Haze in the past year I've seen some breeders and seedbanks change to small/medium/high yield instead of g/m2. With differences in growing skill, nutrients, lighting, etc, and possible phenos it's impossible for a breeder to tell a grower what their yield will be. Their best option is to give relative yields compared to their other strains.
Check out Dr Greenthumb, he uses g/m2 based on growing with a Sea Of Green. The figures are probably what he got one time, not yields that average growers like us will get.
Strain : Yield g/m2
Bubba Kush : 250 - 350
Chumaluma : 300 - 400
Big Laughing : 350 - 450
Endless Sky : 400 - 500
Millennium Bud : 450 - 500

To give you an idea of how that looks: I've got a 24"
Big Laughing with a couple of weeks of flower left, it's in a 12" round bucket - slightly over 1 sq ft for the plant. You could squeeze 8-9 plants that size in a meter squared (a square meter is 10.7 square feet). It hasn't started to swell like the last couple did, hopefully it will. On the low side I'd say slightly over 2 ounces, probably 2.5, and if it swells 3 oz, cured. A liter, liter and a half, of trimmed cured bud. There are a few pictures on this thread.
