Let a wave of calmness crash over you, with Sour Tsunami CBD. Just like our Sour Diesel, she is a Sativa dominant hybrid. However, unlike that Diesel strain, Sour Tsunami has very high CBD levels, around 13%.

CBD is known for its relaxing and calming properties and is a non-psychoactive cannabinoid. Thus, it does not have psychotropic effects that affect the nervous system or even the psyche (perception, mood, consciousness).

However, CBD does offer many medical qualities: analgesic, anti-inflammatory, and also anti-epileptic and anxiolytic. It is mainly used for diseases such as fibromyalgia or multiple sclerosis, but can be used for various purposes and is therefore a perfect strain for anyone who wants to experience the benefits of CBD pleasantly. So buy the feminized Sour Tsunami seeds and grow this rare CBD strain yourself!

Why you should buy Sour Tsunami seeds:

  • High in CBD and (very) low in THC

  • Good yields

  • Can be grown in a variety of conditions

  • Delicious sour, flowery, diesel taste


Growing Sour Tsunami CBD (indoor and outdoor)

Sour Tsunami is a fantastic CBD strain to grow. She is an Indica (40%) - Sativa (60%) hybrid strain and therefore slightly Sativa dominant.

You can grow this wonderful variety under different circumstances. You can think of indoor growing (in a grow tent), in a greenhouse or in the open air. The choice is yours!

As a Sativa-dominant hybrid, Sour Tsunami is recommended for people with some gardening experience. In fact, you have to be careful with temperature and humidity. The fact that these seeds are feminized, however, makes the task of growing a good yield a lot easier. 

Flowering time

It doesn't take long before you can collect and dry your harvest. All in all, the flowering phase of Sour Tsunami CBD takes about 49 to 63 days.

After this short flowering period, you can look forward to cutting off all the buds. In doing so, there is a good chance that you will realize a great harvest.

Take great care in the drying and curing process for ultimate quality weed.

Plant height

Sour Tsunami is an exceptionally stocky Sativa dominant strain when it comes to height, which will please those with limited indoor space. She grows to between 90 and 130 cm indoors and reaches a maximum height of 170 cm outdoors.

Sour Tsunami yield

Sour Tsunami cannabis plants are known to develop lots of weed. The maximum yield indoors is 350 - 450 g/m². Outdoors, in warm, sunny conditions, the harvest is usually better with 600 grams per plant not being uncommon.


  • Harvest in early October for optimal results

  • Optimize your harvest by using a training method like SOG or SCROG

Effects of Sour Tsunami CBD 

CBD buds are often used in self-medication to "feel good". For example, they help to recover after exercise or improve the quality of sleep. All these properties make Sour Tsunami an excellent choice for those looking to treat (a range of) medical conditions.

Sour Tsunami CBD is a powerful medicinal strain. Its psychoactivity ranges from mild to none. It may be suitable for people with multiple sclerosis, epilepsy, muscle spasms or chronic pain. She is also known for her relief of arthritis and other inflammatory diseases.

With an absolute maximum of 1% THC, you won't get high from Sour Tsunami. However, people who want to relax will love it.

Side effects

Sour Tsunami is not associated with any adverse side effects other than the infamous dry eyes and mouth. So keep a bottle of water nearby to stay hydrated.

Smell and taste

One of the most notable features of Sour Tsunami is its wonderful smell and taste, which can best be described as citrus, flowery and sour.

Sour Tsunami is also known for its complex terpene profile. A cannabis plant's terpenes provide the distinguished aroma, but experts believe they may also provide medical benefits. The main terpenes in Sour Tsunami are pinene, myrcene, and terpinolene. 


Sour Tsunami belongs to the first generation of CBD strains that have become incredibly popular. This high CBD content strain is the result of a cross between Sour Diesel and NYC Diesel. 

Originally, Sour Tsunami was developed in Humboldt, California, by Laurence Ringo of the Southern Humboldt Seed Collective. Ringo suffered from severe back pain and was unwilling to take opioid medication. So he developed this variant to use on himself. It ultimately took Ringo four years to create the Sour Tsunami strain. However, the results were nothing short of fantastic.

I purchased 10 Sour Tsunami seeds. They arrived promptly in a discrete envelope. All ten sprouted. Thank you! I can't ask for more than that. Also, thanks for carrying this hard to find strain of CBD!

Gord (Verified customer) 2021-03-25

Ordered seeds, 10 pack of Sour Tsunami arrived here in Toronto Canada took just over a week to arrive, will start the germination process in one or two days and document progress. Plan to grow outdoors and indoors.

Brad (Verified customer) 2020-10-31

I must have gotten the wrong seeds or something. I was beyond stoned

VeryHappyCustomer!! (Verified customer) 2020-09-28

100% Germ rate within a few days. I just could not wait to leave a review about the customer service and delivery guarantee. My goods got stuck in the post office for months. My bad! I did not complain sooner, but as soon as I did, they replaced it. I received the new pack in less than 3 weeks. I strongly recommend WEEDSEEDSEXPRESS! I will leave another review about strain.

Kushmaster (Verified customer) 2020-02-10

Wow! I thought I had to wait for at least two months with this corona shit, but I got my seeds in two weeks, sick! Packaging is super stealthy and professional. Great job

Ray Lakeman (Verified customer) 2019-11-27

This variety is excellent, produces well and an easy grow (but maybe a little easy to overfeed). I haven't tried Sour Tsunami CBD before, but the results we've got line up perfectly with what you'd expect from this sort of medical marijuana. The guys are awesome too, very helpful in every way!

slindy66 (Verified customer) 2019-11-26

Oh, and I agree with a previous post...this is NOT a strain for beginners to grow! Takes a lot of TLC and persistence. But worth sticking with it.

slindy66 (Verified customer) 2019-11-26

I am just super excited to find Sour Tsunami CBD for sale! I'm sure we all know this is a hard strain to get ahold of. Hardly any dispensaries here in NM even sell the bud! Once in awhile ONE of the local ones has it. We have been known to buy an ounce at dispensary prices to make our edibles! Anyway, THANKS!!!

USVET (Verified customer) 2019-09-10

Even though the specifications says it's suitable for beginners I would highly recommend to read a lot of growblogs before you buy these seeds. It remains a photo period specie so you need some knowledge about changing the light scheme to get your strains into flowering but if you do you can definitely achieve great yields and a fantastic high quality CBD weed. Personally the weed provides such a great calming effect. I suffer from various chronic pain complaints but by making edibles of the weed my pain has dropped dramatically. I am therefore very grateful offering the Sour Tsunami CBD seeds. Because of you, the quality of my life has increased dramatically

lilianh123 (Verified customer) 2019-07-29

Ordered these seeds on June 20th originally, all seeds received were either broken or damaged, as they were all shipped in a small bag together with some bubble wrap taped around it. I was then told these re-shipped on July 5th, no word of the seeds to date. I have not received anything and the tracking does not help as it has 3 day delay, however it did say they arrived in the country of destination July 13, we are almost into august and I feel I have wasted my time waiting for these seeds. I am very disappointed, the reviews seemed so good, yet so deceiving!

David (Weedseedsexpress) replied on 2019-09-17

Hi Lilian, We are very sorry things didn't worked out well for you. That's really not how it supposed to be. In consultation with you we have sent you a refund. Hopefully we'll speak another time again. Cheers, David

Best service i have ever had in my life. No joke and i live on the other side of the world from this company. All seeds germinated, not 1 issue. Thank you weed seeds!

Deloach12 (Verified customer) 2019-06-14

Satisfied with your service. Pretty fast delivery even in NZ. Packaging was solid and pretty stealth. Will buy more soon. Have a good day

Pamela (Verified customer) 2019-05-01

Kev (Verified customer) 2019-04-29

Had an issue with my payment but Dave helped me in a great way. Even send me a little bonus. Really appreciate that Dave. Seeds seem to germ nicely but i will wait another 48 hours for some longer tails. Will update another time

Jeraldy R. Gage (Verified customer) 2019-03-19

Altough i had my doubts, after growing and smoking the weed i can say it for sure. This is the real deal! Thank you for selling the Sour Tsunami CBD guys. I'm very sure you gonna help a lot of people in need. I'll spread the word!

R. (Verified customer) 2019-03-10

Amazing service, seeds did arrive abet late. But that was due to canada post issues . very responsive and also they offered if the seeda would not arrive after 21 days they would re-ship my order again. I would recommend this guys for sure and would shop from them again.

Jeremy (Verified customer) 2019-02-25

Although these are clones, i never expected to find the seeds to grow CW by myself. The results are truly amazing! Exactly the same taste, effects and flavors so this must be coming from the original CW. Guys you are amazing having this strain in you assortment. Just bought another 10 seeds and hoping it will arrive just as quick as last time.

jasondence (Verified customer) 2019-01-10

Good genetics, charlotte would be proud! :p But no kidding, this is a wonderfull plant, as soon as the plant arose from the soil my heart was struck by cupid. I wanted to sleep with this little baby and nurture Charlotte's web to maturity.Ofcourse, my wife protested. Okay, Joker off! I germinated 9 of the 10 seeds succesfully. The next stages went well, didn't use any chemicals just water and fertile soil. As soon as I put Charlotte's web into flowering state the aura changed and I felt loads of positive vibes. I recommed Charlotte's web to everyone!

Raven M. Cook (Verified customer) 2019-01-01

If you are looking for a high quality CBD strain that is easy to grow and produces good yields, Sour Tsunami CBD is exactly what you need.

Thomas Arner (Verified customer) 2018-11-25

From my experience I can say that strain is very good for medical use. Growing the plant was not difficult either. Even with my limited experience, I have been able to achieve good harvests.

Crowder Jay (Verified customer) 2018-10-12

Since I started growing and smoking Sour Tsunami CBD, my depression has clearly decreased. The effect ensures that my emotions stabilize, even at a low dose.

Fuentes (Verified customer) 2018-09-09

I had been looking for a high quality CBD strain for a while, so I would be better able to function during the day. On advice of weed seeds express, I bought these seeds and I am very happy with my purchase. Breeding went without problems and the plant was pretty quick to harvest. Although I feel that this is more a 1: 1 strain, my headache is gone and I can concentrate better.

Keach (Verified customer) 2018-07-18

Growing Sour Tsunami CBD was very simple and the weed has a high quality. This strain is also very suitable for making CBD oil. The effect of the weed is great. Very relaxing for the body, but also for the mind. I recommend this strain for people who suffer chronic pain or other medical (psychic) ailments.

Post (Verified customer) 2018-07-02

The effect is exactly what I expected. No psychological effect, but a completely relaxed feeling. The CBD clearly has the upper hand. I can therefore recommend these seeds to anyone who wants to grow a CBD strain.

R. Ruble (Verified customer) 2018-04-27

The Sour Tsunami strain is among my favorite strains. Very easy to grow if you have a bit of experience. The plant has an average height so an indoor cultivation is very suitable. Moreover, the yields are good, the weed is of high quality and the effect is amazing chill to the body

Bobby Martins (Verified customer) 2018-01-05

Unfortunately, my harvest failed because of mold that arose at an early stage. I therefore already had to harvest the plants in week 7.

F. Stewart (Verified customer) 2018-01-02

Thank you Weedseedsexpress for the seeds and advising this strain! I experienced a great service and the shipment was really good. Because of the THC high of many types of cannabis I often become paranoia. However, I have no problems with Sour Tsunami CBD. Because of this I am able to smoke a this weed every night without the unpleasant side effects. Personally I use this weed for treating chronic pain in my feet and it works very well. Moreover, I feel calm and experience fewer fears.
