how to get your own weed strain

A single male plant can pollinate tens of females. “It’s always a good idea to have only one male, genetically speaking, per pollination effort,” says Pennington. “A healthy male can pollinate up to 20 females, and by pollinate, I mean absolutely cover the plant with seeds.”

The mature male will grow pollen sacs within the first couple weeks of its flowering phase. Pollen will release from the sacs, move through the air, and land on the female plants, pollinating them. Having an enclosed breeding chamber is important to contain the pollen and also to prevent outside pollen from getting in.

How to Breed Cannabis Plants

Cannabis plants can be either male or female. Cannabis consumers are mainly concerned with female plants, because only females produce the sticky buds that we all know and love. But male cannabis plants are important for the breeding process, as they are needed to pollinate the bud-producing females.

After two parent strains are selected for breeding, a male and several females are put into a breeding chamber to contain the pollen. A breeding chamber can be as simple as an enclosed environment with plastic sheeting on the sides, or a specially designed sterile environment for large-scale breeding.

High-quality breeding still doesn’t stop there. Once a breeder has crossed a strain and narrowed down a phenotype and finally has the one, they will usually backcross that strain to strengthen its genetics.

Most importantly, breed plants you like! 🙂

Unfortunately most breeders can’t grow dozens or hundreds of plants at a time, so it’s helpful if you have other growers willing to grow your seeds out and let you know how the plants turn out.

But in addition to the percentage of THC or CBD, there’s a lot more to the overall effects of cannabis. There are many cannabinoids and terpenoids that we haven’t studied, and these all can change what effects the buds will produce. Some growers are starting to breed for other traits besides color or THC/CBD levels, paying more attention to the nuances of different strains and their effects.

And to make things more confusing, every cannabis bud produces a bouquet of many different smells. Because of this complexity, it can be difficult to “lock in” a certain smell in a strain, especially smells that are recessive traits. Without any way to actually “measure” the smell, you have to rely more on your personal feelings and gut instinct.

There are many phenotypes that show up in mixed heirloom strains like this, and unique genetics you may not be able to find in most modern strains.

A famous example a local plant that rocked growing world is the “Ruderalis” plant. People might not consider it a landrace since it doesn’t seem to be actively cultivated by local growers, but it is a local plant that’s been mixed into many breeding programs around the world.

In fact, the environment plays a really big role in how your plants turn out.
