Blackwater by Cali Connection
Blackwater is one of those legendary, dark-kush cuts that put The Cali Connection on the map for a lot of growers. They took a proven female of the famous Mendo Purps and dusted her with pollen from an SFV OG Kush F3 male, aiming to blend those deep Northern California purple aesthetics with the aggressive, fuel-soaked bite of the OG line. Swerve and the Cali Connection crew really caught lightning in a bottle here, eventually taking home 3rd place Indica at the 2014 LA Cannabis Cup. Later feminized runs even saw them crossing Mendo Purps with a Tahoe OG S1, but the goal remained exactly the same: create a dark, brooding, knockout indica that looks just as dangerous as it smokes.
Growing Blackwater is generally a straightforward affair, making it a solid choice whether you're just starting out or running a massive warehouse. The plants naturally grow out stocky and bushy, meaning you really need to stay on top of your defoliation and topping to push light down into the lower canopy. If you let it go unchecked, it's just going to shade itself out. Flowering usually wraps up in about eight to nine weeks. As you hit the late stages of bloom, you'll start seeing those moody, deep forest greens completely fade out into vibrant purples, contrasted by bright orange hairs and a thick layer of frost. Just remember to throw up a trellis net, because once those nugs start packing on weight, the branches will definitely need the support.
The terpene profile on this one is incredibly distinct. You get smacked in the face with sweet, fruity grape and berry notes right off the bat, followed up by heavy undertones of lemon, pine, and woody spice from the OG side. It's a heavy hitter when it comes to the effects, delivering that classic indica experience. You'll get a brief euphoric lift before a massive, soothing body high completely takes over. A lot of old-school heads keep a jar of Blackwater around specifically for killing physical pain or just checking out after a stressful week. It's a nightcap strain through and through.

Growing Blackwater: what to expect
As an indica-leaning plant, expect a modest stretch after the flip (roughly 50–100%) and dense bud structure — which makes late-flower humidity discipline the main risk: keep RH in the 40s once buds fatten to stay ahead of mold. Growers familiar with The Purps or SFV OG Kush will recognize much of its behavior. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
