Why you should buy Sour Tsunami CBD seeds
Sour Tsunami CBD isn’t here to blow your mind. It’s here to balance it. Built from a lineage of diesel-fueled legends and boosted with a rich CBD profile, this strain was born for those who want the benefits without the buzz. It’s a true connoisseur’s CBD cultivar: subtle, complex, energetic, and grounded. You still get the iconic sour-diesel tang, but the experience is smooth, clear-headed, and calming. Whether you're microdosing throughout the day or just looking for a strain that won’t derail your productivity, Sour Tsunami CBD fits the bill beautifully.
With 13% CBD and just 1% THC, it delivers therapeutic effects without knocking you out or over. And the structure? Gorgeous. Expect tightly packed buds, a punchy terpene profile, and hardy growth with high resistance to fungi. Not the easiest to grow, but absolutely worth the effort for anyone with a little experience under their belt.
Strain Overview
Origin
Sour Tsunami CBD is the result of careful breeding between Sour Diesel, NYC Diesel, and a high-CBD cultivar. Each parent brings something special to the table. The unmistakable fuel-soaked aroma comes from Sour Diesel, the smooth uplifting edge from NYC Diesel, and the high cannabidiol content from its CBD parent. Originally bred by Lawrence Ringo, this phenotype helped set the gold standard for functional, flavour-forward CBD strains that still hold up today.
Effects & flavours
Don’t let the word "tsunami" fool you. This one washes in gently and leaves you floating. It’s bright, slightly energizing, and very easygoing. The cerebral lift keeps you alert and focused, while the CBD levels work quietly in the background, smoothing the edges and melting away tension.
Taste-wise, it stays true to its diesel roots. There’s a tart, gassy kick right up front, layered with floral notes and a delicate sweetness on the finish. The nose is bold and funky, but the smoke is exceptionally smooth.
THC & CBD Levels
This is where Sour Tsunami CBD sets itself apart. With THC levels sitting at just 1% and CBD hitting a solid 13%, it’s a strain designed for clarity, calm, and function. There’s no intoxication here. Just a gentle shift in mood, ideal for daytime use, focus-driven tasks, or taking the edge off without losing your edge.
Terpenes
The terpene profile is surprisingly elegant for such a punchy strain. Linalool brings a floral softness. Alpha Bisabolol adds a hint of chamomile warmth. Terpineol throws in subtle lilac and herbal notes. Together, they don’t just shape the aroma. They enhance the therapeutic qualities, making this a go-to for anyone seeking calm clarity with real flavour.
Growing Sour Tsunami CBD Seeds
Grow Difficulty
This one leans toward the advanced side. Sour Tsunami CBD is a bit more sensitive than your average indica-sativa hybrid and requires a grower who’s dialed in their environment. But if you’ve got the basics locked down and don’t mind giving her a little extra attention, she’ll reward you with dense, aromatic buds and very respectable yields.
Indoor vs. Outdoor Growing
Sour Tsunami CBD adapts well to indoor setups, greenhouses, and controlled outdoor environments, especially in temperate or arid regions. Indoors, you’ll want to keep an eye on humidity and airflow to maximize that natural resistance to fungi. Outdoors, she prefers climates that don’t swing too wildly. Thanks to her strong genetics, she’s got the chops to push through some adversity.
Flowering Time & Yield
Expect flowering to run between 49 and 63 days, depending on conditions and phenotype. Indoors, yields range from 1.1 oz per square feet to 1.5 oz per square feet. Outdoors, you can see between 14.1 oz per plant and 21.2 oz per plant, especially if you give her space to stretch and plenty of light. Heights typically reach 35 inch to 51 inch inside and anywhere from 43 inch to 67 inch under the sun.

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.

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!

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

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.

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!
