Pure OG medical marijuana strain is a classic OG with a fresh fuel odor, a smooth smoke and that great classic OG flavor. Pure OG is a San Fernando Valley (SFV) OG Kush F4 IBL (inbred line).
An IBL is a genetically homogeneous strain that grows uniformly from seed. When you cross two different IBL strains for the first time, it is called the F1 generation. When you cross two of the same F1 hybrid (inbreed), it is called the F2 generation.
The process of selective inbreeding must continue at least until the F4 to stabilize the recurrently selected traits. When you cross two specimens of an IBL variety, you get more of the same, because an IBL is homozygous, or true breeding for particular traits.
Pure OG cannabis generally creates a body high that is relaxing and medicinal. Pure OG has higher CBD than THC which equals to a much heavier, sleepy type of high. Pure OG cannabis strain is good for a variety of medical problems.
