Frequently Asked Questions
What size extraction fan does the CLOUDLAB 899 need?
The tent holds roughly 11.5 cubic metres (about 407 cubic feet) of air. As a general rule for grow tents, aim to exchange that full volume every 1-3 minutes, then size up to cover losses through your carbon filter and ducting. The 899 has four 8" and four 4" ducting ports built in, so an 8" inline fan is the natural fit for the main extraction.
How many grow lights can I hang in the CLOUDLAB 899?
The frame is rated to 113kg (250lbs) at each intersecting beam point, and the tent includes 16 hanging bars (8 standard plus 8 extra). Most full-spectrum LED fixtures in the 600-1000W range weigh far less than that per point, so two to four lights across the 8ft x 8ft footprint is realistic without stressing the frame.
What's the difference between the CLOUDLAB 899 and the CLOUDLAB 894?
The 894 is 8ft x 4ft (244 x 122 x 203cm), a long, narrow tent. The 899 is 8ft x 8ft (240 x 240 x 200cm), twice the floor area and a square layout. Both share the same 22mm steel frame, 2000D Oxford canvas and diamond mylar lining. The 899 simply gives you a full 8x8 room with extra duct ports to match.
Does the CLOUDLAB 899 come with a floor tray and tool storage?
Yes. It includes a heavy-duty floor tray to protect the floor from spills and runoff, plus a detachable tool bag for keeping pH pens, clips and other accessories inside the tent rather than on the floor outside it.
How thick are the poles and how much weight can the frame take?
The frame uses 22mm steel poles, thicker than the 16-18mm poles on standard hobby tents, with reinforced corners for extra rigidity. Beam capacity is up to 113kg (250lbs) at each point where poles intersect, enough to carry lighting, filters and fans without the roof sagging.
How many plants fit in a CLOUDLAB 899?
AC Infinity rate the 899 for up to 16 plants in 5-gallon (about 19L) pots. Plant count depends on your training style and veg time, so many growers run fewer, larger plants across the 64 sq ft floor.
Beschreibung
AC Infinity CLOUDLAB 899 Grow Tent (240 x 240 x 200cm / 8ft x 8ft) is a full square room for growers who want serious floor space without going to a long, narrow layout. At 64 sq ft it takes a multi-light setup comfortably, on the same heavy-duty CLOUDLAB frame as the rest of the range.
Built Like a Tank (Not Like Most Tents)
- 2000D Oxford canvas with a 500G light-proof layer underneath, thicker than standard tents for better insulation and zero light leaks
- 22mm steel poles, stronger than the typical 16-18mm frames, and doing more work over an 8ft span
- 250 lb (113kg) beam capacity at intersecting points, so lights, filters and fans hang without the roof sagging
- 16 hanging bars (8 standard + 8 extra included) for plenty of mounting points across the full room
- Reinforced corners + heavy-duty floor tray, built for long-term use rather than a single season
Maximum Light Efficiency = Better Growth
- Reengineered diamond Mylar interior, lab-tested for reflectivity
- Boosts light intensity and improves canopy penetration across a wide footprint
- More wall area means more light is either reflected back onto the canopy or lost, so the lining matters more in an 8x8 than a 4x4
Ventilation for a Bigger Room
- 4x 8" ducting ports and 4x 4" ports, enough for a serious extraction fan and intake
- Rear and side intake holes, 15 x 35cm each
- Extra duct ports for humidifiers, heaters or air conditioners without compromising the seal
- Double-cinching duct port design seals around the fan or filter in either direction
64 sq ft moves a lot more air than a 4x4, so don't undersize the extraction. Our Cloudline Pro T8 Fan & 69 Pro Controller Combo is sized to match this tent's 8" ports.
Zero Light Leaks, Proper Climate Control
- Front zipper flaps for added light-proofing
- High-performance SBS zippers on a large 35 x 100cm observation window
- Dual side doors for access from both sides
- Fully sealed environment for stable temperature and humidity
Smart Layout for Modern Growers
- Integrated controller mounting plate with a lightproof cable passthrough
- Multiple duct ports for fans, filters, heaters, humidifiers and AC units
- Detachable tool bag included

Who Is This Tent For?
The CLOUDLAB 899 suits growers who:
- Have outgrown a 5x5 and want one big square room instead of two tents
- Are planning a multi-light setup rather than one fixture stretched over too much floor
- Want a frame that can carry several lights, filters and fans without flexing
- Need proper extraction with 8" ports rather than adapting a small fan to a big room
What to Pair It With
Humidity control matters more as the room gets bigger. The HYDRONE 7 Dehumidifier is rated up to 10x10 grow tents. Comparing sizes? Have a look at the CLOUDLAB 894 (8ft x 4ft) or the CLOUDLAB 816 (10ft x 5ft). See the full range in our AC Infinity collection or browse all grow tents.
If you're building a proper 8x8 room, this is a frame that will still be standing grow after grow.
