R4 is a hard-to-pin-down CBD-forward hybrid whose lineage runs through Wu #1—a cross of Reclining Buddha and Heartland Cream—plus Blueberry Haze. In its flower, the CBD profile is prominent while THC stays minimal, but the most striking numbers appear in concentrates, where CBD has been measured as high as seventy-nine percent. Taken together, the blend hints at a gentle, medicinally focused experience that remains accessible to new users.
Visually, R4 catches the eye with leafy, rounded spade-shaped nugs that blaze a bright neon green, patched with lighter minty tones and threaded with numerous thin orange pistils. The surface wears sparse, clear crystal trichomes and droplets of sweet, sticky resin that cling to every leaf, signaling its resinous character.
Flavor and aroma unfold as a delicate, fruit-forward profile with hints of blueberry and hazy, layered with an earthy pine undertone, while the aroma settles into mild, sweet berry notes. The high is notably mild, driven by CBD, leaving the user uplifted, pain free, and focused rather than couch-locked. With an even 50/50 balance of indica and sativa effects, R4 is often chosen for relief from chronic pain, epilepsy (including childhood), seizures, tremors, muscle spasms, spasticity, and inflammation.
