maybe you just read my last reply wrong , I never said that the color would be used to identify the plants , I just said if the color is green and not in the designated location it is plucked.
maybe I wasnt to clear about that part.
I myself have planted seeds and have noticed how they for the most part shoot straight up after the sprouts leave the seed.
possibly veering no more than 1/8 inch further from where they are planted...depending on the seed size.
unless there are rocks or some other obstacle in there way.
which pretty much covers your reply.
listen I understand how something such as this would threaten
your job , so I dont blame you for securing your future.
after all , why would farmers need biologist if they grew there own seed , or were capable of growing there own seed as is the norm these days because of biologist fixing seeds so that they cant.
