Killed my chronic pain right off the bat and gave me a fantastic night's sleep. Also known as Seraden in the medical world of cannabis, this weed can have THC levels as high as 30%. Not for the beginner, however, as these heavily crystal-coated buds pack a mean punch that starts in your head as a big rush and quickly moves across your body. Love love love this strain. Excellent for patients of chronic pain, insomnia, ADD, PTSD, stress, depression and anxiety.
