What Fits in a 5x5 AC Infinity Build
The 5x5 is the next step up from 4x4 in usable canopy, fitting 6 plants comfortably with full-canopy lighting coverage. The
AC Infinity 5x5 lineup is well-supported with three SKU paths: tent-only Cloudlab 866, tent + ventilation kit, or the complete Advance Pro 6-plant kit with the Wi-Fi Smart Controller bundled.

Spec Targets for a 5x5
For a 6-plant 5x5 grow, target 400W of full-spectrum LED at the canopy. The Ionboard S44 at 400W in the Advance Pro kit covers the full 5x5 footprint at 12-15 inches hang distance with PPFD in the 700-900 range, which is the sweet spot for veg and standard flowering. For more aggressive flowering yields, the Ionframe EVO6 at 500W is the upgrade path with better edge uniformity at the corners. A 6-inch Cloudline T6 at 50 percent duty cycle delivers the airflow needed.

Frequently Asked Questions
How many plants fit in a 5x5?
Six plants at standard 18-inch spacing or four large plants with heavy training. Six is the kit-supported count for the Advance Pro 6-plant kit, giving each plant roughly 1.5x1.5 of personal canopy.
What light wattage for a 5x5 AC Infinity tent?
400W of full-spectrum LED is the right size. The Ionboard S44 at 400W is the kit default. For aggressive flowering or premium yields, step up to the Ionframe EVO6 at 500W, which has better edge-to-edge uniformity in a 5x5.
Cloudlab 866 vs Advance Pro 6-plant kit?
The Cloudlab 866 is the tent on its own. The Advance Pro 6-Plant Kit ships the same tent plus an Ionboard S44 LED, Cloudline T6 fan, carbon filter, ducting, and Smart Controller 69 Pro Plus. The Pro tier kit gives you Wi-Fi and a sensor probe for closed-loop control out of the box.
What CFM fan for a 5x5?
A 6-inch Cloudline T6 at 402 CFM is the right size. Running at 50 percent duty cycle gives roughly 200 CFM through the carbon filter, which is the right air-exchange rate for a 5x5 with 6 mature plants. Step up to a T8 only if you're running very high-power lighting and need extra cooling headroom.
Does the Pro kit's Ionboard S44 cover the full canopy?
Yes, the S44 at 400W spreads PPFD across the full 5x5 at 12-15 inches hang distance, with edge falloff of about 20-25 percent. That's acceptable for veg and standard flowering. If chasing maximum yields with even canopy intensity, the Ionframe EVO6 with deeper-set diodes gives tighter edge PPFD.
Can I run a 5x5 with one 6" Cloudline?
Yes, one 6-inch Cloudline T6 handles a 5x5 grow at moderate duty cycles. The tent volume (~165 cubic feet) divided by the T6's 402 CFM gives roughly 2.4 air exchanges per minute, which is the right margin for cooler running temps and steady RH. Add a clip-on circulation fan for canopy-level air movement.
