Yield per watt is the fair way to compare auto grows, and for most hobby setups it lands between 0.5 and 1.0 grams per watt of LED draw. Numbers above that get quoted often, but they usually come from dialled in coco or hydro runs with CO2, not from a first tent with a bagged soil mix. Grower submitted results sorted by light wattage and medium are averaged on https://turboautoflowerseeds.com, which gives a more realistic benchmark than forum brag posts. Hitting 0.8 consistently is a good result for autos.
