.

Frequently Asked Questions

What size grow tent do I need?

The HOMEbox Ambient R240 gives you 4.0m² of growing space at 240x120cm. As a general guide, a 60x60cm tent suits 1 to 2 plants, 120x120cm suits 4 to 6 plants in a SOG setup, and a 240x120cm footprint like this one typically suits 8 to 16 plants or a full multi-light SCROG canopy. Choose based on your available space, plant count, and the number of lights you plan to run.

Is the R240 compatible with my grow light and fan?

The R240 features multiple ducting ports in standard sizes to fit most inline fans and carbon filter setups, with fabric-sealed cable entry ports for lights on the top and sides. It's compatible with LED grow lights, HPS/MH fixtures, and T5 fluorescents. Check your light's footprint against the tent's internal dimensions before purchasing.

How difficult is the R240 to assemble?

The R240 includes a full steel frame with tool-free push-fit connectors and a full-coverage zip-on canvas. Most growers complete assembly in 30 to 45 minutes given the larger size. Poles are colour-coded and instructions are included in the box.

How do I clean and maintain the R240?

Wipe down the interior reflective lining with a damp cloth between grows. Zip openings can be lubricated with a small amount of beeswax or candle wax if they become stiff. Avoid harsh chemicals on the reflective lining. Store folded when not in use to extend the fabric's lifespan.

Does the R240 ship fast within Australia?

Yes, the R240 ships from our Australian warehouse with fast tracked delivery to all states and territories. Most orders to VIC, NSW, QLD, SA, and ACT arrive within 2 to 5 business days. WA, NT, and TAS orders typically arrive within 5 to 12 business days.
