How much does a 4x4 grow tent (4ft x 4ft, 16 sq ft) yield? An intermediate grower running a 500W LED in coco coir can expect roughly 240–360 grams (8–13 oz) of dried flower per harvest. A 4x4 tent fits about 2-8 plants and costs around $26-39/month to light. Pair it with a 450–550W LED (e.g. Spider Farmer SF4000). Adjust the calculator for your exact light, medium, and experience level. Running one: 104 cu ft at the standard 6.5ft tent height, 31W per square foot, drawing about 4.2A on a 120V circuit and needing roughly 130 CFM of extraction with a carbon filter — a 6-inch inline fan. Where it fits: A spare room corner or garage bay. Most grow gear, tutorials and light coverage charts are written around this footprint. What it is for: The default single-tent grow: four plants in 5-gallon pots, or two heavily trained plants under a SCROG net. How to train it: SCROG with two to four plants gives the most even canopy; SOG with nine or more shortens veg time. What limits you first: Canopy evenness — the corners run dimmer than the centre unless you train flat.
A 4x4 grow tent (16 sq ft) under a 500W LED typically yields 240–360g (8–13 oz) of dried flower for an intermediate grower in coco coir. Beginners average less; experts more.
A 4x4 tent comfortably fits 2-8 plants in 3–5 gallon pots. 4 is a common sweet spot; use SOG for more smaller plants or SCROG for fewer larger ones.
Aim for about 500W of quality LED for a 4x4 tent — roughly 31W per square foot. A good match is a 450–550W LED (e.g. Spider Farmer SF4000).
Running a 500W LED 18 hours a day at ~$0.12/kWh costs about $26-39 per month. Flowering at 12/12 lowers this.
A 4x4 tent is about 104 cubic feet at the standard 6.5ft height. Target one full air exchange per minute plus roughly 25% for carbon filter drag — about 130 CFM, which is a 6-inch inline fan.
A spare room corner or garage bay. Most grow gear, tutorials and light coverage charts are written around this footprint. The default single-tent grow: four plants in 5-gallon pots, or two heavily trained plants under a SCROG net. The constraint that bites first at this size: canopy evenness — the corners run dimmer than the centre unless you train flat.
