Environmental crossover[ɪnˌvaɪərənˈmɛntl ˈkrɒsˌəʊvə]
Environmental crossover occurs when a specific cultivation substance reaches another field. This crossover is not controlled and often leads to adverse outcomes.
Because pesticides and pollen are so easily transported via the air, they are the leading causes of environmental crossover. This environmental crossover can readily occur if it is a windier day and pesticides have recently been applied.
Indoor growers may avoid environmental crossover because they control the growing environment, even regulating the light and dark cycles.
