Grafting as a process can be traced back 4,000 years to ancient China and Mesopotamia. Although it isn’t so popular among cannabis growers, cannabis plants are perfectly suited for grafting.
The Whip Grafting method is arguably the most popular method for grafting cannabis plants as it’s simpler and takes less time. Here’s how it works:
HOW TO GRAFT CANNABIS
One of the big benefits of grafting cannabis is that it allows you to grow multiple strains from a single tree. This comes in handy when you’re looking to experiment with new strains that you’re not completely familiar with. Rather than committing to growing an entire plant of a new strain, you can simply take a clone or seedling and graft it onto a rootstock. From there, you can let the strain grow out until harvest time and test it before you decide whether to add it to your garden for good. Again, this is really beneficial for growers working with limited amounts of space.
Here’s how to graft cannabis at home. Make sure to read these instructions through a few times before getting started. Grafting is a delicate process and you’ll want to make sure you know exactly what you’re doing before you get started.
Grafting is usually left to experienced gardeners. However, there is no reason new growers can’t try grafting at home and see great results. In fact, if you’ve ever tried to clone cannabis (or any other plant for that matter), you should have no problem with grafting, as the processes are quite similar.
By the way, don’t ignore growing environment when breeding. A clone of a plant is a genetic copy of the original and will grow the same when exposed to the same environmental conditions . However, despite being a clone, the plant will NOT grow the same if you expose it to different conditions to what the original plant grew in.
Place the bag of pollen over a stem which has several buds growing. Shake the bag to ensure the buds get coated with pollen. Cover the site with the bag for a couple of hours and shake it again to get the last bits of pollen out. Leave the bag on the site for a few more hours and remove it carefully.
As a consequence, crossbreeding marijuana plants is a lengthy, unpredictable, and utterly frustrating experience. Many breeders begin with a clone-only strain and try to develop a seed-based strain that has the traits of one of its parent plants. If you go down this route, expect a different result with every seed. It is normal for breeders to sprout well over 100 seeds from a single variety to find the ‘true’ representation of what they sought.
Crossbreeding – Desirable Traits
Growers visiting regions such as the Hindu Kush Mountains would have been greeted with strains of cannabis with traits they had never seen before. They brought back dozens of seeds and evaded law enforcement in the process! Next, they mixed the seeds with other breeding stock to grow ‘new’ strains that had many of the traits found in the landrace strain.
Back-crossing involves taking a plant and crossing it with one of its parents or a close family member. This inbreeding helps create offspring with genetic similarities to the chosen parent. Every offspring plant created through back-crossing will probably carry two versions of the chosen parent’s genes.
