The Serious Seeds’ biggest yielder Chronic was crossed with Remedy, a strain with extremely high CBD content, in collaboration with the CBD Crew. The combination was lab-tested in Spain and all 10 samples had a 1 : 1 ratio of THC and CBD. CBD-Chronic can produce top-yields and is easy to grow and clone. It grows a huge top cola with little side-branching. This first purely medical CBD strain of Serious Seeds is a milestone which enables patients/caregivers to produce big amounts of medical cannabis containing high levels of non-psychoactive CBD. The production of medical extracts (such as Rick Simpson Oil) and lotions, cremes or ointments is made much easier with this strain. CBD-Chronic is a medical strain, which is very well suited to treat the symptoms of diseases such as multiple sclerosis, epilepsy, Tourette syndrome, glaucoma and arthritis.
