While growers may not be able to determine the sex of a seed, does the environment have anything to do with it? This is something else that has been hotly contested online.
Growers know that hermaphrodite plants can be just as harmful to crops as male plants. Therefore, it’s very important that every grower understand how to sex marijuana plants. Particularly if they’re not using feminized marijuana seeds that will give them only females.

Common myths on identifying the sex of a cannabis seed
MSNL Team / 3rd February 2017
The chart states that one can determine the sex of a cannabis seed by just looking at them. Within the chart, five cannabis seeds are shown. Three of these are female and two are male, supposedly. This chart says to look for a crater at the bottom of the seed. It explains that females will have a depression that is perfectly round. While males will have a crater that is misshapen and not uniform. However, this is simply not true. The craters found in cannabis seeds have nothing to do with the sex of a seed.
This will mostly happen when a plant is stressed by its environment. When this happens, the plant may think it’s going to die and as a result, will change itself into a hermaphrodite plant. By doing so, it will be able to self-pollinate itself and survive.
We know that determining the sex of cannabis seeds cannot be done. However, it’s unclear as to whether environmental factors have any place in determining the sex of marijuana plants.
Most people grow cannabis for the potent buds. That means growing female cannabis plants. Male cannabis plants do produce THC, but not generally in the amounts worth the inconvenience of growing them. Few people (other than cannabis breeders) want to see seeds in their cannabis buds.
Female plants produce the buds we are familiar with. Male plants produce small pollen sacs, these look like small balls. When they open they look like miniature bananas, releasing cream-coloured pollen dust.
What does a hermaphrodite cannabis plant look like?
If you grow from feminised cannabis seeds or autoflowering seeds you may rarely see male plants. Male pollen sacs are easy to see, allowing males to be easily identified. Sexing cannabis pictures are a useful reference if you are new to the subject.
Hermaphrodite cannabis plant pictures can show varying numbers of pollen sacs. Small numbers of them can be plucked off and the plant can be saved. Heavily affected hermies are often simply removed. Any seeds produced by cannabis hermaphrodite plants should be treated with caution – they may give rise to hermaphrodite cannabis plants if germinated.
Male vs female cannabis plants look different and grow a little differently too. Male plants are often taller, giving them a pollen distribution advantage when their pollen sacs eventually open. The pollen sacs form at the nodes on the stem. Pollen can be collected and frozen if required e.g. for breeding purposes.
