HOMEbox Ambient R120 Grow Tent 120x90x180cm | Optimised for 600W HID & LED Australia

The 120x90 Rectangular Grow Tent Built for 600W HID and LED Setups

A square tent and a rectangular reflector don't share the same footprint. Run a 600W HPS with a standard rectangular reflector in a square tent and you end up with uneven light spread, dark corners, and heat building up in places your canopy doesn't need it.

The HOMEbox Ambient R120 is built to match that geometry properly. A heavy-duty 120x90x180cm rectangular grow tent with PAR+ super reflective lining, a 22mm reinforced steel frame rated to 75kg, and a multi-port ventilation system built for independent reflector cooling and full tent airflow control. If you're running a 600W HPS with a rectangular reflector, or an LED fixture sized for the same footprint, this tent's shape is doing real work for you rather than against you.

Why the Rectangular Footprint Matters

• Rectangular geometry (120x90cm). Matches the light footprint of a 600W HID with a rectangular reflector, reducing the hotspots and dark corners a square tent creates with the same fixture.
• PAR+ super reflective interior. Directs more usable photons back into the canopy across the full 1.08m² growing area.
• Dual 160mm air-cooled lighting ports. Two dedicated 160mm ports allow independent reflector ventilation, keeping your lamp cool without disrupting tent climate.
• Heavy-duty 22mm steel frame. Rated to 75kg, handles a full lighting rig, carbon filter, and inline fan without flex.
• Full lightproof seal. No velcro gaps or light leaks, fully sealed for photoperiod-sensitive plants through the dark cycle.
• Double side access. Two large access points for plant management, training, and harvest without disrupting the environment.
• Removable waterproof floor tray. Catches runoff and spills.
• German-engineered build quality. Plant-safe materials, reinforced corners, and long-life canvas construction.

Frequently Asked Questions

What size grow tent do I need?

The HOMEbox Ambient R120 gives you 1.08m² of growing space at 120x90cm. As a general guide, a 60x60cm tent suits 1 to 2 plants, this 120x90cm size suits 4 to 6 plants in a SOG setup, and larger tents allow for bigger yields or multi-tier growing. Choose based on your available space, the number of plants you plan to grow, and the height required for your lighting.

Is the R120 compatible with my grow light and fan?

The R120 has 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 R120 to assemble?

The R120 includes a full steel frame with tool-free push-fit connectors and a full-coverage zip-on canvas. Most growers complete assembly in 20 to 30 minutes. Poles are colour-coded and instructions are included in the box.

How do I clean and maintain the R120?

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 R120 ship fast within Australia?

Yes, the R120 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.
