There are two types of hermaphrodite plants:
Cannabis really stands out in its flowers—or buds—where unique and intricate formations occur: fiery orange hairs, sugary crystals, and chunky buds enveloped by tiny leaves.
Pre-flowers begin to develop four weeks into growth, but they may take a little longer depending on how quickly the sprouting phase occurs. By the sixth week, you should be able to find the pre-flowers and confidently determine the sex of your plant.
Male marijuana plants
The main stem, or stalk, of a cannabis plant grows straight up from the root system and supports all lateral branches. The stem gives a plant structure and stability.

Females are the prizes of cannabis plants—they are the ones that grow the buds that we all know and love. Anytime you see a picture of a cannabis plant with buds, you are looking at a female plant.
The stigmas of the pistil begin with a white coloration and progressively darken to yellow, orange, red, or brown over the course of the plant’s maturation. They play an important role in reproduction, but stigmas bring very little to the flower’s potency and taste.
Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.
If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
Within a week or so you should see a seedling begin to grow from the soil.
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.
In a nut shell, one can increase the likelihood of one sex or another during the first 2 weeks of life as a growing seedling. To promote your seedlings to be female; increase Nitrogen (for males increase potassium), higher humidity and moisture in the air and soil for females (males lower humidity and dryer soil), fewer daylight hours 14 versus 16/18 hours (for males the reverse) and using blue light in the vegetative state. Red light during the seedling stage promotes males. Red spectrum light is always used to shift the female plants into reproductive growth at the same time changing the day/night hours 12/12.
Cannabis plants are dioecious, male plants and female plants and hermaphrodite misfits with both sexes on one plant. One of the hurdles one must face with this plant is not knowing whether a seedling is male or female and one puts a lot of time raising these seedlings only to find they are all or a large part males. Unless one is growing for seed all one wishes for are females. The boys get killed.
This concerns dioecious plants. Where a plant is either male OR female NOT both as in monecious a plant with both male and female parts for each plant. I’ve read that just by tweaking the environment one can make a dioecious plant within the first few weeks to be one sex or the other!?

In addition, those that have purchased expensive seed ($10 to $20 per seed or more) can relax knowing the sex of their plants can be manually enhanced. Otherwise, cloning was the only option to be sure of females. Hermaphrodites can still pop up anytime with females.
The moral of the story is the sex of a dioecious plant is not carved in stone within the seed. The environment is in a very large way responsible for determining the sex.
Then there are the hermaphrodites, an unknown. It is almost common to one day find just ONE male flower on one of their female plants in the midst of female plants, the fan is blowing all of the time. Blowing that fine fine pollen only later to find that one flower has fathered seed in all of the plants! The process of making seed is a huge energy expenditure and reduces the amount of ‘bud’ or female flower or ‘cash crop’.
Those who try to grow this plant on a budget and don’t purchase both sets of bulbs (blue spectrum and red spectrum) will most likely have chosen red spectrum. As the studies show, red spectrum light used on seedlings will promote males. Bummer. Go get those blue bulbs to have both spectrums!
