either: a.) throw out or b.) remove from female growing area ASAP (dont want seeds) as soon as you know its a male is best. If u can grow it somewhere else and harvest it just before the flowers open, I have read that they can have quite a nice amount of THC
Welcome to grasscity... As the plant grows..pay CLOSE attention to about the fourth-seventh node...watch for one pollensack on a very thin vine...use a microscope lens or high power magnifying lens.. Can I assume that you wish to separate a male from a specific strain,,growing,,flowering,,obtaining viable pollen for breeding purposes..?
