Estimate your cannabis harvest in seconds. Set your grow space, LED wattage, plant count, grow medium, and experience level to get a yield range in grams and ounces, the optimal number of plants, cycle time, and estimated monthly electricity cost. For harvest timing use the cannabis harvest calculator, and for running costs use the grow room cost calculator. See expected yield broken down by grow tent size below.
Yield per plant depends on grow space, light wattage, medium, and strain. A 4x4 tent under 400W LED averages 1.5–3 oz per plant in soil, or 2–4 oz in coco. Use the calculator to estimate your exact setup.
A yield calculator gives a realistic range based on grams-per-watt, light efficiency, and plant density. Actual results vary with strain, training, and environment, but the estimate is a reliable planning baseline.
