As the name suggests, hybrid cannabis strains are the result of a crossbreeding either pure strains or other hybrids into a new strain. One of the earliest hybrids is known as “Skunk”. This is the first known crossing of an indica and sativa, but it was certainly not the last.
Strains are bred primarily for:
Specific cannabinoid content
Many hybrids are a mix of both indica and sativa “parents”. This allows breeders to determine the kind of impact the strain will have. Going for a couch-lock? Try an indica-dominant strain. Seeking cerebral creativity? Look for sativa-dominant strains. Want an autoflowering strain? That will be a hybrid of a ruderalis, plus another strain. As medical research expands, more and more breeds are being created to sustain specific concentrations of certain cannabinoids. Many strains of cannabis will maximise THC or CBD. Medical cannabis for children, for example, is bred from specific hybrid strains of cannabis that will always contain low levels of THC, but high amounts of CBD.
Growing in or outdoors imposes its own restrictions on cultivator choice. Sativas grow tall and tree-like. Indicas tend to be shrubby. However, hybrids can be selected for size, bushiness, and other features. Some sativa hybrids, in other words, can be mistaken for indicas.
These strains are all crossed at some point with a ruderalis parent. What this means is that your plant will bloom regardless of hours of light exposure.
