Regular cannabis seeds are grown from a male and a female plant and can also produce both genders themselves. The odds of getting a male seed and a female seed are about even with regular seeds (50% chance to get a female plant and 50% change to get a male plant). You can’t tell by the look of the seed whether it’ll produce a male or female plant, you’ll only know once it’s started blooming. After about two weeks in to the blooming period you’ll be able to tell if your plant is male or female. Male plants have oval-shaped tips and female plants produce drop-shaped calyxes.
