MarijuanaGrowGuide - Growing Marijuana Guide - Sexing Plants

If you bought feminized seeds, you don't need to do this!

Your plants will usually begin to show signs of their sex before flowering, but the signs are quite subtle. You will most likely have the best luck and make the least mistakes by waiting until the plants have been flowering for a little bit. If you don't see signs of sex yet, you can start the Flowering Stage.

This page includes both botanical drawings and photographs of males and females so that you can differentiate between males and females as easily as possible. The differences can most easily be examined by using a magnifying glass. You want to look at the nodes, where the branches meet the main stem.

The preflowers of the male and female are quite distinctive. The male preflower consists of short rounded structures, whereas the female preflower consists of long hairs. Look for these features. The images on this page should help you identify the sex of your plants.

The pictures below are botanical drawling of the differentiation process (left), a male plant (middle), and a female plant (right).

The pictures below are photographs of a male plant (left) and a female plant (right) with the points of interest highlighted.

Once you've determined the sex of your plants, you should remove your males to allow the females to grow sensimilla. This will certainly be a sad time for you as the boys you raised so caringly now must go off to their deaths, but this is the price of good marijuana. Give them an honorable funeral and if you haven't already, it might be time to start the Flowering Stage.
