Theses numbers you see are with perfect/optimal growing conditions. Having the strain dialed into your grow setup. An indoors the weight is for a Square meter not single plant. That is the yield you can achieve if everything is perfect environment for that strain in a 10-11 sq. foot grow area. Keep in mind that theses breeders have they own growing skills down pack with their strains. Out doors you could pull a lb. maybe 2 off 1 plant.
You will have to do massive training and a really long veg. to pull a lb off 1 plant imo. And after the time you are gonna spend you will be more efficent running a 8 week perpetual harvest. As you should start thinking the time you spend vegging and then flowering just to get a elbow from 1 plant it would be cheaper and more efficient to run multiple
