When a breeder crosses two genetically distinct strains of cannabis, a Hybrid is created. Hybrids can happen naturally in nature or occur more pragmatically in order to combine the desired traits of two strains into one. Hybrids usually blend sativa and indica qualities with different rations depending on the strain.
Use of Term
Whenever I want an Indica and Sativa at the same time, I start looking at Hybrid strains.
