Heavy OG Strain Profile
Classic OG genetics with a heavy hand: compact, frost-covered buds and a nose that opens on dark roasted coffee and pitchy, tar-like fuel before settling into something floral and faintly sweet. Grinds sticky, burns slow. This is the smalls grade, meaning the smaller buds off the same lab-tested harvest — identical genetics, identical numbers, just less bag appeal and a friendlier price. At a full ounce it’s the best per-gram value we carry on this strain.

• Lowest cost per gram on Heavy OG at our shop
• One batch, one COA — consistent from first gram to last
