Regular Seeds contain both male and female seeds, which allows for second and third generations of seeds, and is therefore a great choice for growers with a larger garden. Regular seeds usually contain 55% to 65% of female seeds. In order to make sinsemilla marijuana, the male and female plants need to be separated before flowering time. This requires knowledge of how to recognize the genders in order to separate them. The plant’s gender can be determined at the beginning of the flowering stage.
