I calculated that based on 9 square feet per plant, you could fit 4900 on an acre. If you assumed something less, say 4000 per acre, it would take 75 acres of land to grow 300,000 plants. In farming that would be completely feasible.. What seems a little odd is that the Green House people weren't aware someone had purchased that many of their seeds.. One wouldn't think that would go unnoticed and I doubt that they were in "breeders packs." Just sayin'
