Sour Haze strain guide

2 min read · Updated October 14, 2026 · WeedDB editors

Sour Haze is a sativa that pairs Sour Diesel with a Haze plant, at least according to most listings. People know it for a sharp, sour smell of diesel and citrus and an upbeat, focused feel. It also goes by Sour Diesel Haze.

Where does Sour Haze come from?

The cross most often given is Sour Diesel with a Haze. Which Haze is never named, and one strain database notes that this parentage is widely agreed but not confirmed. The original breeder is not well documented either.

Both parents are famous for energetic, head-first effects, so the pairing explains a lot about how people describe it. You may also see it labelled Sour Diesel Haze or Sour Haze OG.

What does Sour Haze smell and taste like?

The smell is sour and pungent first, with diesel, skunk and earth. The flavour turns brighter, with citrus, lemon and grapefruit and a touch of sweetness. A few reviewers mention floral notes too.

Terpinolene is listed as its main terpene, followed by myrcene and limonene. One reviewer said the terpinolene makes it a little less skunky than straight Sour Diesel.

Sour Haze effects: what people report

People most often describe Sour Haze as energetic, focused and talkative, with a happy, sometimes giggly head feel. It's generally treated as a daytime strain.

These are reports, not promises. Feeling anxious or paranoid comes up, especially with larger amounts, along with dry mouth and some dizziness. How it feels depends on the product, how much you have and your tolerance.

How strong is Sour Haze?

Listings put Sour Haze at about 19% to 26% THC, with very little CBD. That's strong, and racy sativa strains can feel like a lot if you go too fast.

Start small and wait before having more. If you're curious how sativa and indica labels compare, see our indica vs sativa guide.

Buying Sour Haze in Canada

Since the Haze side isn't named, different growers may be working with different plants. Check the producer, the THC and CBD numbers and the packaging date on the label.

Sour Haze vs Sour Diesel

Sour Diesel is the better-known parent and the source of the fuel in Sour Haze. Sour Diesel is known for a heavy, pungent gas smell and a fast, energetic high. Sour Haze keeps the sourness and energy but brings in more citrus and a fresher, Haze-style lift, and reviewers find it a little less skunky. If you want the full diesel punch, go with Sour Diesel. If you'd like it a bit brighter and fruitier, try Sour Haze.
