SR-71 PK (SR-71 Purple Kush) Strain Overview

SR-71 PK — also referred to as “SR-71 Purple Kush” — is a rare, 100% pure indica strain born from the legendary SR-71 × Purple Kush lineage. Known for its stunning bag appeal and deeply therapeutic effects, this is a strain tailor-made for indica lovers who want pure physical relief with zero mental chaos.
Visually, SR-71 PK stands out. Its buds are dense, chunky, and grape-shaped, dressed in olive green with rich purple hues, dark amber pistils, and a thick, frosted layer of purple-tinted trichomes. Crack a nug open and you’ll get a burst of sweet grape candy mixed with spicy herbal notes and a touch of earthy depth.

The flavor mirrors the aroma — sweet, fruity, and heavily grape-forward, with a warm, spicy finish that’s reminiscent of mulled wine.

The effects are just as memorable. SR-71 PK kicks off with a mellow cerebral lift, calming the mind and smoothing out your mood without making you groggy. Then comes the body high — a heavy, tingling relaxation that settles into every muscle, easing tension and locking you into couch-mode for hours.

With THC usually in the 15–25% range plus 1–3% CBD, this strain is frequently selected for chronic stress, anxiety, mood swings, inflammation, depression, and persistent physical pain.

A gorgeous indica with powerful, long-lasting body relief — SR-71 PK is all about deep comfort.
