AC Infinity 4x8 Grow Tent

A 4x8 (48 inch by 96 inch) footprint fits 6 to 8 plants at standard spacing. The double-square layout runs best with two LEDs side-by-side: either 2x 240W Ionboard S33 panels or one 500W Ionframe EVO6 plus a smaller supplemental. Ventilation pairs with a 6-inch or 8-inch inline fan moving 350 to 500 CFM through a matching carbon filter. Ceiling clearance for a 6-foot-8-inch Cloudlab 894 plus 12 inches of light hood plus 12 inches of inline fan adds to roughly 8 feet 8 inches of vertical room space. The core decision is one 4x8 with two lights vs two separate 4x4 tents with one light each.

AC Infinity 4x8 Grow Tent: Complete Guide

What Fits in a 4x8 AC Infinity Build

The 4x8 is a double-square footprint that gives the same total canopy as two 4x4 tents in one shell. The AC Infinity 4x8 lineup centers on the Cloudlab 894 (single-chamber 4x8) and the 4x8 ventilation kit. There's no Advance 4x8 kit in the lineup; users size their own light and controller around the tent.

Lighting Strategy: Two Lights vs One Big Light

The 4x8 has two viable LED layouts. Option one is two Ionboard S33 panels at 240W each, mounted side-by-side, which gives 4x4 coverage on each half. This is the cleaner pick because each panel hangs over its own 4x4 zone with no light-bleed concerns. Option two is one Ionframe EVO8 at 730W centered, which gives more uniform PPFD across the whole 4x8 but at higher upfront cost. For most home grows, the 2x S33 path is the better balance of cost, coverage, and flexibility.

Frequently Asked Questions

How many plants fit in a 4x8?
6-8 plants at standard 18-inch spacing, or 4 large plants with heavy training. For continuous harvests, run 4 plants per side and stagger veg/flower timing between the two halves.
Do I need one light or two for a 4x8?
Two Ionboard S33 panels (240W each) is the most common layout and gives clean 4x4 coverage on each half. One Ionframe EVO8 (730W) is the alternative if you want more uniform PPFD across the full 4x8 footprint, though at higher cost. Avoid running a single sub-500W light, edge PPFD drops too steeply.
What CFM fan for a 4x8 tent?
A 6-inch Cloudline T6 at 402 CFM works at higher duty cycles, but the cleaner pick is an 8-inch Cloudline T8 at 807 CFM running at 40-50 percent. The bigger fan keeps noise low while moving the air the larger volume needs.
Is a 4x8 better than two 4x4 tents?
A 4x8 is more space-efficient (one shell vs two) and shares one exhaust path. Two 4x4 tents give independent climate control for veg and flower on offset cycles. For continuous staggered harvests with separate climates, two 4x4s win. For one synchronized grow, the 4x8 is simpler.
What's the ceiling height for a 4x8?
Plan for 8 feet 8 inches minimum. The Cloudlab 894 is 6 feet 8 inches tall. Add 12 inches above for the inline fan and ducting, plus 12 inches inside for the LED at proper hang distance. Standard 9-foot ceilings fit comfortably; 8-foot ceilings work but require compact ducting.
Can I run veg in one half and flower in the other?
Not in the Cloudlab 894 (single-chamber). The 894 has one continuous interior with no built-in divider. For continuous-harvest staggering in a single tent shell, look at the smaller dual-chamber Cloudlab 864D (5x4) instead, or run two 4x4 tents on opposite cycles.
