What is Fire OG?
Fire OG is one of the strongest OG Kush phenotypes — a cross of OG Kush with San Fernando Valley OG, testing at 20-24% THC. The fiery red-pistil flowers and intensely peppery-lemon-pine aroma make it visually and aromatically distinct from other OG cuts. Royal King Seeds offers feminized Fire OG with stable expression.
Reported effects
Fire OG delivers a heavy, full-body relaxation after an initial euphoric rush — best for evening or pre-bed use. Higher doses are sleep-aiding. Caryophyllene + myrcene drive the peppery-gas character.
These are consumption effects reported by growers and consumers for this cultivar. Nothing here is medical advice or a claim that this plant treats, prevents or relieves any condition.
