Marijuana Strain Descriptions
OG #18 (Private Reserve)
Cannabis Strain Summary
Terpene Profile- Primary
Myrcene (musky, earthy, skunk base - contributes to sedative qualities); Limonene (bright citrus, lemon zest sharpness - mood elevation); Caryophyllene (spicy, peppery complexity with clove and wood notes - CB2 receptor interaction)
Terpene Profile- Secondary
Linalool (subtle floral sweetness, lavender notes - smooths diesel harshness); Pinene (fresh pine undertones - adds clarity to aromatic experience)
The Experience- Common Effects
Mental: elevated mood and contentment; mental relaxation without complete sedation initially; increased sensory appreciation (music, food); introspection or sociability depending on setting; mild spaciness or difficulty with complex thought chains; Physical: deep muscle relaxation and tension release; weighted body sensation particularly in limbs; potential couch-lock during peak (especially higher doses); pain relief and physical comfort; pronounced appetite increase; eventual drowsiness making it evening-suitable
The Experience- Duration
Peak effects: 2-3 hours with notable presence; substantial 'legs' - residual effects 4+ hours reported, especially with larger doses or concentrates; comedown: increased appetite common, gentle drowsiness, smooth transition without crash or irritability
The Experience- Onset
Fast-acting: 5-10 minutes onset when smoked/vaporized; initial phase (0-15 minutes): warming sensation behind eyes and temples; early phase (15-30 minutes): mental effects prominent - fluid thoughts, mood elevation, mental engagement from 30% sativa influence; mid phase (30-60 minutes): body high becomes dominant - physical relaxation spreads downward, muscle tension releases, weighted sensation, indica heritage apparent
The Experience- Potential Side Effects
Dry mouth (common, manageable with hydration); dry eyes (common, eye drops helpful); mild dizziness in newer consumers; headache if overconsumed; occasional anxiety or paranoia in THC-sensitive individuals or when exceeding tolerance; significant coughing when smoking due to resin density
Strain Type
Indica-Dominant Hybrid
Not Recommended For
Morning or early-day use requiring alertness and productivity; high-energy social events or parties; situations demanding sharp mental focus or complex problem-solving; new cannabis consumers or those with low THC tolerance; individuals sensitive to anxiety from high-THC strains
Lineage and Origins
Selected phenotype from OG Kush S1 seeds by DNA Genetics' Reserva Privada (mid-2000s); OG Kush parentage traces to Florida-bred cultivar refined in Southern California (early 1990s); commonly cited genetics include Chemdawg crossed with Lemon Thai and Pakistani Kush; developed in Amsterdam but carries California Kush genetic fingerprint; award-winning: 3rd place Indica 2007 High Times Cannabis Cup; 2nd place Indica 2009 High Times Cannabis Cup; 1st place Indoor Hydro 2011 Spannabis Cup
Cannabanoid Profile
THC: 16-23% typical range (18-21% most common); select phenotypes and concentrates may reach 28%+; CBD: <1% (usually 0.5%); CBG: trace amounts around 1%; THC-dominant profile with negligible CBD creates intense psychoactive experience; best suited for experienced consumers with established tolerance; potency varies by batch, cultivator, growing conditions, and harvest timing
Comparable Strains
Tahoe OG (OG Kush phenotype, similar diesel-pine-citrus, more balanced effects with stronger lemon); Kosher Kush (DNA Genetics, similar terpene profile, sweeter aroma, heavier body effects); True OG (OG Kush descendant, more Hindu Kush earthiness, less sour diesel); SFV OG (San Fernando Valley phenotype, more sativa-leaning with greater mental stimulation); Kimbo Kush (Blackberry Kush x Starfighter, myrcene-dominant, berry undertones, heavier couch-lock)
Thinking about growing your own cannabis?
Cultivation Resilience
Relatively forgiving for OG genetics; minimal hermaphrodite expression with proper stress management; benefits from environmental consistency; responds well to training techniques; prefers warm Mediterranean-like climate but adaptable to various conditions
Cultivation Flowering Time
8-9 weeks (56-63 days) from 12/12 light cycle indoors; some phenotypes benefit from 65-70 day extension for maximum resin maturity; outdoor harvest: late September to early October
Cultivation Yield
Indoor: 500-600g/m² (17.6-21.2 oz/m²); outdoor: 20+ oz per plant; notably improved yields compared to original OG Kush; dense bud structure maximizes harvest weight relative to plant size
Cultivation Plant Structure
Medium-to-tall plants with 50-100% height gain during first 2-3 weeks of flowering; somewhat open branching benefits from training (topping, SCROG); medium-to-large internodal spacing; robust lateral branching; support recommended during late flowering due to bud weight; broader leaves consistent with indica dominance
Cultivation Quality Indicators
Dense, chunky bud structure with minimal stem; thick uniform trichome coverage visible on sugar leaves; vibrant orange/rust pistils well-distributed; strong pungent aroma (muted or hay-like smell indicates poor curing or age); slight stickiness when broken apart from resin presence; even coloration without brown or yellowed sections; properly cured minimum 14 days (30+ optimal); stored at 58-62% RH for terpene and potency preservation
