Male Harvest
Harvest male plants before they disperse pollen. Most growers remove them from the garden as soon as they are spotted at pre-flowering, near the end of vegetative growth. Male flowers produce visible pollen sacks with viable pollen 2-4 weeks after lights are set to a 12-hour day/night photoperiod.
Put a plastic bag over any male plants that might disperse pollen before cutting the main trunk off at the base. Shake the plant as little as possible to minimize any pollen dissemination.
