Imagine you’d be the one creating the next Tangerine G13!

Make sure there are no vents on and windows are closed though. As the male cannabis pollen is designed to travel with wind – and in this case we’re trying to contain it to not fertilize the wrong (or too many) female plants. Also avoid working with your female plants right after this job, as pollen easily sticks to your clothing and hair.

How To Collect Cannabis Pollen

Hollow stems on male cannabis plants may indicate high THC-production in its offspring

Obviously, only select male cannabis plants with a nice structure and a healthy root system. If possible, cut off a few branches in search of hollow stems. As a hollow stem in weed plants is often an indicator for high THC-production in the plants.

Crossing your female plant with late-blooming males will therefore retain the desired characteristics from your fem – instead of your cross turning into a copy of your male parent. If you’re serious about selecting the right male, make sure you have a separate room for them. As there you can leave them to flower longer, to discover more about their grow characteristics.

Crossing Weed Strains

Because although you can grow male cannabis plants in the same room as female cannabis plants. It’s important to separate the males before their flowers open, releasing their pollen into the room, to avoid uncontrolled fertilization.

Be sure to keep an eye on them once they start flowering, as you’ve now produced ‘regular cannabis seeds’. This means your plants can turn both male or female when they enter the flowering stage. Providing you with what you need to further stabilize your creation into the perfect weed strain.

But genetics isn’t the only thing that affects how your plants grow. Both the plant’s genes and the environment influence the phenotype that you see.

Keep Records! To breed successfully, one of the most important things is to keep great records. Write down which plants were bred together and how their offspring turned out. This lets you keep track of traits that show up in the parents and offspring. This will also help you create new strains because you’ll be able to know what traits to expect when breeding certain plants.

Original crosses created relatively small plants with low potency, but growers have continued to refine and stabilize auto-flowering strains. Over the last decade or so, many breeders from around the world have been working together to isolate the auto-flowering trait in plants that produce high-potency buds and big yields. By continuously breeding the Ruderalis plants back to potent cannabis strains, we now have strains that have kept that auto-flowering characteristic, but are just as potent as modern strains (we managed to “breed out” the phenotypes that didn’t produce good buds or growth patterns).

Evolution of the Cannabis Plant Through Selective Breeding

Incomplete Dominance – Let’s look at an example where the genes have incomplete dominance over each other. In these cases neither version of a gene is “dominant.” Instead they partially affect each other.
