4×8 Grow Tents — 12 to 16 Plants in a Versatile Footprint
The 4×8 grow tent is one of the most popular sizes in indoor growing — large enough for a productive harvest of 12–16 medium-to-large plants, yet compact enough to fit in a dedicated room without dominating the entire space. Its rectangular footprint makes it easy to work on plants from both long sides and fits naturally against a wall or in a corner while still allowing access for maintenance.
Lighting a 4×8 Grow Tent
A 4×8 footprint requires two fixtures for even canopy coverage — single-fixture coverage across a 32 sq ft canopy produces unacceptable intensity drop-off toward the edges. Two 600–800W LED fixtures, or two 600–1,000W HID fixtures, provide matched coverage across both halves of the tent. Qualified LED brands including Growers Choice, Gavita, AC Infinity, and Faven offer bar-style fixtures that work well in side-by-side configurations across the 8-foot length. Use our PPFD & Light Coverage Calculator to model your specific fixture placement and verify DLI targets across the full footprint.
Ventilation for a 4×8 Tent
A standard 4×8×7 ft tent contains approximately 224 cubic feet of volume. For complete air exchange once per minute, you need a minimum 224 CFM inline fan — add 30% for carbon filter resistance, making a 300+ CFM fan the practical minimum. Use our Ventilation & Carbon Filter Sizing Calculator for a precise CFM recommendation including your specific ducting configuration and filter type.
