actually the corn is for cow feed and they let it go longer than sweet corn. Even so, they will chop it long before the pot is finished. By that time I'll have to make sure the plants are trained away from the corn rows. As the cannabis are facing south it should be easy to do. Also, I'll have to keep them short to blend in with the brush as once the 12' corn stalks are gone they would be easy to see. I'll have to come up with something.
