Blackwater strain guide

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

Blackwater is an indica-leaning hybrid of Mendocino Purps and SFV OG. People know it for a sweet grape smell with pine and lemon underneath, and for a heavy, sleepy feel that most save for late in the day.

Where does Blackwater come from?

Two strain databases agree on the parents: Mendocino Purps, a purple strain from Northern California, and SFV OG, an OG Kush cut from the San Fernando Valley. You will also see it written as Black Water or Blackwater OG.

Retail listings often credit the seed company Cali Connection with the cross, and some say its seed version swaps in Tahoe OG for SFV OG. We couldn't confirm the breeder from an independent source, so treat that credit as not well documented.

What does Blackwater smell and taste like?

Most descriptions start with sweet grape and berry, a nod to the Purps side. Behind that sits earth, pine and wood, with a light lemon note. Some people also pick up gas and a nutty edge, which fits the OG parent.

One strain database lists myrcene as its top terpene, followed by caryophyllene and limonene. Myrcene brings the earthy, musky side, caryophyllene a peppery bite and limonene the hint of citrus. The taste usually follows the smell: sweet fruit up front and pine on the finish.

Blackwater effects: what people report

Reports lean heavily toward sleepy and relaxed. People describe a full-body feel that builds slowly, with a happy, foggy headspace on top, and hunger comes up a lot. Many say it's not one for getting things done, and call it a late-night strain.

These are experiences people report, not promises. How it feels depends on the product, how much you have and your own tolerance. Dry mouth and dry eyes are the most common complaints, and a few people mention feeling anxious.

How strong is Blackwater?

Blackwater is usually a high-THC strain. Listings put flower anywhere from about 18% to 25% THC, with very little CBD. Concentrates made from it, like vape cartridges, test far higher, so don't compare those numbers to flower.

If you're new to it, start with a small amount and wait before having more. The THC and CBD for your batch are on the label, and our guide to reading cannabis labels explains what they mean.

Buying Blackwater in Canada

Different producers grow different cuts under this name, and at least one listing gives a slightly different parent, so check the label for the strain details and the batch numbers.

You might find it as dried flower, pre-rolls or vape cartridges. Look at the THC and CBD numbers and the packaging date, since fresher flower keeps more of its grape smell.

Blackwater vs Mendocino Purps

Mendocino Purps is one of Blackwater's parents, and you can smell it in the grape and berry notes they share. The difference is the OG side: Blackwater adds pine, lemon and a bit of gas, and it's usually listed with more THC. Both are described as relaxing, but Blackwater has the heavier, sleepier reputation. If you want a softer, fruitier purple strain, try Mendocino Purps. If you want more weight and a fuel edge, Blackwater is the pick.
