Hybrid seeds are bred from different cannabis strains to produce certain features and effects. This is man-made attempt to customize plants with certain characteristics typically found in sativa, indica, and ruderalis strains. Successful hybrid seed inherits the best qualities from their parents. Often, hybrids provide a more balanced combination of sativa and indica effects.

Also, they can have the quality yields of indica along with the fast vegetative growth of the sativa. The reason they make up most of the strains on the market is that they can blend attributes of each strain. Popular hybrid seeds include Bruce Banner #3, Gorilla Glue #4, Blue Dream, Granddaddy Purple, and many more.
