2.4 x 2.4 x 2.2m Grow Tent — Ambient Q240+ by HOMEbox
The HOMEbox Ambient Q240+ is a 2.4 x 2.4 x 2.2m (8x8) grow tent with 5.76m² of grow space — the biggest square tent in the Ambient range short of the Q300+, sized for four full 1.2m lighting zones under one roof. German-designed with HOMEbox's PAR+ reflective inner lining, a 200kg load-rated frame — the highest in the range — extra-large side windows, zippered access on all sides, and Total-Blackout light-proof zippers, it's a grow room in everything but the renovation. 5.76m² Grow SpaceFour full 1.2m lighting zones — a serious canopy or a large perpetual rotation in a single tent. 200kg Load RatingThe highest rating in the Ambient range — four lights, a big fan and filter hang with margin to spare. Extra-Large Side WindowsOne-piece oversized windows improve access so much you can slide pots out without lifting them. PAR+ Reflective LiningHOMEbox's optimally reflective inner coating directs more plant-usable light back at your canopy. Total-Blackout ZippersLight-proof zippers seal the tent without covers or velcro — no stray light, no stressed plants. MicroMesh AirventsFour Ø350mm OmniFlow airvents with 700 micrometre insect mesh keep the big canopy breathing.

Our pick is four Treegers GL650W+ — 2,600W of dimmable full-spectrum coverage across the 5.76m², wound back for veg and run up in flower. Extraction at this volume wants a 250mm (10") fan. The SigilVentus 250mm Silenced Fan is our rec — near-silent EC motor, smart-controller ready — ducted out a Ø300mm side port with a matching 250mm carbon filter. All ducting ports are side-mounted on this model — hang the fan and filter from the roof bars and run ducting out a side Ø300mm port. It ships in two packages, so clear some floor space before assembly day. Setting Up Your Q240+ 1Clear a level 2.4 x 2.4m floor space with at least 2.2m of ceiling clearance, plus room to walk the perimeter — you'll use every access panel. Assemble the Ø22mm frame, no tools needed. 2Pull the canvas over the frame from the top down — definitely a two-person job at this size — and zip it closed with even tension so the corners seat properly. 3Hang a light over each 1.2m zone, then mount your fan and carbon filter from the roof bars, ducting out a Ø300mm side port. 4Open OmniFlow airvents on opposite sides for cross-flow passive intake, cinch unused ports closed, and check for light leaks with the lights on and room lights off. 5Dial in your environment before plants go in. Nearly six square metres holds a lot of air — check temperature and humidity at canopy height in all four corners, not just the middle. Pairs Well With Treegers GL650W+ LEDOur recommended light for the Q240+ — run four, one over each 1.2m zone. SigilVentus 250mm Silenced FanNear-silent EC extraction in the 250mm size this tent volume needs — smart-controller ready. SigilVentus Carbon FiltersMatch the 250mm filter to the silenced fan for a complete odour-controlled exhaust line. NutrientsBase nutrients and additives to feed nearly six square metres of canopy. Frequently Asked Questions Is the HOMEbox Ambient Q240+ an 8x8 grow tent?Yes. At 240 x 240cm the Q240+ is the metric equivalent of an 8x8 (8ft x 8ft) grow tent, with 5.76m² of grow space and a 2.2m height. Will the Q240+ fit under a standard Australian ceiling?Yes. Standard Australian ceilings are 2.4m, leaving around 20cm of clearance above the 2.2m tent — enough to assemble it in place. Check your ceiling height first if the room has bulkheads, downlights or a lower ceiling. What lighting suits the Q240+?Four LEDs, one per 1.2m zone, suit the 5.76m² grow area. Our light of choice is four Treegers GL650W+ — dimmable, so you can wind each zone back for veg and run it up in flower. What size extraction fan does the Q240+ need?A 250mm (10") extraction fan suits this tent volume. The SigilVentus 250mm Silenced Fan is our recommended setup — quiet EC motor, smart-controller compatible, ducted out a Ø300mm side port with a matching 250mm carbon filter. How much weight can the Q240+ frame hold?Up to 200kg — the highest load rating in the Ambient range. Four lights, a 250mm fan, a carbon filter and hanging accessories all fit within it comfortably. How does the Q240+ ship?In two packages — the frame and canvas are split for manageable handling. Both boxes arrive together as one order. Is the Q240+ light-proof?Yes. The Q240+ uses Total-Blackout light-proof zippers and robust light-tight materials, so the tent seals completely without covers or velcro flaps.
