it depends not on just the strain, but the light nutrients etc....too few watts from your light, and the buds wont be compact...too little nutrients or too much nutrients can both hurt yield...also temp and CO2 levels, what youre feeding them etc...ive seen 31oz plants on here, and 10 gram plants...ive read Pure Power Plant produces some big plants, and ive read many seed descriptions saying 500+grams per m^2, so i dunno.
