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.”
If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.
What are feminized cannabis seeds?
There are a few indicators that will give you a sense of whether the seed is worth germinating.
These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.
If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.

Marijuana seeds can be feminized by two different methods : chemical ethylene inhibition, and rodelization. In the first method, a chemical agent (colloidal silver, gibberellic acid, etc.) is applied to the plant to inhibit its production of ethylene, a plant hormone that induces female flower production. Rodelization is a less-used technique that involves exploiting a natural self-defense mechanism of the plant. An unpollinated female cannabis plant with fully mature flowers may, in some cases, grow pollen sacs to fertilize itself to ensure its propagation. In both cases, pollen is collected and used to fertilize other female plants. Given the absence of Y chromosomes, seeds that result from the mature buds are female.
Around the middle of the 20 th Century, growers discovered that culling male plants as soon as they display their sexed traits, would result in a crop containing exclusively unfertilized females, yielding cannabis flowers higher in THC that don’t require the removal of seeds before smoking. This seedless cannabis was from then on dubbed sinsemilla, which translates to “without seed” in Spanish. It is also commonly spelled sensimilla.
