Finding Your Current Scenario's Average Crop Yield
Generally speaking, crops-as-usual can have yields that vary +/-15% from the average, so don't expect them to be nearly identical. However, this figure is just a rule-of-thumb. Crops can fluctuate more, especially over the course of a full year when seasons bring unwanted, and sometimes uncontrollable, changes to the indoor environment. Temperature, humidity, and water quality to name a few. For most growers, 3 to 5 crops is sufficient for a workable average.
