Pairs well with
The CLOUDLAB 642 is AC Infinity's 4x2 grow tent — 120 x 60 x 180cm of sealed, climate-controlled growing space in a footprint that tucks into a bedroom corner, garage bay, or basement alcove. 2000D oxford canvas backed by a 500G lightproof layer, 22mm steel poles rated to 113kg, reengineered diamond mylar lining, and an integrated controller mounting plate with a lightproof cable passthrough. Assemble it once and it stays put for years.
Specifications
- AC Infinity rates this tent at 2 plants in 19L (5 gallon) pots. Drop to smaller containers and you will comfortably fit 3 to 4 — the rating is about pot footprint, not the tent's limits
- The 120 x 60cm footprint is the narrow one. It suits a wall run, a closet, or a spare-room corner where a square 120 x 120 tent simply will not fit
- 180cm internal height is workable for a full cycle but tight in late flower with tall varieties. Plan on topping, LST, or a SCROG net before you start, not after
- Need more room? The CLOUDLAB 894 steps up to 240 x 120 x 200cm with 8 hanging bars and an 18-plant rating
- Running an AC Infinity controller? The built-in mounting plate makes this the natural tent for it — no external brackets, no cable clutter
Setting Up Your CLOUDLAB 642
Pairs Well With
A 4-inch fan handles this volume cleanly on a modest light. Step to 6-inch if you are running higher wattage or fighting summer heat — there are four ports of each size.
Carbon FiltersNot optional in a sealed tent. Match the filter diameter to your inline fan and you have a complete extraction loop that actually controls odour.
LED Grow LightsA 120 x 60cm canopy pairs well with a 200-250W quality LED. The 3 hanging bars let you position it evenly across the length of the footprint.
Environment ControllersThe mounting plate on this tent is built for AC Infinity controllers — automate VPD, fan speed, and temperature without extra hardware or cable mess.
Frequently Asked Questions
Can I fit 4 plants in the CLOUDLAB 642?
Yes, in smaller pots. AC Infinity's official rating is 2 plants in 19L (5 gallon) containers, which is the honest figure for full-size plants with proper canopy spread. Drop to 11L pots or run a SOG-style setup with smaller containers and 3 to 4 plants fits the 120 x 60cm footprint comfortably. The constraint is pot diameter, not the tent.
Do I need a 6-inch inline fan for this tent?
No, not usually. A 4-inch inline fan is the right match for a 120 x 60 x 180cm space running a moderate light. Step up to 6-inch if you are pushing a high-wattage fixture, running warm ambient temperatures, or supplementing CO2. The tent gives you four ports of each size, so you can change your mind later without buying a new tent.
Can I run a full veg and flower cycle at 180cm height?
Yes. 180cm handles most varieties through a complete cycle once you account for pot height and light hanging distance. Budget roughly 30cm for the pot and 30-40cm for the light, which leaves you a workable canopy zone. Tall or heavy-stretching varieties will get tight in the last few weeks — topping, LST, or a SCROG net solves it if you plan for it early.
Is 2000D canvas actually better than cheaper tents?
Yes. The denier rating reflects the density of the canvas weave, and 2000D is substantially thicker and more tear-resistant than the 600D or 1680D used in budget and mid-range tents. On the CLOUDLAB it is paired with a separate 500G lightproof layer and front zipper flaps, so light control does not depend on the canvas alone. It also holds up better to the structural stress of heavy hanging gear over multiple grows.
Can I mount an AC Infinity controller directly to this tent?
Yes. The CLOUDLAB 642 has an integrated controller mounting plate on the frame with a lightproof cable passthrough beside it. Your controller sits outside the canopy away from humidity, and the sensor and power cables run through the passthrough without breaking the light seal. No brackets, adhesive mounts, or taped-over cable holes required.
Does the 2-year warranty cover the canvas, poles, and zippers?
Yes. AC Infinity's 2-year warranty covers manufacturing defects across the full tent — canvas, steel poles, corner fittings, and zippers. It does not cover damage from misuse, overloading the frame beyond the 113kg rating, or normal wear from repeated assembly and disassembly.
