In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.
Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”
Cannabis seeds vs. clones
Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.
Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
Good quality marijuana seeds have a waxy coating around the shell. This is easy to see if the seed is held up to the light because the shell will have a slight sheen.
Seeds can remain viable for three to ten years if stored properly, but more and more seeds will fail to germinate as time passes. Older seeds will take more time to germinate, so growers should use the float test before assuming the viability of their stored seeds. They can speed germination by soaking the viable seeds in water mixed with a few drops of hydrogen peroxide for 24 hours. It is important to watch them closely for signs of opening, as they will need to be removed immediately to avoid drowning.
A lot of information can be gleaned from the texture and hardness of a marijuana seed. After visually inspecting the seeds, growers can pick them up and feel their shell for the following:
When growing marijuana, it is important to identify male plants as early as possible. Just one male plant can pollinate an entire field, so it is critical that male plants are removed before they develop pollen sacs. There are certain signs that a young marijuana plant is male, including the following:
The float test is a more scientific approach to determining the quality of a seed. The test involves filling a drinking glass with spring or distilled water and placing the seeds inside of it. Allow the seeds to soak for one to two hours before determining quality.
If all you get is a bag seed, the only way to know if it’s going to be male or female is to develop it.
Most of the cannabis seeds offered for sale in seed shops are of high quality. In most cases, they exhibit high germination rates of at least 95% and sometimes even higher . On the other hand, seeds from an unknown source may well be defective and eventually lead to the growth of a weak and disease-prone plant with slow growth rate and low harvest potential.
You can tell a lot about the health of a seed by looking at it. Here are a few different things you should look for when deciding whether a cannabis seed is good or not.
How to sprout a cannabis seed
Note: Do this only if you are ready to germinate your plants. Otherwise, it could hurt your seed.
It’s a great test that works for many different seeds – and not just cannabis. Take your seeds and drop them in a cup full of hot water (not too hot) then wait a few hours. If they sink, they are probably good for a crop. If they don’t leak, they’re probably dead and won’t grow.
If you plan to store your seeds for a long time, be sure to keep them in an airtight container in a dark area. Ideally, seeds should be stored in an air-conditioned area (such as inside your home rather than in a shed or garage). A survey shows that cannabis seeds sealed in the laboratory were still viable after 19 years.
If you really want to know if a cannabis seed is capable of germinating, put it in the ground .
