What is GMO Cookies?
GMO Cookies (also known as "Garlic Cookies" or simply "GMO") is an Indica-dominant powerhouse cut from a cross between Chemdawg and Girl Scout Cookies. THC routinely tests at 24-30% — making GMO one of the most consistently high-potency strains in the modern market. Its aroma is unmistakable: pungent garlic, savory funk, hot diesel, and roasted coffee notes that have made it a connoisseur favorite. Royal King Seeds carries stabilized feminized GMO Cookies across our regional shops, with germination-guaranteed seeds and discreet international shipping.
Reported effects
GMO Cookies delivers a heavy, full-body relaxation that begins in the head as a euphoric, almost gravitational sedation and settles into deep limb-heavy stoning. This is a strain best reserved for evening or "couch-locked" consumption — first-time users at typical 26%+ THC will likely experience strong appetite stimulation, drowsiness, and reduced motor function.
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.
Growing GMO Cookies
GMO Cookies is moderately demanding — vigorous, with high nutrient appetite (EC 1.8-2.2 in mid-flower) and sensitive to high humidity in late flower. The plants stretch 1.5-2x in early flower and benefit from topping, mainlining, or aggressive LST. Indoor SCROG yields 500-600 g/m² over 9-10 weeks. Outdoors, plant in May (northern hemisphere) and harvest by early-to-mid October before fall rains; the dense buds are mold-prone if RH exceeds 55%. Defoliate at day 21 and day 42 for better light penetration. Trichome production is heavy — frosty buds with high bag appeal.
