Nightmare OG
Nightmare OG
Also known as: Nightmare Fuel
Overview
Nightmare OG is an indica-dominant hybrid (70% indica/30% sativa) cannabis strain developed by Sin City Seeds through a cross of OG#18 and White Nightmare. This powerhouse cultivar emerged in the early-to-mid 2010s as OG genetics gained prominence in legal cannabis markets. Despite its ominous name, community lore suggests it references the strain's ability to end nightmares of insomnia and stress rather than creating unpleasant effects. The strain was bred to celebrate OG18, one of Sin City Seeds' favorite genetics from DNA Genetics, while incorporating the enhanced yield and structure from the White Nightmare lineage.
Nightmare OG produces dense, frosty minty green buds adorned with fat orange hairs and a heavy coating of white crystal trichomes. The strain delivers an intense 28-30% THC content, making it significantly more potent than average cannabis varieties. Its terpene profile is dominated by myrcene (0.6-1.2%), limonene (0.3-0.8%), and beta-caryophyllene (0.2-0.6%), creating the characteristic lemony pine flavor with hints of fresh spicy berries and a woody citrus aroma. The high typically creeps up gradually before launching users into a lifted cerebral state followed by a deeply relaxing, couch-locking body high that can persist for 2-4 hours.

Growing Information
Nightmare OG is considered moderately challenging to cultivate but highly rewarding for experienced growers. Indoor cultivation requires controlled environments with temperatures between 68-78°F and humidity levels around 50-60% during flowering. The strain responds well to training techniques like topping and low-stress training (LST), which can increase yields by 15-20%. Flowering time ranges from 63-70 days (9-10 weeks), with harvest typically occurring 65-80 days after flowering onset. Indoor yields average 350-600 grams per square meter under optimal conditions, while outdoor cultivation can produce 500-800 grams per plant in sunny conditions. The strain thrives in both soil and hydroponic setups, though organic soil medium is recommended for optimal terpene expression. Proper curing for 2-4 weeks in controlled low-humidity conditions is essential for maximizing flavor and potency.
