This article is going to show you how to tell the difference between male and female cannabis plants to properly sex them. In particular, I want to show you how we determine the sex of our cannabis plants while they are still quite young. It gets significantly more obvious as the plants begin to mature and flower. On the other hand, it can be a bit more tricky to sex cannabis plants in the early pre-flower phase , but it is definitely possible! As a disclaimer, this article is intended for those who can legally grow cannabis at home. In all of our years growing, we have never had a cannabis plant grown from feminized seed turn out to be a male — though we only grow a handful of plants per year.
Sexing Cannabis: How to Tell the Difference Between Young Male vs Female Cannabis Plants

Cannabis sativa L. In commercial production, marijuana plants are all genetically female; male plants are destroyed as seed formation reduces flower quality. Spontaneously occurring hermaphroditic inflorescences, in which pistillate flowers are accompanied by formation of anthers, leads to undesired seed formation; the mechanism for this is poorly understood. We studied hermaphroditism in several marijuana strains with three objectives: i to compare the morphological features of this unique phenotype with normal male flowers; ii to assess pollen and seed viability from hermaphroditic flowers; and iii to assess the effect of hermaphroditism on progeny male:female sex ratios and on genetic variation using molecular methods. The morphological features of anthers, pollen production and germination in hermaphroditic flowers and in staminate inflorescences on male plants were compared using light and scanning electron microscopy.
Male vs. female cannabis: How to determine the sex of your plant
Plants have several different ways to reproduce. The most common method is sexual reproduction. Plants that reproduce sexually with seeds are called angiosperms. Hermaphrodite plants consist of single flowers that contain both male and female reproductive organs. Tomatoes are a good example of a plant that is commonly hermaphrodite.
In the world of plants, reproduction can happen in a variety of ways. Monoecious plants produce two different types of flowers on the same plant, and hermaphrodite plants grow single flowers that have both male and female reproductive organs. Cannabis is a dioecious plant, meaning male or female reproductive organs appear on different plants. With cannabis, females are usually isolated away from males—introducing males into a garden will result in pollination, causing females to create seeds.
