GROW TENT

Homebox Ambient AR 300+: the 4.5 m² rectangular grow tent for demanding indoor growing

Give your plants a true indoor growing workshop. Measuring 300 × 150 × 220 cm, the Homebox Ambient AR 300+ unfolds 4.5 m² of floor space and nearly 9.9 m³ of volume in a rectangular format designed to sit neatly along a wall. PAR+ lining, reinforced steel frame and flawless black-out: every detail is engineered for dense, consistent harvests by the BloomLED experts, a growshop designed in France for more than 10 years.

Built for growers ready to step up, the AR 300+ welcomes both a SOG of several small plants and a handful of imposing specimens. Its 3-metre length makes it easy to organise distinct zones — mother plants, clones, vegetative growth — within a single controlled space, while the 1.50 m depth stays compact enough to fit into most interiors without taking over the whole room.

📐 Rectangular 300 × 150 cm format

The AR 300+ rectangular footprint fits where a square tent cannot: along a basement wall, in a narrow garage or a utility room. You line up your plants across 3 metres of length, improve airflow circulation and make the most of an often-wasted space, while keeping a 1.50 m depth that stays fully accessible from both sides.

✨ High-reflectivity PAR+ lining

The interior PAR+ coating bounces useful light back toward your plants instead of letting it scatter into the walls. You gain PPFD at canopy level and extract the most from every installed watt, for a denser, more even flowering and higher yields at equal lighting power.

🔩 Reinforced Ø 22 mm steel frame

The Ø 22 mm steel tube frame and its reinforced connectors carry 150 to 200 kg of equipment. Hang several LED panels, reflectors, a carbon filter and an extractor without worry: the tent stays stable, square and silent over time, even through intensive production cycles.

🌱 Generous 220 cm height

The 220 cm height frees the space needed above the canopy to hang powerful LED lighting, a carbon filter and an extractor without sacrificing plant growth. This headroom promotes even air mixing, limits hot spots and allows large specimens at the end of flowering.

🌑 Total black-out closure

The premium velcro-free black-out zips guarantee absolute darkness during the night phase. No light leak disturbs the photoperiod or stresses your plants — an essential point in flowering to avoid re-vegetation and preserve the quality of your harvest.

🌬️ Modular ventilation and waterproof tray

Multiple vent socks (Ø 100 to 350 mm) let you route air intake, extraction and duct passages exactly as you wish, to size an air exchange worthy of 9.9 m³. The removable, waterproof floor tray protects your room from splashes and wipes clean in seconds.

How much growing surface does the Homebox AR 300+ offer?

The AR 300+ measures 300 × 150 × 220 cm, that is 4.5 m² of floor space and about 9.9 m³ of volume. Its rectangular format lets you line up plants across 3 metres and is ideal for an installation along a wall or in a long, narrow room.

Which LED lighting should I choose for this tent?

To cover 4.5 m² evenly, plan for around 2000 to 2400 W of horticultural LED, spread across several full-spectrum panels rather than a single source. This distribution ensures consistent PPFD along the whole length and takes full advantage of the PAR+ lining.

What is the difference between the AR and AQ Homebox models?

AR models are rectangular (here 300 × 150 cm) while AQ models are square (for example 240 × 240 cm). The AR format is ideal against a wall or in a narrow space, whereas the AQ favours a compact, centred footprint. Both share the PAR+ lining and the steel frame.

Can it hold a carbon filter and an extractor?

Yes. With a 150 to 200 kg load capacity and numerous duct passages, the AR 300+ easily houses a carbon filter, an extractor and an intake fan in addition to the lighting. The 220 cm height leaves the room needed above the plants for this equipment.

Is the AR 300+ suitable for beginner growers?

Absolutely. Delivered with an assembly guide, colour-coded connectors and a waterproof floor tray, it assembles tool-free in under an hour. Its large volume forgives the small early climate mistakes, and the BloomLED team stays available to advise you on the complete setup.

The rectangular 300 × 150 cm format of the AR 300+ turns a plain garage, basement or utility-room wall into a real indoor growing workshop — without ever sacrificing height, sturdiness or HomeBox black-out quality.
