This is an impossible question to answer... it depends on far too many variables to count! What an expert grower can get out of a particular strain/plant, for example, will be WAY more than someone who is growing their very first seed of the same strain... different soils, different nutes, different lights, different techniques.... I've grown one autoflower that yielded 4.2oz ... another autoflower (different strain) only yielded .6 oz - seriously - just do your grow, harvest it, dry it and weigh it... that will give you your answer!
