Sour Tsunami

Sour Tsunami is a high-CBD strain. In fact, it's one of the first CBD strains to become popular. With nearly a 1:1 ratio of THC:CBD, this strain is popular among those with seizure disorders and anxiety.

Sour Tsunami is a high-CBD hybrid. It was first bred in Humboldt by Lawrence Ringo of Southern Humboldt Seed Collective. He actually bred this strain to address his own medical condition, and it quickly became one of the first high-CBD strains to gain popularity.  Ringo had severe back pain and did not want to take opioid pain medication. So, he developed this strain to use instead.

This strain is primarily a cross between Sour Diesel and NYC Sour Diesel, yet there are a couple of other strains in the mix as well. These include Double Diesel and Ferrari. It took 4 years to develop this strain, and the results are quite fantastic. The CBD content in Sour Tsunami typically runs between 10 and 13%. The THC content usually gets as high as 10% So, this strain produces close to a 1:1 ratio of THC:CBD.

Sour Tsunami is a potent medical strain. The psychoactivity is either very mild or non-existent. Those with seizure disorders, multiple sclerosis, muscle spasms, and pain may find relief with this strain. It's also popular among those with inflammatory conditions like arthritis. The high CBD content makes it an excellent choice for those with anxiety disorders.

Recreational users may not get much out of this strain, but those looking for a mild and calm herb to ease stress may enjoy Sour Tsunami. It's also a good option for folks who are interested in cannabis but don't like the experience from high THC strains.

Growing Tips

Coaxing the CBD out of this strain can be difficult. Sour Tsunami produces several phenotypes, and your chances of getting a high-CBD strain are only 25%. It's recommended to send a sample of your plants to a testing lab when they are about 3 to 4 weeks old to see what the plant is producing. If they are producing CBD, take cuttings from those plants to grow from clone. The growth on this plant is tall and lanky. It has long internode spacing and produces heavy, round buds.
