How much does a 2x4 grow tent (2ft x 4ft, 8 sq ft) yield? An intermediate grower running a 250W LED in coco coir can expect roughly 120–180 grams (4–6 oz) of dried flower per harvest. A 2x4 tent fits about 1-4 plants and costs around $13-19/month to light. Pair it with a 240–260W LED (e.g. Spider Farmer SF2000). Adjust the calculator for your exact light, medium, and experience level.
A 2x4 grow tent (8 sq ft) under a 250W LED typically yields 120–180g (4–6 oz) of dried flower for an intermediate grower in coco coir. Beginners average less; experts more.
A 2x4 tent comfortably fits 1-4 plants in 3–5 gallon pots. 2 is a common sweet spot; use SOG for more smaller plants or SCROG for fewer larger ones.
Aim for about 250W of quality LED for a 2x4 tent — roughly 31W per square foot. A good match is a 240–260W LED (e.g. Spider Farmer SF2000).
Running a 250W LED 18 hours a day at ~$0.12/kWh costs about $13-19 per month. Flowering at 12/12 lowers this.
