About Sour Tsunami

Sour Tsunami is a well-balanced, CBD-rich strain that is 60 percent Sativa and 40 percent Indica. Many CBD strains are Indica-dominant, but this one edges towards Sativa. This strain is a cross between Sour Diesel, NYC Diesel, and a local California variety, Ferrari. 

The THC is low at 10 percent and the CBD is very high at 11 to 13 percent and some concentrates may have CBD as high as 30 percent. Sour Tsunami is one of the first to become famous for high CBD.

Recreational users that are accustomed to average or high THC levels might pass this one by. Those that are used to the weed from days gone by and feel that the current strains are too strong, might want to try it. Others may want to experience the synergistic effect that equal parts THC and CBD produce as different cannabinoids interact with the body in individual ways.

Medical users should definitely check it out due to the very high CBD level. It will alleviate pain, without making you really high and incapacitated on the couch. Lawrence Ringo of Southern Humboldt Seed Collective created this strain to treat his own back pain, which he says disappears in 15 minutes after indulging in Sour Tsunami. 

Conventional medical studies have found that CBD alleviates seizure disorders and works on alcoholism and cancer. People with less severe medical conditions such as insomnia, stress, and nausea could also try Sour Tsunami. Some also find CBD to be helpful when treating acne and other skin ailments. Whatever the reason, you will gain symptom relief while keeping a clear head.

Grow this strain and you will have flowers in 9 weeks that smell sweet and musky. Like many CBD-rich strains, producing bud with high-CBD is not a given. In fact, you’ll only have a 25 percent chance of getting to that level. To increase your chances, work on variety in your strains and source. Buy seeds and cuttings of a few different CBD-rich strains. 

To increase your chances, use a testing service like Pure Analytics to test the seedlings at 3 to 4 weeks, before the flowering stage. Take a couple of nodes from the top of the plant, dry them out, and send for testing. Once you identify which plants are high in CBD, you can take cuttings to develop right away.

Sour Tsunami is the best strain for pain that I’ve come across so far. Thank you to the magic makers that help me every day with chronic osteoarthritis pain. I use it for dabs in shatter form and I hope orhers can get it in whatever form they need. And it gives me a nice little head buzz even tho it’s lower in THC. Cheers!

I’m a newbie to all of this and get pretty nervous when trying it but this was a great one for me to start with. Took a few hits but didn’t even smoke half of my pre-roll and I felt great. I didn’t feel “high” but I did feel a slight buzz. Definitely had a head and body effect. It had a relaxed, calming affect on me and I felt happy overall. I was still able to function like normal but could easily use it to help me fall asleep. Definitely going to be using this one often for my anxiety! I recommend for people who are nervous with the higher HTC levels to try this one out.
