In a space ogf 3ft by 2ft you would get 4 plants in no prob if you are only vegging for a week .You can look up one of mobays threads in which he done a plant from seed with only 1 week veg .I think that he yeilded aboyut 33 gram from a white russian,If you find that thread then you will see the space that a plant vegged for a week will take but imo you would get 4 easy in that space. be safe the postman.
