Hummingbird Genetics

Hummingbird Brand Cannabis Seeds 

Our marijuana seeds for sale are known commonly as F1 seeds—the first generation of a cross between two different strains of cannabis. Our seeds are bred from parent strains that show strong tendencies toward certain desirable traits, such as high THC or favorable aromatics. The beauty of each cannabis seed pack you buy from Hummingbird is that you’ll get a variety of F1 seeds, each holding its own unique potential for developing different amounts of traits from the parents. Variation among the seed pack is a wonderful thing. With each seed pack, the home grower will find traits they like and connect with. 

Plant Breeding 

Agriculture has been practiced for over ten thousand years. Plant breeding, a foundation of agriculture, is the intentional manipulation of a plant species to create desired genotypes and phenotypes. Classical plant breeding uses deliberate interbreeding (crossing) of closely or distantly related individuals to produce new crop varieties or lines with desirable traits. Plants are crossbred to introduce traits and genes from one variety or line into a new genetic composition. 

Progeny—descendants—from the cross are then crossed with the high-yielding parent to ensure that the progeny are most like the high-yielding parent (backcrossing). The progeny from that cross is then tested for the amounts of the desired traits; plants showing high levels of the parent traits are further developed. Plants may also be crossed with themselves to produce inbred varieties for breeding. 

Cannabis Plant Breeding 

Cannabis breeding can be compared to breeding garden roses. Garden roses are predominantly hybrid roses that are grown as ornamental plants. When you mate two different species of roses together, you don’t end up right away with a distinctly new type of rose. Instead, you end up with roses that exhibit traits of both the parents. 

Through inbreeding and other breeding techniques, you can stabilize the genetics and end up with something new you could call a “cultivar,” or a true-breeding phenotype. Numerous rose cultivars have been produced over time. 

In the case of cannabis genetics—now legally available in Colorado—there are very few true breeding cultivars. It takes many generations and years of inbreeding to create parents with homozygous gene expression and that breed true for those traits with every seed. Today, variation in seed characteristics is inevitably high. 

When you grow a pack of F1 seeds, all plants will have similar as well as varying characteristics. Some plants may exhibit more traits of the mother and some more of the father, while others will show an even combination of both. 

 

How to Grow Marijuana 

 

Tips for Germinating Marijuana Seeds 

  • Line the bottom of a ceramic plate with a few layers of paper towels. Wet the towels and drain off the excess water from the plate. 

  • Place the seeds on top of the towels. Then, place another layer of towels on top of the seeds and first layer of towels. Wet this layer as well and drain off the excess water again. 

  • Place another ceramic plate on top of the first to create a “clamshell” with the two plates. 

  • This will create the perfect environment for the seeds to begin germinating. Make sure the towels stay moist but are not in standing water. 

  • Place the plates in a warm area, away from direct light. 

  • Check the seeds every day. 

  • Sometime between 24-72 hours after making the clamshell, the seeds will begin to show their white root. Once the root sprouts from the seed, place it root facing down, into your preferred growing medium. 

  • Cover the seed with about a 1/4 inch of soil, but do not plant the seed too deep, as this will not allow access to light and will kill the seed. 

  • Make sure to keep the medium moist and do not let it dry out (this will kill the seeds quickly). 

  • Place a fluorescent type growing light with a “plant-growing” bulb at 6″ above the seed. 

    

Tips for Growing Marijuana 

Proper growing conditions: 

  • 68-75 ˚F degrees is ideal 

  • 30-45% humidity is ideal 

  • Keep the lights on for 18 hours until the seedlings have grown to a size you prefer. (This amount of light replicates the hours of natural sunlight in the early growing season when cannabis grows in the wild.) 

  • Once the plant is a size you like, switch the light cycle to 12 hours on and 12 hours off. This cycle will induce the flowering cycle of the plants. It is extremely important that the 12-hour dark cycle is kept completely dark, otherwise, you will end up with seeded plants (due to the interruption of the light cycle). 

  • The plants will stretch upwards usually between 12-18″ depending on variety, so be aware and decide your ideal plant size based upon this information. 

  • For the flowering cycle, a high-pressure sodium light will work best and should be kept 3′ away from the top of the plants. 

  • It is imperative that unnecessary stress is avoided when growing seeds. Stress such as too dry, too wet, underfed, light cycle interruptions will cause the seedlings to become males, which will be unwanted in your garden. 

  • Cannabis is a dry/wet cycle plant. This means that it prefers to dry out a bit, then be watered again, and so on. This does not mean that you want the plant to dry out completely, but do let it dry somewhat and then water it. The quickest way to kill a plant is to overwater or underwater. Just try the wet/dry cycle of watering and use your judgment. It will be a learning process and will take some time to master. 

  

Sexing Marijuana Plants 

The importance of sexing marijuana plants, or identifying the sex, comes with the consumer demand for buds without seeds—also known as “sinsemilla.” 

Sinsemilla is robust cannabis produced by female marijuana plants, intentionally kept seedless to obtain a high resin content. This is done by preventing pollination by simply getting rid of the male plants. 

Male cannabis plants do not produce desirable amounts of THC and are full of seeds. These qualities are not wanted by most cannabis consumers. In your pack of F1 seeds, you will find males and females. Beginners might find that using a magnifying glass is helpful while identifying the sex of the plants. 

Both male and female cannabis plants begin to produce flowers 10-14 days after the plants are in the flower cycle (12 hours of light, 12 hours of darkness). The male flower sites will begin to produce pollen only a few days after the flowers begin to develop. 

The image on the left shows the development of the male flower at one week of the flower cycle, while the image on the right shows the development of a female flower. 

Once you have identified the sex of all of your cannabis plants, simply kill the male plants and compost the green waste. This is time-sensitive due to how quickly pollen is produced after the flowers begin to develop.
