How can I determine if it’s a male or a female? And why do people prefer females over males?
This is easily the most frequently asked question about marijuana. Marijuana is strange among annual plants because it comes in male and female varieties. Growers (and smokers) are particularly fond of ripened, unfertilized female cannabis buds that can only achieve this state if the males are removed.
Females react to this lack of pollination by producing more flowers which will “ripen” eventually. What actually happens is that the pistil will recede into the ovary to form a false seed pod. Seeing as how they have not been fertilized, these females have no seeds and are referred to as “sinsemilla,” (Spanish for “without seed”).
If you know what you’re looking for, male marijuana plants can be differentiated quite easily from the females. Males grow small rounded buds that open in clusters of yellow or white flowers. By contrast, the female flower has only several pairs of pistils jutting out from the ovary. In general, male and female flowers will appear on separate plants. If one plant produces both male and female marijuana buds, then they’re referred to as hermaphrodites. For the most part, these plants are disregarded, but they can have some effectiveness in breeding.
