The Homebox Ambient AQ 120+ grow tent is the go-to reference for demanding indoor growers. Designed in Germany by HomeBox, this premium tent combines 1.44 m² of usable floor space with an exceptional 220 cm height — that's 20 cm taller than the standard AQ120. You get the room you need to grow tall genetics, stack a hydro system on a riser, or simply pull your grow light further from the canopy without sacrificing PPFD.

The extra 20 cm over a standard AQ120 makes a real difference: your grow light stays at a safe distance even in full bloom, you avoid heat stress on the canopy, and you have room for an elevated hydro system or a high SCROG net.
The diamond-pattern Mylar interior bounces 95% of your LED or HPS light back onto the canopy without hot spots. PPFD is distributed more evenly across the entire footprint — the result is homogeneous growth and stronger edge-to-edge yields.
Ø22 mm steel poles and HomeBox's reinforced corner connectors safely support up to 35 kg from the ceiling. Easily suspend a 400 W LED bar, an inline fan and a carbon filter without the frame flexing.
Two Ø150 mm sleeves for intake/extraction, plus two Ø100 mm sleeves for cabling. All come with cinch straps and lightproof socks — your photoperiod stays sealed.
The exterior 600D polyester is fully UV-resistant and lightproof. It also helps contain odours and keeps pests out, so your day/night cycle remains stable — essential when flipping to flower without stressing the plants.
The included waterproof tray slides out and rinses clean in seconds. No more stained floors or unhappy neighbours after a drip system overflow.
Over 1.44 m², aim for 350-450 W of real LED draw for bloom. A 400 W full-spectrum quantum board or LED bar fixture covers the footprint perfectly and the 220 cm height gives plenty of thermal margin. For veg only, 200-250 W is enough.
Which extractor fan should I run in this 120×120 tent?Interior volume is about 3.17 m³. For one full air exchange every 1-2 minutes (recommended in flower), use a Ø150 mm extractor rated 350-400 m³/h, paired with a Ø150 carbon filter for odour control. The AQ 120+ vent sleeves are sized for it.
What's the difference vs. the standard AQ120?The AQ 120+ adds 20 cm of vertical clearance (220 vs. 200 cm). Decisive if you run tall genetics, an HPS lamp that needs distance, or any system that elevates the pots. The standard AQ120 stays excellent for shorter setups.
Is assembly hard for beginners?Not at all. The HomeBox system clips together in 20-30 minutes without tools. Poles are numbered and an illustrated manual is included. No prior experience required.
How many 15 L pots fit inside?The AQ 120+ comfortably holds 4-6 pots of 15 L in classic bloom, or up to 9 smaller (7 L) pots in SCROG. The 1.44 m² footprint also accommodates a 4-site hydro/aero rig.
The Homebox Ambient AQ 120+ is our pick for growers who want a durable, XL-height, top-finish indoor grow tent. Curated and shipped by BloomLED, France's horticultural lighting expert for 10+ years.
