Cataract Kush is a hybrid medical marijuana strain which was created by crossing two of the most popular indica strains – OG Kush X LA Confidential. Hence, this is a full-on indica strain. Originally, this medical marijuana was developed by 'DNA Genetics'. This strain is featuring plenty of snowy crystals. When properly cured, the nugs of this plant would appear to be grayish-black in color. CBD content is also found to be high in this strain and hence, it can deliver a strong corporal effect that would keep on building long after use.
